The occasion of this research paper is the master thesis of the study Management of Technology on the Delft University of Technology.
The research topic is part of the research program of the department Economics of Innovation from the Faculty Technology, Policy and Management.
This master thesis is good for 30 ECTS which means that the duration of the project is approximately six months.
The project itself was performed during an internship at a Fast Moving Consumer Good
(FMCG) company where the assignment was placed at a Laundry Product Research Department.
Therefore, this research has a more business related topic which can be used by the FMCG company to improve their businesses in this area.
During this project, several disciplines were covered which are taught during the MOT program.
Examples of these disciplines are quantitative research methods and innovation management.
I would like to thank my daily supervisor from the company, Paul Stevens, and my section head,
Emmanuel Narinx, for their help and support during this project and providing me with the freedom to complete this project during the past six months.
I had a great time at the department where I had the chance to meet many wonderful people.
This work could not have been occurred without the help of many people such as Angela Phillips, Nancy Vandamme, Marianne Bouvette and many more.
The time, effort and energy that all these people put into this internship was amazing and helped me to make my time in the company a great learning experience.
Besides my colleagues, I would to special thanks to the other (summer) interns for their help, support and company during the time we spend together.
They made my time during the internship truly wonderful and they made sure I had a good time during and after work.
Living together in an unknown city was a fun experience and I am sure I will see many of them soon again.
Lastly, I would like to acknowledge my supervisors from the TU Delft.
I would like to thank dr.
Zenlin
Kwee from the TU Delft who supported me from a distance.
It is not easy to help a student who is not nearby and therefore I would like to thank her for her support and faith in the project.
Finally, I would like to thank prof.dr.
Kleinknecht and dr.
Martin de Jong for participating in my master thesis panel, for their guidance during this project and their valuable feedback on the results and the report.

Due to the opening of Central and Eastern European borders, many multinational companies see opportunities for their products in these regions.
However, these markets are not similar to the markets they usually operate in.
Local customization strategies are required in order to expand their market share not only for cultural bounded products but also for non ‐ cultural bounded products such as laundry detergents.
Companies producing laundry detergents used to have holistic strategies for their products but now recognize that local customization strategies of marketing are needed and a better understanding of specific consumer needs is required.
The aim of this research is to find out how Fast Moving Consumer Goods companies can perform an effective and fast market research to investigate what excites consumers most in a laundry detergent product and what trade ‐ offs are made between price and product attributes.
A quantitative research method is developed for the laundry detergent market in which a conjoint and
Maxdiff test are combined in a so ‐ called virtual prototyping test.
The usefulness of this virtual prototyping test is illustrated in a case study for a FMCG company.
Together with consumers, an attribute ‐ based conjoint test interface is developed which can provide valuable information on which product attribute is most important at which price level.
It will give insights on trade ‐ off behaviour of consumers and its influence on the Overall Rating of the product.
The same consumers help to design a maximum difference scaling test in which consumers have to select their most and least preferred statement out of a set of benefit statements.
This provides a rank ‐ order of benefit statements and benefit vectors.
Together, these two tests provide a holistic understanding of the consumer.
It helps companies to gain fast and accurate knowledge on their key consumers and to apply this knowledge in a local customized product strategy.
The virtual prototyping test was performed in a central location among consumers.
To the knowledge of the author, this research shows the first combination of a conjoint and Maxdiff test.
Consumers are able to answer the questionnaires without further help and the results show a clear distinction in data between different consumer groups and segments.
This indicates that all product attributes and price are considered by consumers in the test interface.
These conjoint models reveal there is a non ‐ linear and asymmetric relationship between product attribute and consumer acceptance which makes the Kano model a useful tool to analyse the conjoint data curves.
This research shows that a combination of a conjoint and a Maxdiff test can reveal important information on key consumer groups.
A clear interface is developed which can be used on internet panels in the future for rapid prototyping.
The case study demonstrates that the virtual prototyping test helps to sharpen the localized strategy and to steer product modifications and formulations to gain a better market position.

Introduction
Due to the opening of Central and Eastern European borders, many multinational companies see opportunities for their products in these regions.
Since the 1990s, Fast Moving Consumer Goods
(FMCG) companies have tried to penetrate the Eastern European markets with their products.
However, these markets are not similar to the markets they usually operate in.
Therefore, local customization strategies are required in order to expand their market share in these regions.
Not only cultural bounded products but also non ‐ cultural bounded products such as laundry detergents suffer from this principle.
Companies producing laundry detergents used to develop holistic strategies for the whole Eastern European area.
Now, they recognize that local customization strategies of marketing are needed.
This thesis report will therefore focus on how these FMCG companies can perform an efficient market research to develop the ideal strategy for their laundry detergent in the specified area of interest.
The main question to be answered in this report is defined as:
How can FMCG companies perform an effective market research in Russia to
2.
investigate what excites consumers most in laundry detergent products and what trade ‐ offs are made by consumers?
A quantitative research method is developed for the specified laundry detergent market.
This method is based on two concepts often used in market research; the first method is a conjoint test and the second method is a maximum difference scaling test.
These two methodologies will be combined in a virtual product prototyping test in which consumers are exposed to a virtual product experience.
This virtual product experience shows the performance of non ‐ existing products on a computer screen and forces consumers to make trade ‐ offs between different concept products.
These consumers have to choose the product they are willing to buy based on product performance and product benefit.
The results of this virtual product prototyping test can be used to model relative impact of claimed product benefits on overall consumer acceptance of the product.
1.1
Research Questions
To perform this research in an orderly and efficient manner and to delineate the research, some research questions have been developed based on the main question stated in the introduction.
The first two sub ‐ questions regard the development of an interface which can be used by companies to leverage the knowledge on consumers and their product preferences.
One of the main targets in this research will be to find a test interface which highlights the different trade ‐ offs made by consumers.
Furthermore, the test data has to be analysed in an efficient way to ensure a high speed ‐ to ‐ market capability of new and/or improved products.
Therefore, the first two sub ‐ questions are formulated as:
‐ 11 ‐
1.
Introduction
1.
What is the ideal test interface for the virtual product prototyping test to leverage the knowledge on consumer preference and product trade ‐ offs?
2.
How can the results of the conjoint and maximum difference scaling test be used to get a better understanding of consumer wishes?
To illustrate the effectiveness of the test interfaces and to check if the analysis methodology is sufficient to gather fast and accurate recommendations from the data, the test will be placed in the context of a market research for an FMCG company This case study should find out if the test interface can reveal the best product strategy for the brand.
Hence, the third and fourth sub ‐ questions are defined as:
3.
Which product benefits of the brane can best excite’s strategic target in Russia with special
emphasis on current Tier 3 users within’s strategic target?
4.
Which local customization strategy should be applied by P to excite Russian consumers with the laundry detergent brand ?
The four sub ‐ questions can be divided into two groups: one group is more scientific orientated while the other group is more focused on the brand of the FMCG company.
However, all four sub ‐ questions will help to answer the main question which is to develop a new methodology to gain fast and accurate knowledge on consumer needs in the laundry detergent market.
The literature discussion in the next chapter will reveal two useful methodologies which are helpful in answering the main question.
These two methodologies are the conjoint and Maxdiff tests which will be combined in a virtual prototyping setting.
However, both tests have not yet been implemented in the field of laundry detergents.
The two methodologies are very suitable for combining with an on ‐ line panel to increase the speed ‐ to ‐ market of new products.
This requires that the interface must be digital and in such a way that consumers can use the interface independently without help of a third person.
After the two test interfaces are designed, the tests will be placed in
Russia.
When the data comes back, a fast and efficient way of analysing the results must be developed.
Especially for the Maxdiff test, there is little known on how to interpret the data in a meaningful and consistent way.
With new software on the market such as Sawtooth Statistics and
JMP Software, it becomes easier to analyse the data.
Next, an overview of the used literature (chapter 2) will be provided including information on the chemical properties of laundry detergents, the market and information on the brand.
Furthermore, it will give more information on the two methodologies which are used as the backbone for the virtual product prototyping test.
Then, the third chapter will propose a theoretical framework.
This is followed by the research methods used in this research and the operationalization of the variables from the theoretical framework (chapter 4).
Next, an overview of the test data (chapter 5) and a discussion on these data (chapter 6) will be presented.
This thesis report will finish with a conclusion in chapter seven and recommendations for further research and recommendations (chapter 8).

Literature Review
This chapter contains an overview of the literature used during this research.
The four P’s of the marketing mix (i.e.
price, place, product and promotion), will be used as a guideline to receive a description of the laundry detergent market of interest.
This is followed by a discussion on consumer involvement in the development of a local customized product strategy.
The chapter ends with a literature overview on the different methodologies which will be used during this research such as virtual prototyping, conjoint analysis and maximum difference scaling tests.
2.1
Laundry Detergent products
A laundry detergent is a common product which is used on a daily basis by millions of people worldwide.
However, not many people recognize that the science and chemistry behind an ordinary laundry detergent is actually very complex.
It contains over 50 different types of ingredients and over 200 actual ingredients (P&G 2007).
Each of these has its own function to make your clothes clean and fresh.
Designing a laundry detergent which completely fulfils the needs of a consumer segment can thus be a challenging activity.
Only 25% of the dirt on clothes can be seen by the consumer where the other 75% of the dirt is hidden on or inside the laundry.
A typical wash load of approximately 3 kg contains around 40g of soil which can be classified in different groups.
Table 1 shows an overview of these different groups and its relative presence in a typical wash load (P&G 2007).
It becomes clear that a laundry detergent is able to focus on different types of dirt and stains.
Depending on the preferences of the consumer, the laundry detergent has to be adjusted to perform best in that specific area.
In order to remove all these different types of soil, a laundry detergent has several functions to fulfil.
These functions are divided in six steps which are summarized in Figure 1.
First, the detergent will hydrate the soil followed by the removal of the soil by using both chemicals and attrition.
When the soil comes loose from the fabric it has to be fragmented in order to dissolve in the liquid.
After the soil has been broken down into smaller pieces, anti ‐ re ‐ deposition chemicals make sure the soil cannot reattach to the fabric while the bleaching chemicals in the detergent make sure that the residual soil will be bleached.
The last step of the detergent mechanism is the fibre modification which makes sure that the clothes feel soft and the colour of the clothes will not fade.

Literature Review
Figure 1: Soil removal mechanism of a laundry detergent (Bodet and Gualco 2011).
Each of these functions is performed by a formulation block of chemicals or a combination of these blocks.
In order to understand how to improve a laundry detergent, it is of vital importance to know what parameters can be adjusted and what these parameters do.
Each formulation block can have a significant effect on how consumers experience the detergent and the process of doing laundry.
During this research, only four formulation blocks will be distinguished and considered to be adjustable.
These four formulation blocks are based on the chemicals of a detergent.
Furthermore, the performance of a laundry detergent is often described in terms of stain/soil removal, whiteness/brightness, perfume and care attributes such as softness, fabric care and colour protection (López ‐ Mahía, Muniategui et al.
2005; Yangxin, Zhao et al.
2008).
The four formulation blocks are defined as:
1) Cleaning: cleaning is the overall removal of (accidental) stains and soil.
It refers to the removal of concentrated soil on clothes and the overall cleaning of the item.
2) Whiteness: this refers to the overall brightness of your white clothes.
Detergents can make your clothes shining white and/or renew whites back to new after they became dull and dingy.
3) Care: this is a broad formulation block which refers to the maintenance of the fabric texture, preventing colour fading and providing softness and a nice fabric feel after washing.
4) Freshness: freshness refers to the scent of the detergent.
It can relate back to wet laundry clothes after wash or dried clothes when using/wearing them.
2.2
Laundry Detergent Market
Laundry detergents are part of the FMCG market and are used all over the world.
It is considered to be a slow ‐ growth market with fierce competition between three main players: Procter & Gamble,
Unilever and Henkel (Slater and Olson 2002).
This section will describe the market of laundry detergents.

Literature Review
2.2.1
FMCG Market Characteristics
Since the opening of Central and Eastern Europe borders, many Multinational Companies (MNCs) see opportunities for their products in these regions.
These MNCs believe that highly standardized products can be used in these types of markets as they are convinced of the fact that European markets become more and more homogeneous.
However, research has shown that local customization strategies in Central and Eastern Europe often show best results (Schuh 2007).
In order to apply local customization on products, a holistic understanding of the Central and Eastern
European market is needed to identify similarities and differences in the cultural, political and economic environment.
Research has shown that continuous market penetration of Fast Moving
Consumer Goods (FMCG) has occurred since the 1990s (Schuh 2007).
International brands have gained footage on these markets especially in the less cultural bounded products like detergents.
However, local food products still remain more popular compared to international food brands and there is still a lot to win for MNCs in these FMCG markets (Schuh 2007).
This indicates that local customization strategies of marketing and a better understanding of cultural diversity is needed for firms in order to succeed in Central and Eastern Europe (Mooij 2009).
There are two methods suggested in literature on how companies can gain a better understanding of their consumers (Kim and Atuahene ‐ Gima 2010).
The first method suggested is exploratory organizational learning.
Exploratory market learning is used to gain knowledge from outside the organizations’ current boundaries and provides information about consumers and competitors.
The second method suggested in literature is the exploitative organizational learning which uses consumer and competitor information within the neighbourhood of the firm’s current expertise in order to provide a deeper understanding of the consumers’ actions and needs.
Especially exploitative market learning can help companies to gain more knowledge on consumer needs and reasons why people reject new technologies.
As individuals reject new technologies for different reasons, it is important to know the needs of the consumers when considering to innovate new or existing products
(Onwezen 2011).
Examples of such reasons for rejection are lack of trustworthiness, lack of knowledge about possible health effects and unwillingness to pay high prices for new product innovations.
Still many companies suffer from an incomplete understanding of their consumers despite their information gathering through market research.
This incomplete picture prevents managers within companies to take appropriate decisions concerning product innovation (Parry and Song 2010).
One way to solve this incomplete picture is to engage consumers in the innovation process of existing and new products; the so ‐ called customer empowerment (Fuchs and Schreier 2011).
Companies have to transform from a company ‐ centric market strategy towards a consumer ‐ centric market strategy in which consumers are seen as a source of value creation (Prahalad 2004).
Through personalized interactions with consumers, a dialogue is formed which leads to more transparency and a better understanding of consumer needs.
In order to achieve such a dialogue between the company and the consumers, the managers of the company have to invest in new technologies enabling more interaction (Prahalad 2004).

Literature Review
2.2.2
Competitors on the Market
Several competitors can be distinguished on the Eastern Europe laundry market.
The number of competitors observed in the market determine the “threat of substitute products” and the “threat of new entry” according to Porter’s five forces model (Slater and Olson 2002).
These two threats affect the competitive rivalry within the industry which has a big impact on the Return on Investment of the company.
The main producers of laundry detergents and their brands are listed in Table 2.
Each of these producers provides laundry detergents on three price levels: Tier 1, Tier 2 and Tier 3.
The higher the Tier level (i.e.
Tier 1), the higher the price and the more benefits are included in the detergent which results in a better quality of the product.
The global laundry care market consisted of $52 billion dollar in 2009 where a share of 34% for P&G,
18% for Unilever and 11% share for Henkel (HAPPI 2011).
Reckitt ‐ Benckiser and Colgate ‐ Palmolive both held 5% of the market in 2009.
Focusing on the laundry care market of interest, the largest producers of laundry products are P&G with a market share of 47.2% and Henkel with a market share of 29.4% (CEEMEA 2009).
The remaining market share is distributed amongst Unilever (10%),
Reckitt Benckiser and small local producers.
Although both P&G and Henkel are non ‐ native companies, they have gained a big footage on the market which may be due to the non ‐ cultural bounded character of a laundry detergent.
The high market shares of P&G and Henkel make it difficult for new companies to enter the market which reduces the “threat of new entries” .
The Herfindahl ‐ Hirschman index for the laundry detergent market is 0.32
(3,200) indicating a high concentration and thus an oligopolistic market.
The oligopolistic market characteristic together with the strong brand equities of the main laundry detergent producers, make the “threat of new entries” low.
The “threat of substitute products” is low as there are not many different laundry products on the market.
However, this does not necessarily mean that the “ bargaining power of customers” is limited.
The switching costs for consumers are low which means that the companies have to keep the customers satisfied and need to listen to their wishes very carefully.
Customers can easily switch products if they are not satisfied.
The “ bargaining power of the suppliers” is relatively big as modern trade is only 45% of the market while open markets represent a large part of the trade (CEEMEA 2009).
P&G has with 8,576 million euro (P&G 2010) the highest investments in marketing compared to 4,257 million euro for Henkel
(Henkel 2010) and 1445 million euro for Unilever (Unilever 2010).
Based on these numbers, it can be concluded that the “intensity of competitive rivalry” is limited for P&G but is high for Henkel and
Unilever.

Literature Review
With four well ‐ known brands on the Russian market (i.e.
Ariel, Persil, Losk, Tide), the threat of substitute products is relatively high.
Therefore, both P&G and Henkel constantly need to improve their products to keep consumers satisfied and to maintain their market share.
A more detailed description of the brand is given in section 2.3.
2.2.3
The Laundry Market
The specified detergent market is one of the most important markets in Central and Eastern Europe
(Figure 2).
With approximately 140.04
million inhabitants and 17 million square kilometres, Russia is the largest country in the world by land area.
The country has the world’s 11 th
largest economy in the world by nominal GDP where the average income of an inhabitant is approximately 16,100
US$/year per capita (based on GDP).
With an average family size of 2 to 4 people the consumer belongs to the 6 th
largest by purchasing power parity and belongs to the top 5 of most important markets for the laundry market.
Because of these reasons, this country is an interesting area for
FMCG companies to market their products.
(CEEMEA 2009)
Despite the fact that the economy develops relatively fast, the modern trade only represents 45% of the total laundry volume (supermarkets and minimarkets) (Sipos 2008).
High frequency stores and open markets are still an important channel to trade products.
However, the consumers can be very sceptical when it comes down to product claims.
The average consumer demands more scientific explanation of how the product works compared to other consumers in Central and Eastern Europe
(CEEMEA 2009).
This can partly be explained by a high percentage of people with a higher education and partly by habit of distrust to promises made by the “officials”.
Additionally, dressing good and fashionable is a common practice (CEEMEA 2009).
It is part of their daily standard and a way to maintain social status.

The total laundry market in Central and Eastern Europe (CEE) and its split by country is shown in
Table 3.
This table illustrates that the total laundry market can be divided in a Low Suds (LS) and
High Suds (HS) market.
The LS detergents produce fewer suds and are mostly used in Front Loading
Washing Machines whereas the HS detergents are mainly used for hand washing.
This research will only focus on LS detergents as more and more people switch from hand washing to front loading washing machines.
As can be seen from Table 3, Ru ssia is the biggest market in Central and Eastern
Europe with the largest growth potential in LS as the group of HS consumers is still relatively big.
The total low suds market in ussia is 38,061 MSU for which P has a market share of 47.2% (17,964
MSU).
Market shares are depicted in MSU which represents one thousand statistical units with one statistical unit representing 8 kg of detergent.
The reason for using MSU as a unit is to compare other products with laundry detergents which is essential for a company producing several types of products.
The total high suds market for Russia is considerably smaller with 15,395 MSU and a
Pshare of 35.7% (5496 MSU).
When focusing on the LS market in Russia, ’s share is 15.4% with a market volume of 5,861 MSU.
All these numbers show that the low suds market has potential to grow by converting high suds users to the low suds detergents.
Also Ti d e has room to grow and become an even bigger brand on the market.
The average number of washes for the Russian consumer is 5.2
to 6.0
loads per two weeks.
The most popular package size for the Russian consumer is 400 grams which they buy on average 10 times a year (Sipos 2008).
2.3
Pricing in the Detergent Market
There are only a few key competitors active on the Russian laundry care market as was seen in Table
2 of section 2.2.1.
Each of these large laundry care firms has a relatively large market share, i.e.
small companies represent less than 10% of the market, and the companies are relatively independent with a Herfindahl ‐ Hirschman index of 0.32
(or 3,200).
H
N
i
1 s i
2 (1.1)
Here H is the index number, s is the market share of company i in percentage and N is the total amount of companies on the market.
The higher the Herfindahl ‐ Hirschman index, the larger the independence of the different companies is.
Independence means in this case that the profit earned by each firm is dependent on the firm’s own actions and by the actions of its direct competitors.
Therefore, the laundry detergent market is considered to be an oligopolistic market instead of a perfect competition.
The oligopolistic behaviour directly affects the pricing strategy held by these laundry detergent producers.
The laundry detergent producers have to face a prisoner’s dilemma in
‐ 18 ‐

Literature Review
which they can choose to keep the current price or to decrease the price in order to gain market share.
In most cases, the large laundry detergent producers can be considered to have a pricing leadership.
However, the laundry detergent market is divided into four price categories which reduce the prisoner’s dilemma.
These four price categories are Tier 1 to Tier 4 in which the Tier 1 price category is the highest price category and the Tier 4 is the lowest price category.
The higher Tier price categories represent the top ‐ line products with high performance.
Each pricing category has its own brand to target the consumers within this pricing category.
This reduces in some extend the prisoner’s dilemma as each large detergent producer has a brand in each of the pricing segments and thus target all consumers.
Reducing the price of a Tier 1 brand doesn’t make much sense as then this brand is competing with one of their own Tier 2 brands.
In this research, only the price categories Tier 1 (1.5
kg = €4.20), Tier 2 (1.5
kg = €3.43) and Tier 3 (1.5
kg = €2.48) are considered as these represent the largest part of the laundry market.

Market Segmentation
The laundry market is divided in different segments which are company specific.
Each detergent producer attempts to target one of these segments by adjusting the chemical properties of their brand.
In this case, the segmentation is described and will be used in the remained of the report.
This segmentation is referred to as the new segmentation and will be discussed in detail below.
The segmentations is derived through a process containing 3 stages.
In the first stage a multifunctional alignment is gained to ensure they address the core business issues and that the output is actionable in both upstream and go ‐ to ‐ market stages.
The second stage is the data collection and segmentation definition stage.
Data is collected to leverage existing or new knowledge on hypothesized segmenting and profiling variables.
The consumers are then segmented in an infinite variety of ways.
The challenge in this stage is to identify the few segmenting variables that discriminate consumer behaviour.
The segments must be meaningful from a consumer perspective, attractive from a business standpoint and relevant to the core business to be addressed.
The third stage is about bringing the segment to life using profiling variables to create a robust profile of the segment.

Customer Empowerment in Product Development
One technology to improve the interaction with consumers and thereby the understanding on the up ‐ tiering consumers behaviour is the internet.
The internet can be used as an interactive platform in which online consumer communities are formed (Fuchs and Schreier 2011).
Internet enables firms to engage with consumers in the innovation process.
Research indicates that the internet allows firms to interact with consumers more broadly, more richly and faster.
It creates an on ‐ going
‐ 19 ‐
2.
Literature Review dialogue between the consumers and the firm in which the firm is neither limited by geographical nor market boundaries.
It gives these firms the capacity to tap into the social dimensions of consumer knowledge (Sawhney 2005).
The internet platform can be used in different stages of the product innovation process.
A trade ‐ off must be made by the firm between reach and richness
(Sawhney 2005).
When the company is interested in generating new ideas and insights, richness is chosen while reach enables a firm to validate hypotheses.
Many companies already use internet platforms like advisory panels; an example of such advisory panel is the one from Procter & Gamble (P&G) with their P&G Advisory program (Sawhney 2005).
This online advisory program allows P&G to integrate their consumers’ innovative new product ideas into the development process more actively, more directly and more systematically (Fuchs and
Schreier 2011).
2.7
Virtual Prototyping
Besides improving the interaction with consumers, the internet offers an attractive environment for new product market research; virtual prototyping.
The costs of building and testing virtual prototypes are considerably lower which allows more product concepts to be tested within the same budget.
The access to respondents is efficient and fast feedback can be provided using the internet.
Nevertheless, the internet may result in sample bias from using web ‐ based respondents only (Dahan and Srinivasan 2000).
Virtual prototypes help to gain an accurate assessment of consumer acceptance which will enable better customized products.
Not only price competition but also competition on product variety and speed to market determine the success of a product on the market (Tseng, Jiao et al.
1998).
Consequently, (local) customization of products becomes an important marketing instrument because old products constantly need improvements and new variations on old products need to be introduced.
Short product cycles are crucial for a company’s success.
Virtual prototyping provides a rapid prototyping environment in which concepts can be developed and tested using simulations.
Research has shown that an attractive appearance draws customers to a product and increases customer preferences (Tseng, Jiao et al.
1998).
However, preference of laundry detergents is mostly based on performance rather than appearance.
Identifying the elements that enhances the consumer acceptance of laundry products requires a different approach of virtual prototyping.
A conjoint analysis is a widely used methodology to measure preferences for different products and to build market simulation models to predict market shares.
Unfortunately, these conjoint methods are again focused on aesthetics and looks of the product and not on the performance of the product.
A conjoint interface must be developed and used which tells the user how the prototype will perform and behave in its intended environment.
This approach is called analytical virtual prototyping which normally uses standard computing techniques (Tseng, Jiao et al.
1998).
Testing prototypes is one side, whereas the most challenging decisions faced by a new product development team is concept selection; the narrowing of multiple product concepts to a single, best design (Dahan and Srinivasan 2000).
There are two ways to select the best concept: prototyping and testing.
With many FMCG companies on the market, time to market is critical in the laundry
‐ 20 ‐

Literature Review
detergent market.
The number of tested prototypes increases with the increased importance of time to market (Dahan and Srinivasan 2000).
Therefore, a suitable method must be used to test a large amount of prototypes in a short time as only a small percentage of the total number of prototypes proves to be profitable and a success on the market (Dahan and Srinivasan 2000).
2.7.1
Conjoint methodology
A methodology which can be used in the product innovation process is the quantitative conjoint analysis.
Product innovation is generally conceptualized as a five ‐ stage New Product Development
(NPD) process consisting of ideation, concept development, product design, product testing and product introduction (Sawhney 2005).
By using consumer input through the conjoint technique, companies can create new product faster.
The conjoint analysis test can be used to create, test and refine new product concepts in a fast and efficient manner (Sawhney 2005).
A special form of the conjoint analysis is the attribute ‐ based conjoint analysis which refers to the understanding of customer trade ‐ offs on multiple product attributes and price.
The design team generates multiple product concepts that address customers’ needs for both quantifiable performance attributes and qualitative attributes such as aesthetics and ease ‐ of ‐ use (Dahan and
Srinivasan 2000).
Whereas attribute based conjoint analysis explains a significant portion of the variability in product preferences, it does not explain preferences resulting from design issues such as aesthetics and ease of use (Srinivasan, Lovejoy et al.
1997).
However, for laundry products this is not a big issue as the consumer preference is mostly based on performance and not on aesthetics of the laundry detergent.
During the attribute ‐ based conjoint test, the consumer is asked to answer questions showing virtual concepts.
The concepts are accompanied by different attribute areas and their performance levels by means of a virtual communication interface.
The consumer is then asked to choose the virtual product she is willing to buy for the indicated price.
The consumer is forced to make a trade ‐ off between the different performance levels of attributes and its price.
It will be used to understand how consumers build their preferences for detergents and how they combine the value of a product with the value provided by each attribute.
The attribute ‐ based conjoint test can provide valuable information on which benefit attribute is most important at which price level.
It will give insights on trade ‐ off behaviour of consumers and the influence on the Value and the Overall Rating of the product.
2.7.2
Maximum Difference Scaling methodology
Another method often used in market research is the so ‐ called maximum difference scaling test
(Maxdiff).
A respondent is asked to select both the best and worst option in an available (sub)set of choice alternatives.
The assumption behind this method is that individuals can identify the best and worst items in sets of three or more and that the pair chosen by a person in any particular set is the pair perceived to be the farthest apart on an underlying scale (Louviere and Islam 1998).
Despite the increased use of Maxdiff methodologies, the underlying model has not been revealed entirely,
‐ 21 ‐
2.
Literature Review resulting in unclear guidelines on appropriate experimental designs, data analysis and interpretation of results (Marley and Pihlens 2011).
The Maxdiff methodology is in fact an extension of paired comparisons which is an established methodology in sensory and consumer sciences (Jaeger, Jorgensen et al.
2008).
The methodology adds a further layer of sophistication by identifying not only the best item but also the worst item.
In this way, it provides more information compared to paired comparison method.
Furthermore, the best ‐ worst choice data can be transformed to a probability scale when analysed by a multi ‐ nominal logic (Jaeger, Jorgensen et al.
2008).
This is in contrast to the rating scales in which theoretical scaling properties are unknown.
There is often little differentiation among attribute importance measured on a category rating scales.
The advantage of the rating scale is that it requires little time on each rating and all attributes are rated relatively important.
However, the maximum difference scaling approach has a cognitive psychology basis, which is easy to implement and in which it is easy to make trade ‐ offs between attributes (Louviere and Islam 1998).
Another advantage of the Maxdiff methodology is that an increased discrimination among items is achieved.
To the knowledge of the author of this thesis report, no previous published studies exist that combine both a conjoint and Maxdiff methodology together in a market research to perceive a better understanding on consumer behaviour.

Theoretical Framework
In this chapter a theoretical framework is proposed which will set the foundation of the research.
This theoretical framework will represent the beliefs on how the consumer acceptance of a laundry detergent is influenced by different parameters.
The full theoretical framework is presented in
Figure 3 in paragraph 4.2.
First the different variables will be discussed followed by a thorough discussion of the theoretical framework itself.
3.1
Variables
The variable of interest in this research is the consumer acceptance of the laundry detergent which is represented by a so ‐ called Weighted Purchase Intent (WPI) or willingness to pay.
The WPI is derived from the welfare economics.
It represents the marginal rate of substitution of particular attributes for money.
There are two advantages of using the WPI as a measure for consumer acceptance (Louviere and Islam 1998):
1) The utility for each attribute in a conjoint test is measured on an interval scale which is unique to each attribute and individual.
This makes it impossible to compare estimated attribute utilities.
The measure of WPI for each attribute is stated in common dollars/euros allowing comparison.
2) All discrete choice models blur the magnitudes of estimated attribute parameters with the error variance of individuals such that large error variances lead to small parameter estimates.
The WPI ratios cancel this blurring behaviour between individuals, allowing a clear comparison of the numbers.
A high weighted purchase intent indicates that consumers are sufficiently excited by the product and thus willing to spend money on the product.
Therefore, it is important to discover how the WPI is influenced by different independent, moderating and intervening variables.
A good local customized strategy should eventually lead to a higher WPI and thereby preserve or increase the market share of the brand.
The relationship between the different attribute levels of the product, the overall rating of the product (OAR) and the WPI is of critical importance for managers in a customer ‐ driven organization.
A high overall rating increases loyalty, reduces price elasticity, increases cross ‐ buying and results in a positive word to mouth (Matzler, Bailom et al.
2004).
In other words, high attribute levels result in a high overall rating which eventually leads to a higher WPI.
The relationship between attribute level,
OAR and WPI used to be conceptualized as linear and symmetric.
However, research has shown that negative performance of an attribute has a greater impact on the overall rating and WPI compared to a positive performance on the same attributes (Mittal, Ross Jr.
et al.
1998).
Thus, attribute satisfaction and dissatisfaction have a significant effect on the overall rating of a product where dissatisfaction has a larger weight compared to satisfaction.
It is thought that the attribute performances affect satisfaction and WPI in a different way.
Satisfaction is a judgment with cognitive and affective dimensions, whereas repurchase intension also has a behavioural
‐ 23 ‐
3.
Theoretical Framework component.
Therefore, the overall rating and performance are related nonlinearly to repurchase intentions or loyalty.
(Mittal, Ross Jr.
et al.
1998)
Previous research shows that attribute performance has an indirect impact on repurchase intentions through its effect on the overall rating of the product (Mittal, Ross Jr.
et al.
1998).
Multiple regression models are normally used to identify the key attributes of a product in which managers should invest their (limited) resources.
The assumption underneath these so ‐ called key ‐ driver models is the existence of a symmetric and linear relationship between attribute performance, overall rating and WPI.
Several reasons can be identified for implementing a multiple regression model (Mittal, Ross Jr.
et al.
1998).
First, consumers evaluate the product based on their post purchase expectations of satisfaction at an attribute level rather than at the product level.
Second, an approach based on attributes enables researchers to conceptualize common observed phenomena.
Mixed feelings might exist as consumers may be satisfied with some of the attributes but dissatisfied with the other attributes.
Therefore, studying the overall rating at an attribute level can help extend both the conceptual and the empirical understanding of the phenomena (Mittal,
Ross Jr.
et al.
1998).
The importance ‐ performance analysis (IPA) has long been an important model to investigate the relationship between quality attribute performance and overall rating (Matzler, Bailom et al.
2004).
The assumption behind this model was the linear relationship between these two factors and the symmetric behaviour.
However, research from Mittal et al.
showed that there exist a non ‐ linear and non ‐ symmetric relationship between quality attribute performance and OAR.
Kano’s model of satisfaction also disconfirms the basic assumption of the IPA model (Matzler, Bailom et al.
2004).
Kano states that satisfaction is formed through a cognitive comparison of perceived performance and pre ‐ purchase expectations.
This Kano model of satisfaction will be used in combination with the conjoint test data to develop useful recommendations for the company.
The Kano model will be further explained in the next chapter.
Another methodology often used to identify the relationship between attributes and overall rating is the linear regression method.
Because of the collinearity among the attribute performances when used as predictors of overall performance, this method can lead to poor precision of the regression coefficients (Abalo, Varela et al.
2007).
A second criticism of linear regression method is that the relationship between the overall performance of a product and its performance with respect to its individual attributes may well be nonlinear.
As is discussed earlier, the conjoint analysis may be a better option as this method has the advantage of using an orthogonal design which excludes the possibility of collinearity (Abalo, Varela et al.
2007).
Furthermore, the use of several levels for each attribute reduces the risk of non ‐ linear dependence of the overall rating on attribute performances.
However, the disadvantage of the conjoint analysis is that it requires a large data collection process and becomes unfeasible when involving more than a very few attributes.
(Abalo, Varela et al.
2007)
Thus, the weighted purchase intent is influenced by the overall rating of the product which, on his turn, is influenced by the performance of several product attributes.
The next step is to identify the main product attributes.
When identifying these attributes it should be reminded that the number
‐ 24 ‐
3.
Theoretical Framework
of attributes should be limited.
The reason for limiting the number of attributes is that the data collection process becomes unfeasible when involving more than a few attribute areas.
There are four product attribute areas chosen based on the chemical properties of a laundry detergent.
In chapter 2 a description of the different chemical building blocks was given and four main building blocks were identified.
These four building blocks will be used as the basis for four product attributes which will be used in the theoretical framework.
These four attributes are treated as independent variables as they can be adjusted by the chemical configuration of the laundry detergent.
In this theoretical framework, the four performance vectors are pictured as independent variables but in reality these four vectors influence each other and can cause multi co ‐ linearity issues.
An increase/decrease in one can cause an increase or decrease in one or more of the other vectors.
In order to fully understand the influence of these four performance vectors, these will be discussed separately.
Whiteness: The performance vectors whiteness and cleaning are closely related.
When focusing on the vector whiteness, the actual brightness of the white fabric is meant.
Laundry detergents can give a blue or pink hue to white fabric depending on the preference of the region/country.
Therefore, the perception of whiteness is preference based and can influence the WPI and OAR of the detergent.
Cleaning: As explained earlier, whiteness and cleaning are closely related.
When talking about cleaning, the actual stain removal on fabrics is meant.
Different types of stains are possible and each detergent targets different groups of stains.
The cleaning vector can have a large impact on the WPI and the AOR of a laundry detergent product.
Care: The variable care is harder to explain as each consumer can interpret this vector in a different way.
Care can be subdivided into several categories: care for fabric, colour care, softness and skin care.
Each of these attributes determines the overall rating for care.
However, the weights put on each of these attributes can differ among consumers and among countries.
Freshness: The vector freshness is related to the scent of the detergent.
During the laundry process, there are different moments when consumers experience the scent of the detergent: when opening the package of the laundry product itself, during drying the wet clothes, the scent in the washing room, the dry scent when putting the clothes in the closet, the scent during wearing and the cupboard scent.
Each of these scent experiences can have a large impact on the product experience and thereby on the WPI and OAR of the product.
However, the OAR is not only influenced by these four product attributes.
There are also some moderating variables which have a strong contingent effect on the overall product rating and thereby influencing the WPI.
One of these moderating variables is the brand equity.
The value of a brand lies in what consumers have experienced with the brand in the past.
This past experience constitutes a brand image which has a large effect on the behaviour of the consumer.
Therefore, brand associations are very important building blocks for customer ‐ based brand equity (Torres and
Bijmolt 2009).
The association is from the brand to the product attribute and the other way around.
‐ 25 ‐
3.
Theoretical Framework
Brand equity consists of two components: brand awareness and brand image.
Brand awareness is related to the strength of the brand as reflected by the ability to identify the brand under different conditions while brand image can be defines as the consumers’ perception about a brand as reflected by brand associations held in memory (Torres and Bijmolt 2009).
Especially the brand association held in memories are affected by past experience with the brand and is defined by the different product attributes.
Consumers generally use brand awareness as a decision heuristic in which they link the related brand knowledge to the brand name, which finally constitutes brand equity.
In general, literature indicates a positive relationship between brand awareness and market outcome.
However, other factors such as the shopping environment, product placement, and on ‐ the ‐ spot promotion, are also likely to influence the purchase decision.
(Huang and Sarigöllü 2012) Therefore, it is important to include brand equity in the theoretical framework as a moderating variable.
Each product is accompanied by one or more benefits which are captured in a statement.
The way this statement is set up and communicated towards the consumer can influence the WPI and OAR independent of the product attributes.
This is strongly related to the concept communication as most concepts are covered in a benefit statement.
However, concept communication includes more such as commercials, packaging and images.
3.2
Theoretical Framework
In Figure 3, a schematic representation of the theoretical framework is shown.
As can be seen from this picture, the product attributes have a direct influence on the overall rating.
However, the benefit statements and the Brand Equity have a disturbing effect on this relationship.
In the end, the
OAR determines the weighted purchase intend of the product and thus the product satisfaction.
Figure 3: Theoretical framework as proposed in this research report.
There are four independent variables which affect two intervening variables.
These intervening variables are also affected by one moderating variable.
The dependent variable is the consumer’s affinity to the brand.
Despite this figure implicates the use of a linear regression method, this method will not be used due to some disadvantages as discussed earlier.
Because of the collinearity among the attribute
‐ 26 ‐
3.
Theoretical Framework
performances when used as predictors of overall performance, this method can lead to poor precision of the regression coefficients and the relationship between the overall performance of a product and its performance with respect to its individual attributes may well be nonlinear (Abalo,
Varela et al.
2007).
Therefore, the relationship between the four product attributes and the overall rating of the product will be investigated by means of the Kano model and by means of so ‐ called desirability functions.
This is further explained in the next chapter.
The first challenge is to design a test which provides more insight in the relationship between the four benefit attributes and their effects on the overall rating.
During this test, the effect of the moderating variables on the overall rating is reduced by not including brand names and benefit statements in the conjoint test.
The next challenge is to investigate the effect of the moderating variables on the overall rating.
The effect of the brand equity and the effect of the concept of the product will not be considered in this research.
To investigate the effect of benefit statements on the overall rating, the Maxdiff test will be developed.
More information on the different research methods will be given in the next chapter.

Research Methods
Several data collection methods were proposed in chapter 2 and 4.
This chapter provides an outline of the proposed research methods illustrated with a few examples.
The second part of this chapter will discuss the operationalization of the different variables of the theoretical framework as described in the previous chapter.
4.1
Data Collection Procedures
The different data collection procedures will be discussed in this section.
Both Qualitative and quantitative data collection procedures are used.
Qualitative research will be used to develop a quantitative test which will be placed among consumers.
The results from the quantitative test will be supported and verified by further qualitative data derived from an internet panel.
4.1.1
Qualitative Research
The qualitative part of this research will be performed in two ways: by means of consumer interviews in a so ‐ called consumer lounge and by means of an internet panel.
Both qualitative methods will be based on structured (online) interviews and are discussed below.
Consumer lounge: The consumer lounge is a special facility where consumers can be invited for an in ‐ depth interview.
The facility simulates a living house containing several rooms like a living room, a kitchen, dining room and a bathroom.
Besides the normal housing areas the facility also holds a small supermarket where the shopping behaviour of consumers can be observed.
Each room is provided with cameras and microphones in order to observe consumers during their normal day activity.
The aim of the exploratory interviews in the consumer lounge is to test early interfaces for an online quantitative test to be placed.
The interview consists of three parts which in total takes 1.5
hour.
In the first part the consumer will see different illustrations related to the four benefit areas of laundry detergents: cleaning, whiteness, care and freshness.
These illustrations will be used for communicating the different benefit levels for the conjoint test.
The second part of the interview will be focused on different scales to communicate the level of each benefit area.
Different scales are shown and the respondent is asked to give her opinion on the type of communication.
The last part of the interview will focus on benefit statements in combination with illustrations.
Again, the consumer is asked to give feedback on the combination of the benefit statement and the illustration.
During the interview consumers are constantly stimulated by illustrations in order to visualize their thoughts.
The consumer is talking and the interviewer will interrupt as little as possible.
The interviews took place in the consumer lounge where the respondent was interviewed directly by the interviewer.
The downside of the consumer lounge is that this facility is located in Brussels and not in the target country.
Therefore, the consumers coming to this facility are mainly expats who used to live in their country of origin but have moved to Belgium.
It is therefore important to select the respondents for the consumer lounge based on the time they have spent in their country
‐ 29 ‐
4.
Research Methods of origin and the time they have spent in Belgi um.
The respondents have to be representative for their home country and therefore a limit of 3 years in Be gium is often taken.
Based on these selection criteria, 6 Eastern European female interviewees were selected who are strongly involved in the purchase decision of the laundry products and the laundry process itself.
Internet panel: As explained in the literature research, consumer engagement becomes more and more important in the FMCG market.
Especially involving and engaging consumers in the innovation process of existing and new products become the new challenge as speed ‐ to ‐ market is crucial.
In order to anticipate on this new development, the company decided to launch an internet panel where researchers can post questionnaires, add quick polls, can introduce topics on a forum and can chat with consumers.
By means of this online panel, the company will be able to quickly receive results from an online community.
The internet panel will be used to gather further information on data derived from the quantitative test.
The internet panel will probe on observations from the quantitative test and gather qualitative rather than quantitative data to support hypothesis and observations.
It will help to investigate the influence of brand equity and product concepts on the value of the product and its effect on the overall rating of the product.
The online community consists of consumers divided over different market segments.
For each research, a specific target group can be selected in order to get the right information.
The language used on the internet panel is native which means that each questionnaire will be thoroughly translated and checked before posting.
There are many possibilities with the internet panel, opening a variety of opportunities.
Using these possibilities, a real two ‐ way conversation can be established with the consumer involving them in the innovation process of a product.
It is important to give the consumer the feeling they are taking part in a community and that they can have an influence in the whole innovation process.
Therefore, it is essential to keep the internet panel alive and attractive by posting approximately two questionnaires a week, one quick poll a week and keeping involved on the forum.
4.1.2
Quantitative Research
Quantitative data will be a large part of this research.
In order to perform the quantitative research in an efficient way, the Design of Experiment (DOX) approach will be used.
DOX is a designed experiment containing a test or a series of tests in which purposeful changes are made to the input variables of a process or a system in order to observe and identify reasons for the change in the output of the system (Myers 2007).
The advantage of using the DOX approach is that experiments can be designed in such a way that a minimum of test samples is needed in order to predict the outcomes of a whole group/segment in a statistical and significant manner.
One of these DOX approaches is called the factorial design.
This approach will model all the possible factor combinations and include them in the DOX design.
When each factor has only 2 measurement levels, the total number of test samples is calculated by 2 k
(Myers 2007).
Another DOX approach is the computer generated (custom) design in which the researcher can select the total number of
‐ 30 ‐
4.
Research Methods
samples (Myers 2007).
The program will then select the best combination of samples in order to make statistical representative model.
This approach is very helpful when there is limited time or funding to perform the complete set of test samples.
In this research, the computer generated
(custom) design is used to select the sample base for the conjoint and Maxdiff test.
A Quantitative test will be placed to broaden the consumer knowledge on the laundry market of interest.
This test is based on exploitative organizational learning which uses consumer and competitor information within the neighbourhood of the firm’s current expertise in order to provide a deeper understanding of the consumers’ actions and needs.
It can help companies to gain more knowledge on consumer needs and the reasons why people reject new technologies.
(Onwezen
2011)
Virtual Product Prototyping test: The so ‐ called virtual product prototyping test refers to a conjoint and maximum difference scaling (Maxdiff) test.
The two test methodologies will be combined in a virtual product experience where consumers are confronted with different virtual (non ‐ existing) products.
The Maxdiff methodology will show statements to consumers from which the respondent has to choose the best and worst statement.
More details on the Maxdiff test design will be given in the next chapter.
The conjoint will force respondents to make trade ‐ offs between different product attributes and price which will be further discussed below.
A total base size of 3 45 consumers is recruited with the focus on the strategic target: Organizers,
Protectors and Enjoyers.
An over quota is introduced to make sure the minimum base size for a breakout analysis on the conjoint is established.
Based on the market penetration data this means that there will not be enough Protectors recruited to do a conjoint analysis on this segment.
Reason for not having an over quota for Protectors is budget restrictions.
Another over quota is established regarding the P3M MO Tier 3 consumers.
Recruiting was done using a questionnaire developed by the marketing department.
In total 100 Organizers, 196 Enjoyers and 49 Protectors were recruited.
From this consumer base, 114 Tier 1, 106 Tier 2 and 125 Tier 3 users were recruited which enables a breakout on these user groups.
The analysis of the conjoint data is done in the software JMP.
This statistical software is able to build a model based on different product attributes; in this case the attributes discussed in chapter 4.
The model consist of a so ‐ called prediction profiler based on a desirability function (Ramsey, Stephens et al.
2005).
The desirability is based on values assigned to each consumer response that reflects its desirability.
The JMP software defines the desirability function based on control parameters set by the researcher.
One of these parameters is an importance factor for each attribute which can be included when one attribute weights more to the consumer acceptance compared to another attribute.
Each attribute will be represented by three levels to indicate the performance of the attribute (i.e.
low, medium and high).
The output of this software is given in five graphs in which the performance levels of each attribute can be adjusted independently.
This model takes two ‐ way interactions into consideration which means that sliding one of the sliders on the x ‐ axis affects the steepness/shape of the other four remaining curves.
Only two ‐ way interactions are taken into account as the three ‐ way interactions are too complicated to analyse and interpret.
An example of
‐ 31 ‐
4.
Research Methods one of the conjoint models is shown in Figure 4.
The y ‐ axis of the graph represents the utility or consumer acceptance.
The higher the utility, the more preferred the product is by consumers.
Figure 4: Example of a consumer model from the JMP software.
The y ‐ axis shows the utility or consumer acceptance while the x ‐ axis shows the different levels of benefit.
Each level can be adjusted independently and will affect the steepness of the curves.
The higher the utility, the more preferred the product by consumers.
When observing the curvature of the plots in Figure 4, it can be seen that the effect of each of the attribute performances is not always linear and symmetric.
This confirms the proposals made by
Mittal and Matzler that the effect of each attribute on WPI is not linear and symmetric but can be asymmetric and non ‐ linear.
Therefore, the Kano model will be used to analyse the results of the conjoint model.
This will be explained next.
In order to analyse the graphs of the different consumer models, Kano’s two ‐ dimensional quality model is used.
The Kano model is an effective tool for categorizing product benefits according to their effect on consumer acceptance (Chen and Chuang 2008).
Researchers have believed in the past that the consumer satisfaction is proportional to the level of benefit performance (Chen 2012).
However, Kano revealed that there exist a non ‐ linear asymmetrical relationship between satisfaction and performance (Kano, Seraku et al.
1984).
Based on the Kano classification a valuable guidance in trade ‐ offs can be offered in the product development stage.
In this case, the Kano model consists of five dimensions (4 benefit areas and price).
Each of these dimensions can be classified based on their relationship between customer satisfaction and product criterion.
These classifications are shown in Figure 5 and are described as (Chen and Chuang 2008):
1) Must ‐ haves: customers become dissatisfied when the benefit is not present but satisfaction is not much increased when benefit is highly present.
2) Linear satisfiers: customer satisfaction is a linear function of benefit level presence.
High benefit levels result in high customer satisfaction and vice versa.
3) Delighters: customer satisfaction increases super linear with increasing attribute performance.
When the attribute is not there, customer satisfaction will hardly decrease.
4) Indifferent: the presence of absence of the benefit attribute has hardly any effect on customer satisfaction.
5) Reverse quality: customer satisfaction decreases when benefit is present and increase when absent.
‐ 32 ‐

Research Methods
Each of the five product attributes can be characterized using the Kano model.
This reveals valuable information on which attributes are important for consumers and which effect each attribute has on consumer acceptance.
Before the Kano model can be used to classify each attribute, the ideal product in the right price category must be specified for each consumer group, meaning: for every segment or group of consumers, the ideal distribution of attribute levels must be established resulting in the highest utility or consumer acceptance in the model.
The procedure for extracting the ideal product from the model is explained below.
Figure 5: Kano’s two ‐ dimensional quality model and it’s characterization of the different benefits (Chen 2012).
Because two ‐ way interactions are incorporated into the consumer model, this means that the shape of the curve is dependent on the levels set for each benefit attribute.
First, the price level is set to the right level because the consumer satisfaction for that particular product is modelled.
In reality it is impossible to offer high levels of each benefit at low prices or no benefit at all at high prices.
To simulate reality it is decided that at a Tier 2 price level, in total 8 “stars” can be divided among the four benefit areas.
In order to find the product with 8 stars which gives the highest consumer preference the “stars” are divided each one after the other.
Each time the “star” is given to the benefit area with the steepest curve or highest utility increase.
This process is shown in Figure 6.
This process can be seen as giving the consumer a coin and asking her the question where she would invest this coin.
Based on , her first answer will be to invest in cleaning.
The second coin that is given will be invested in whiteness and so on.
This yields the most preferred product according to the consumer.
Applying this method, the most preferred product in the particular price category is specified for the strategic target, the segments within the strategic target and the different Tier groups within the strategic target.
The next step is to identify each curve according to Kano’s model.
This will be done in the next chapter.

Research Methods
Figure 6: Example of how the ideal Tier 2 product is found.
In the first picture it can be seen that attribute 2 gives the highest utility increase.
Therefore, this benefit attribute is set from level 1 to level 2.
In total 5 “stars” are divided among the four benefit areas.
Then first the price will increase as an investment of 6 “stars” is too expensive at a Tier 3 price level.
Next, attribute 1 gives the biggest utility increase which means that the next “star” will be given to the attribute 1 benefit.
This goes on until 8 stars are divided among the four benefit areas.
4.2
Operationalization and Measurement Variables
The operationalization of the different variables in the theoretical framework is an important aspect of this research as it indicates how the variables should be measured.
Therefore, this section will focus on how to operationalize the different variables of the theoretical framework and how to measure them in order to answer the research questions.
The most important (dependent) variable is the consumer acceptance or weighted purchase intent.
This affinity can be described as the consumer experience of the product.
Therefore, overall rating of the product is an important aspect to operationalize the WPI.
Furthermore, the product sales are an important way to check the WPI.
The overall rating also has to be operationalized in order to measure it.
The WPI is operationalized by asking the consumer the multiple ‐ choice question “Would you buy this product?” on which the consumer can answer “Definitely would buy, Probably would buy,…., Definitely would not buy” .
The
WPI is then calculated by looking at the percentage of people that answered this question with
“Definitely would buy” .
The OAR is operationalized by asking the consumer the question “How would you rate this product?” which can be answered by “ Excellent (5), Very Good (4),…, Poor (1)” .
The OAR is then calculated by looking at the average after use for overall rating.
From these answers, an average can be calculated representing the average after use value for price/money.

Research Methods
To conclude the methods used in this research; both qualitative and quantitative methods will be used to gather information on the different consumer segments.
The qualitative methods will be used to develop an interface for the quantitative test and to further probe on the quantitative observations.
Both the conjoint and Maxdiff test will be combined in a quantitative virtual product prototyping test.
Both tests need to be designed using the design of experiment approach and qualitative data from the consumer lounge.
The Maxdiff test will be analysed using the Sawtooth software whereas the conjoint test will be analysed using the JMP software and the Kano model.

Data Analysis
This chapter will summarize the information gained from the different qualitative and quantitative tests and interviews.
First, the qualitative results of the interface development will be discussed.
This is followed by the analysis of the quantitative Maxdiff results and the quantitative conjoint results.
The next chapter will contain a discussion on these data analysis.
5.1
Interface Development
Unfortunately, there was no readymade conjoint and Maxdiff interface available.
Therefore, the consumer lounge was used to select the ideal benefit vectors and to develop an easy interpretable interface.
The objective was to design an interface which could be used by consumers without further help of other people.
5.1.1
Maxdiff Interface
For the Maxdiff test, 32 benefit statements in 6 different categories were developed using feedback from consumers in the consumer lounge.
The categories for the benefit statements are cleaning, whiteness, skin protection, care, simplification and freshness.
These categories were only used for internal use and some statements can belong to different categories.
It was noticed that, during the qualitative interviews, illustrations help consumers to understand the specific benefit statements.
Therefore, each of the statements was accompanied by an illustration in order to help consumers understand the benefit statement.
Different illustrations were shown to consumers and the best illustrations were selected which can be found in Appendix 4.
However, the consumer should focus on the statement itself and not on the illustration as the illustration can bias the consumer.
The illustration is only intended for clarification of the statement.
Therefore, the benefit statement is placed in a large font while the illustration is small.
Figure 7 shows two examples of benefit statements with their illustrations.
Due to these measures, the consumers in the consumer lounge indicated that they hardly focus on the illustrations anymore while the benefit statements were clearly understood.
To avoid bias all benefit statement should be pictured on the same screen without scrolling up/down or sideways.
The final Maxdiff interface can be found in Appendix 5.

Data Analysis
5.1.2
Conjoint Interface
The final interface design of the conjoint test was developed based on qualitative consumer interviews in the consumer lounge and can be found in Appendix 6.
During this qualitative research several conjoint interfaces were shown to consumers which can be found in Appendix 7.
These were used to receive feedback from consumers.
Based on this feedback, the following learnings were achieved:
Use visuals instead of wordings: Consumers indicated that wordings work too polarizing.
When wordings have to be translated to another language, the new translation could bias consumers.
This is the case when talking about benefit attributes such as “Care” which have multiple meanings and different translations.
Scales using numbers are considered to be too mathematical and too difficult to read.
This results in a loss of overview where consumers cannot compare the different products efficiently.
Instead, use visuals in order to avoid misunderstanding due to illiteracy
and dyscalculia.
Visuals using bars were positively accepted by the consumers but to be found less catchy than icons.
The use of smileys was not accepted as these were not distinctive enough making it too difficult for consumers to compare.
Emphasize pricing level: Consumers tend to focus only on their benefit area of interest and thereby forgetting to pay attention to the price level of the prototype.
Every consumer has his/her own preference of benefit attribute which creates the tendency to choose the product that is best in this attribute.
In order to avoid this, the price should be indicated by both illustrations and wordings and should be mentioned at the top of every prototype.
In addition, the question itself should state that consumers have to focus on both price level and benefit attributes.
Use equally conspicuous visuals: The icons and border lines used for the scale should be similar in character and equally conspicuous.
When one of the icons is more conspicuous (for example the black stain for cleaning), it will draw the consumer’s attention and thereby biasing the consumer’s choice.
White icons are to be avoided as these icons are unnoticed by consumers.
Avoid colour differences in borders as this will draw the attention of the consumer towards this product prototype.
Use a three ‐ star instead of a four/five ‐ star rating level: Consumers prefer a three ‐ star rating level instead of a four/five ‐ star rating level.
The three ‐ star rating interface (low ‐ medium ‐ high) gives the consumer enough freedom to choose between the different levels, maintains the overview for the consumer to compare the different prototypes and simplifies the DOX design for the conjoint test.
Consumers don’t see any added benefit of having a four ‐ or five ‐ star rating system.
‐ 38 ‐
5.
Data Analysis
Get consumers in the right mindset: In order to get the consumer in the right mindset, an introduction should be given where is explained that the virtual products are tested by a technical institute on four benefit levels using a three ‐ star rating system.
The four benefit attributes should be explained as this is the first time the consumer is confronted with these attributes.
After this introduction, the interface will be explained guiding the consumer through the different areas of the interface.
This is followed by an example “solution” in which a fictive person explains her motivation to choose one of the different prototypes.
The consumer may or may not agree with this example question but the main purpose is to use this as an illustration of how to approach the question.
This approach allowed consumers in the consumer lounge to use the interface independently without extra clarification or help.
In order to avoid bias the brands will not be displayed on screen.
5.2
Maxdiff Analysis
The results of the Maxdiff test can be summarized in a top ranking of the benefit statements.
Each benefit statement has an Average Score assigned which, when added together, will sum up to 100.
The higher the Average score, the more preferred the benefit statement by consumers.
The average of the Average Score is 3.1
as there are 32 benefit statements.
Statements with higher scores can be seen as delighters while statements lower than this value are less preferred by consumers.
The Probability of Choice is the probability that the statement is chosen when shown with five other statements on screen.
The higher the Probability of Choice, the more preferred the benefit statement is by consumers.
To calculate both numbers the Hierarchical Bayes method is applied to the data.

To see whether these benefit preferences can be confirmed, the data of the conjoint test can be used.

The conjoint results can be analysed in two ways: using the Sawtooth Software and using the JMP software.
Because both methods show different relevant conclusions both methods will be covered in this section.

5.3.2
Model Based Conjoint Analysis
The JMP software can be used to build a model from the conjoint data.
When the sample is large enough (i.e.
> 100 consumers), the software is able to predict consumer acceptance according to different benefit levels and the price of the product.
In chapter 5 it was explained that the relationship between a benefit attribute and consumer acceptance might not be linear and symmetric.
Therefore, the Kano model will be used to analyse the different benefit attributes and its relationship to consumer acceptance.
The graphs discussed below show the ideal product derived by the method explained in the previous chapter.

Discussion
In this chapter the results from the previous chapter will be discussed.
The observations from both the Maxdiff and the Conjoint test will be combined to investigate whether they correlate with the existing knowledge presented in the first chapter and whether there are new observations which change the way of operation.
Furthermore, the new approach of using the conjoint together with the Maxdiff will be discussed including its application in future projects.
6.1
New methodological Approach
This research reports the first combination of a Maxdiff test together with a conjoint test.
The goal was to combine these two tests together in a virtual prototyping test to leverage knowledge on the consumer preference of a laundry product (i.e.
question 1).
There were two objectives with combining these two test methodologies: the first objective was to develop an interface which could be used independently by consumers without help.
The second objective was to get a full picture of the benefit space and the trade ‐ offs made by consumers within this benefit space.
The literature study pointed out that the attribute ‐ based conjoint analysis is a good methodology to involve consumers in the development of new products by providing a better understanding of customer trade ‐ offs on multiple product attributes and price.
Question 1: What is the ideal test interface for the virtual prototyping test to leverage the knowledge on consumer preference and product trade ‐ offs?
From the qualitative data presented in the previous chapter it becomes clear that consumers prefer visuals in the conjoint test supported by wordings.
Wyer et al.
presented a research on the role of visuals in communicating verbal information (Bagozzi 2008).
He demonstrates that people spontaneously visualize verbal statements at the time they read the statement and can relate these visualizations back to the phrases.
However, he also demonstrated that consumers triggered by only visualizations cannot relate these back to phrases or specific statements (Wyer, Adval et al.
2002).
These observations are also confirmed by Dahan et al.
(Dahan and Srinivasan 2000).
The qualitative data from the previous chapter is in line with these observations.
Using visuals in combination with wordings helps consumers to get a better understanding on the topic.
Especially in the Maxdiff test, it helps consumers to get a better understanding on the meaning of the benefit statement.
Without an illustration, the consumer will read the benefit statement and make a visualization themselves which might be wrong.
Furthermore, the qualitative data shows that the number of discretization in the different benefit areas of the conjoint test should not be too large.
Consumers in the qualitative tests indicate that 3 levels of discretization and four benefit areas are enough to make a grounded choice.
More levels of discretization confuse consumers and make them lose the overview of the question and the choices they can make.
Research has shown that the larger the number of benefit areas in a conjoint test, the larger the complexity of the test and the more difficult for consumers to make a decent choice
‐ 41 ‐
6.
Discussion among the prototypes (Zhu and Timmermans 2010).
This corresponds with the observations made in this research.
Based on the data from the previous chapter and feedback from the agency that placed the test in
Russia, it can be concluded that consumers are able to use the test without further help.
The foundation of the conjoint test is based on visuals supported by some wordings provided with the right introduction to get the consumer in the right mindset.
This is considered to be the right approach to communicate the different benefit levels of a laundry detergent.
Furthermore, the different responses among the different segments and Tier users indicate that the icons are equally conspicuous and that there is no benefit attribute which draws more attention compared to others.
The different slopes of the price curves indicate that consumers react on the price differences of the prototypes.
This shows that using both numbers and icons to provide the price of the prototype is a good decision.
However, caution should be taken with interpreting the price attribute.
Research has shown that consumers can have a different choice behaviour online compared to their behaviour in a real shop (Degeratu, Rangaswamy et al.
2000).
Consumers are often more price sensitive in the virtual world as they can compare different prices more easily.
Although the agency indicated that the Maxdiff test was no problem for consumers, there are still some doubts on the Maxdiff approach.
The use of illustrations helps consumers to get a better understanding on the benefit statement.
However, the drawback of using illustration is that it can bias consumers.
During this research, there was no time to test if the same results are obtained when illustrations are absent or when illustrations and benefit statements are mixed.
It might be that some illustrations attracted consumers more than others even though the question mentioned to only focus on the statement itself.
According to the analysis of the previous chapter, the second objective was partly met.
The Maxdiff test gives a nice overview of the benefit space whereas the conjoint interface reveals insights in the trade ‐ off behaviour of consumers.
However, the conjoint interface does not show how high the level of each benefit attribute should be.
It gives an indication of “low ‐ medium ‐ high” which is defined by the researcher itself.
The actual level of “low”, “medium” or “high” is not defined in terms of product formulation.
In order to reveal what these levels represent according to consumers, a product placement test can bring a useful outcome.
The different levels of “low ‐ medium ‐ high” can be defined by placing products with different (known) formulations.
In this way, the conjoint model can be coupled with the product placement test to link product formulation with consumer acceptance.
This combination makes it even possible to predict the consumer acceptance of future product formulations.
This brings us at the discussion on how to analyse the results of the conjoint and Maxdiff data (i.e.
question 2).
Despite that more and more software becomes available on analysing these results, there are few options mentioned in literature.
Question 2: How can the results of the conjoint and maximum difference scaling test be used to get a better understanding of consumer wishes?
‐ 42 ‐
6.
Discussion
It was decided to use the Design of Experiment approach to select the right samples for the test to make this test as efficient as possible.
This DOX design has shown to be very helpful as the sample size was held as small as possible while the results are still statistically significant.
Also the Kano model in combination with the JMP software show to be very helpful in analysing the conjoint results.
Using this Kano model and the software, the conjoint data confirms the conclusions drawn by Chen (2012) and Chen & Chuang (2008) who state that the relationship between product attributes and consumer satisfaction is not necessarily linear and symmetric.
The graphs from the different conjoint models often show non ‐ linear and asymmetric behaviour.
Therefore, the use of the Kano model is a welcome outcome which helps to identify the key product attributes for each consumer group.
The graphs were classified by a manual procedure which can cause some bias in the analysis.
This could be improved in the future by automating the classification based on the angle between the three points on the graph.
Despite the manual classification method, the Kano model revealed valuable information on the different product attributes which will be discussed in the next section.

As is discussed earlier, the conjoint test reveals which level of performance is needed to delight or satisfy consumers.
However, these levels are not specified yet.
The three levels need to be specified in the formulation of the detergent.
A product placement test can be used to specify the three performance levels in the four benefit attributes and how these levels relate back to the laundry detergent formulation.
Unfortunately, the placement of the test is not part of this research due to time limitations.

Conclusion
Due to the opening of the Central and Eastern European borders, many multinational companies see opportunities for their products in these regions.
However, these markets are not similar to the markets they usually operate in.
Therefore, local customization strategies are required in order to expand their market share.
Not only cultural bounded products but also non ‐ cultural bounded products such as laundry detergents suffer from this principle.
Companies producing laundry detergents try to develop holistic strategies for these Eastern European countries.
They recognize that local customization strategies of marketing are needed and a better understanding of specific consumer preferences is required.
The aim of this research was to find out how FMCG companies can perform an effective market research to investigate what excites consumers most in a laundry detergent product and what trade ‐ offs are made by consumers.
A quantitative research method was developed for the Russian laundry detergent market.
This research method used a combination of two concepts in a so ‐ called virtual prototyping test; the maximum difference scaling concept and the conjoint concept.
The combination of these two methodologies has never been seen before but can reveal valuable information on trade ‐ offs made in different benefit vector areas.
This virtual prototyping test was performed during a case study for the company Procter & Gamble with the main focus on their laundry detergent brand.
Consumers prefer a virtual prototyping test interface which makes use of visuals.
Illustrations can bias consumers but the test data show that equally conspicuous icons were used where none of the icons drew particular attention.
Too many discretization levels make the test too complicated and distracts consumers.
They can overlook some of the product attributes and thereby make a non ‐ informed choice.
However, the price curves were not flat which indicates that consumer took this product attribute into consideration when choosing their ideal prototype.
Furthermore, illustrations helped consumers to understand the benefit statements of the Maxdiff test resulting in a clear and distinctive rank ‐ ordering of benefit statements.
The conjoint models confirm the existence of a non ‐ linear and asymmetric relationship between product attributes and consumer acceptance.
The Kano model was thus a helpful model to identify the different characteristics of the product attributes to define a local customized product strategy.
Concluding, this research has shown that a combination of a conjoint and a Maxdiff test can reveal important information on trade ‐ off behaviour between price and product benefits.
A clear interface was developed which enabled consumers to do the test without further help.
The case study demonstrated that the virtual prototyping test helped to sharpen the company’s strategy for their brand and to steer product modifications and formulations in the right direction.

Recommendations and Limitations
Due to time limitations of this research, there are still some aspects that need more clarifications and work.
This chapter gives an overview of the recommendations for further improvement of the virtual product prototyping test and will provide recommendations on how the company can improve their laundry detergent brand to increase market share.
Furthermore, the limitations of this research will be discussed.
This research shows the first virtual prototyping test combining a conjoint and Maxdiff test.
It illustrates that it is a powerful combination to explore what product attributes most excite consumers and which trade ‐ offs are made by consumers.
In the field of research, this thesis report contributes on four areas.
First, this research produced an interface which can be reapplied in different markets for different types of products.
In most cases, the interface needs small adjustments in the selection of benefit areas which can then be tested with a small test panel.
The interface can even be used on an internet panel to increase speed ‐ to ‐ market development.
Second, this research illustrates the use of the Kano model and the different software possibilities to analyse the data from the virtual prototyping test.
The data from the virtual prototyping test confirms the non ‐ linear behaviour of consumer benefit preference.
And last, the case study presented in this research shows the usefulness of a virtual prototyping test in developing a localized customization strategy for FMCG companies.
However, this research was done for a company and there are therefore some scientific limitations to the results presented in this research.
The main limitation of this research is its focus on the
Russian market and its specialization on the laundry detergent products.
The test interface has been designed with the Russian consumer in mind.
Therefore, wide applications for this interface in other countries and markets are not granted.
Furthermore, the results presented in this study are based on a small segment of the total market.
Only consumers within the strategic target were recruited which limits the wide application of this test interface.
Therefore, the recommendations for improving the interface are as follow:
Check the benefit statements in an internet panel using qualitative questionnaires.
As is discussed earlier, the benefit statements were placed in combination with illustrations which can cause bias among consumers and their preferences.
Therefore, testing the benefit statements without any illustrations can reveal whether the use of illustrations resulted in biased data.
Another possibility is to mix the benefit statements and illustrations to see whether the same ranking is obtained.
The conjoint test shows which level of each benefit attribute should be present in the laundry detergent.
However, the test does not reveal what each attribute level represents.
Therefore, the virtual prototyping test can be expanded by placing a product placement test.
The virtual prototyping test highlighted which benefit areas are most appealing and which levels should be maintained in the product to satisfy the consumers.
However, these
‐ 47 ‐
8.
Recommendations and Limitations levels were characterized as low, medium and high.
A product placement test can link these three levels to the product formulation of a laundry detergent.
In this way, it will be possible to tell what the performance of the detergent should be in terms of chemical formulation to satisfy consumers.
A virtual prototyping test is an ideal test to be placed on an internet panel.
The current interface has been designed such that consumers can answer the different questions without further help.
However, the current test has not been placed on an internet panel yet.
The test was performed at a central location in Russia where help was available when respondents had questions.
Placing the current virtual prototyping test on the internet panel can expose whether the same results are obtained.
If the same results are obtained, the test can be used in future projects on the internet panel which saves money (no agency required) and saves time (results from internet panel are often available within a week).
In this way, companies will be able to innovate fast and accurate with the help of consumers.
Besides these recommendations to improve the virtual prototyping test design, there are also some recommendations related to the case study.
These are some recommendations for the company to improve their brand position in the market:

Cleaning
Surfactants are the most important ingredients in a detergent.
They contribute for almost 35% to the detergents performance and make up between 10% and 42% of the detergent formula.
The type of surfactant determines the overall cleaning performance of a laundry detergent.
By adjusting the type of surfactant (positively or negatively charged), a laundry detergent can produce more foam, improve the solubility of oil and dirt in water or reduce detergent deactivation in hard water.
Builders make up around 1 ‐ 10% of a detergents formula.
The hardness of the water can harm some ingredients in the laundry detergent.
Therefore, the main function for a builder is to capture free water hardness ions (Ca
2+
, Mg
2+
, etc.) in order to avoid deactivation of the laundry detergent.

Bleach acts as a soil and stain remover and affects the whiteness experience of a detergent.
It attacks soil chemically and thereby breaking it down into smaller particles to increase the solubility of dirt and stains.
Bleach can work during the laundry process or afterwards when activated by sunlight (UV) depending on the consumer needs and drying habits of the region.
Buffers are molecules that bring some alkalinity to the solution to stabilize the ingredients and in the same time control the product alkalinity.
Chemicals used for buffers are NaOH, MEA and Boric acid.
Polymers are molecules that have different functions within a detergent.
They make sure that dye from coloured clothes is captured and cannot be transferred to other clothes; they decrease colour fading and increase colour care.
Polymers also make sure that soils cannot redeposit on other clothes and it makes sure that soil releases much easier from the fabric to remove tough stains (stain removal).
These molecules remove heavy metal ions like Fe
3+
, Mn
2+
, Al
3+
, etc.
Many colours of stains originate from pigments which structure is a stable complex based on metal ions.
The chelants remove this metal ion and thereby weaken the structure of the stain and lighten the colour of any residual stain.
Furthermore, it stops bleach decomposition during storage of the detergent.
These consist of positively charged molecules that bind strongly to the negatively charged surface of cotton.
The result is a soft and greasy material which reduces the friction between fibres and yarns.
Fibres are covered by an active layer delivering a lubricating effect on the fibre surface and thereby increase the softness experience.
Enzymes are proteins made of millions of amino acids.
Each enzyme has its own unique function in the detergent.
Even a slight change in the sequence of amino acids alters the shape and function of the enzyme.
The different enzymes used in a detergent are:
‐ Protease: For protein containing soils like blood, grass etc.
‐ Amylase: For sugar/starch containing soils like chocolate
‐ Mananase: For guar gum containing food like choco ice ‐ cream
‐ XyloGlucanase: For particulate soils like clay
‐ Lipase: For fatty esters like sebum and greasy food
‐ Cellulase: For cellulose bonds like fibres
These are molecules enhancing the whiteness of clothes by absorbing daylight and reflecting white light.
The perfume of a laundry detergent is made of 10 to 200 raw materials or sub ‐ components.
The role of perfume in a laundry detergent is to mask unattractive base odours, provide freshness benefit across consumer touch point and reinforce perceptions of other product benefits like cleaning and softness.
There are three moments when consumers experience the perfume of a detergent:
1) On wet garments
2) On dry garments
3) In the box/package
