Brand Concept Map: A New Way of Segmenting the Market. Céline Brandt, HEC-Ulg. Abstract Brand maps, or graphical representations of brand associations’ networks are particularly useful when trying to understand the links and relations between brand attributes. These brand associations can be based on particular features, logos and usage situations. The networks show the value of the brand to consumers. Thus, it is essential for marketing managers to be aware of the nature and structure of associations for their brand. In this paper, we first present the different methods used to build brand maps and compare them with a new methodology developed by Roedder John et al. (2005), namely: Brand Concept Maps (BCM). This is followed by two empirical studies. In the first study, we apply the BCM methodology to identify the network of brand associations to Lipton Ice Tea. “Nature”, “fruits”, “thirst-quenching”, “freshness”, “sun”, “pleasure” and “terrace” are seven of the ten core brand attributes present in the brand map. These attributes correspond to the European vision of Lipton Ice Tea, i.e. a healthy beverage, with the benefits of tea and considered as a juice rather than as a soft drink. But “sugar”, “contemporary” and “soft drink” are three core associations which do not correspond to the classical perception of Ice Tea. Furthermore some negative attributes like “sugar”, “marketing” and “obesity” are also present in the brand map. In the second study, we aggregated data from individual brand maps to reveal segments with different brand perceptions. We propose a market segmentation, based on similar brand perceptions (or brand maps). Subsequently, we translated the sets of brand perceptions in effective segments through the use of demographic and behavioral variables. Using cluster analysis, we found 6 different clusters: ”After sport”, “sunny”, “sweet and expensive”, “fruit juice”, “quality at any time” and “light and healthy”. The goal was to identify which of the subgroups have a perception that is inconsistent with the European perception of Ice Tea. While the attribute “soft drink” is perceived by all the clusters, non-consumers and casual consumers consider ice tea as an aggressively marketed product, being full of sugar In terms of managerial implications, BCM will allow marketers to define the core brand associations and distinguish between vital associations and attributes that could be managed in order to transform the brand image. Second, managers will be able to differentiate between the perceptions of the different segments and decide which segment to target in order to harmonize or modify the brand image. 2 I. Introduction Most cognitive psychologist believe that information is organized as a network in consumer memory (Collins and Loftus 1975, Collins and Quillian 1969, Tversky 1977). Those networks are commonly called associative networks. They consist of storage units filled with associations and associative links (Solomon 2006, p101). A graphical representation of a concept and its associations is called a concept map. A brand map identifies essential brand associations, but also conveys how these attributes are connected to the brand and to each other (Roedder John et al. 2005). Using different research methodologies, brand maps can be developed as a visual representation of these associative networks which are present in our memory. Brand associations can have different characteristics: Consumers associate a brand with particular attributes or features, logos, usage situations, and so on. Some of these attributes are conscious, and some are subconscious. This association network shows the brand’s uniqueness and the unique value of the brand to consumers (Aaker 1996). Because of the links to brand equity, it is essential for marketing managers to be aware of the nature and structure of associations for their brand (Henderson et al. 1998). Ideally, managers should be able to produce brand maps containing the important brand associations and the links betweens these associations. It would help them understand how the brand is perceived by the consumer in general, or by segment, how this perception corresponds to the brand positioning and thus how to adapt the integrated communication. Concept maps have been applied to a variety of areas. In the 1990s, several studies linking concept maps to marketing issues appeared (Carbonara and Scozzi 2006, Elliot et al. 2003, Higie Coulter and Zaltman 1994, MacKay and Easley 1996). Brand concepts maps have first been analyzed in a qualitative manner with a focus on the individual perceptions in order to 3 increase the likelihood that the full variety of brand associations in a respondent’s memory will be evoked. More recently, several studies have included quantitative analyses of brand concept maps. Those studies capture the brand image using measures of centrality, cohesion, position, density and structural equivalence (Henderson et al. 1998) or highlight the brand’s core identity using an aggregation procedure (Roedder John et al. 2005). These quantitative methods and their applications to branding are still in their infancy. This paper proposes an application of the Brand Concept Mapping (BCM) method to a branded consumer good and the use of this quantitative technique to segment the market based on brand perception. The Brand Concept Mapping approach has significant implications for researchers, as well as managers. First, BCM not only allows the use of past research to simplify the elicitation stage, but it also allows to aggregate the individual brand maps, which was not possible with the classical consensus maps. In light of these issues, the goals of our first study is to better determine the usefulness of BCM for branding research by replicating the methodology used by Roedder John et al. (2005) and checking for validity, but also by applying the tool to another product (good instead of service) and by improving the elicitation stage using the Zaltman metaphor elicitation technique, or ZMET (Zaltman and Coulter 1995).In the second study, we use the tool for a new application. We propose to cluster the individual brand maps in order to segment the market in terms of brand perception. Then, we will translate the sets of brand perceptions in effective segments through the use of demographic and behavioral variables. Second, BCM is a mapping method that allows managers to rely on past research to define the brand attributes before building the individual and aggregate brand maps. As a result, managers are able to define the core brand associations (proximity and links), compare them with the brand positioning and assess the efficacy of the communication campaign. One can distinguish between vital associations and attributes that could be changed in order to 4 transform the brand image. Also, managers will be able to differentiate the perceptions of the different segments and decide which elements of the integrated marketing communication mix (IMC) have to be modified in order to correct the brand image problem or in order to improve the synergy. BCM will also help managers in identifying which segment to target in order to harmonize or to modify the brand image. VOIR UNILEVER Our research consists of two studies. The first study examines the perception of Ice Tea in the French part of Belgium (Wallonia). and how the Wallonia brand concept map differs from the European Ice Tea perception? The second study considers how individual consumer characteristics (e.g. gender, age, net income) influence the Ice Tea brand perception and how behavioral characteristics of the consumers (e.g. consumer and non consumer) will influence the Ice Tea brand perception? We have structured this paper as follows. First the relevant literature on segmentation and concept mapping is briefly reviewed. Next, we present the model used for our study and compare it with other brand maps elicitation models. Subsequently, the strengths and weaknesses of the different methods are identified. We then present two empirical studies including the issue, the methodology, the collecting procedure and the coding method. We conclude with a new approach to segmentation and a general discussion. 5 II. Literature Review Collins and Quillian (1969) were the first to develop a model of knowledge organization in long-term memory. They concluded that concepts are linked to nodes that represent the concept properties. They also developed the idea that concepts are organized into a hierarchy in consumer memory and that properties of concepts are stored at the highest possible level in the hierarchy and not re-represented at lower levels. Collins and Loftus (1975) proposed another model of information storage which is still used today for marketing applications. It assumes that properties can be represented several times in consumer memory and that information is not organized hierarchically. This model has been used to develop concept mapping techniques, in different areas of interest. When using concept maps, we assume that the arrangement of the information on the page reveals the inherent relationships represented in a person’s mind (Joiner 1998). Concepts maps are frequently used in educational and counseling research (Comeau and Hiebert 1991, Goodyear et al. 2005, Martin 1985, Mc Clure et al. 1999, Novak and Gowin 1984, Xiufeng 2004). It has also been applied to social psychology (Lord and Desforges 1994). Recently, (Schuck and Liddle 2004) applied the concept mapping technique to human resources management, particularly to the experience of women in management positions. In the 1990s, the technique was first applied to the marketing area with a focus on the product and later on brands. MacKay and Easley (1996) showed international differences in product perception using concept maps. Elliot et al. (2003) used concept mapping techniques to assist product resourcing decisions. Carbonara and Scozzi (2006) used concept maps to investigate the problem of new product development process. Focusing on branding, Dobni and Zinkhan (1990) summarized the different techniques that have been used to capture the brand image, starting with the individual dimension proposed by Pohlman and Mudd (1973). Dolich (1969) investigated a single measure for overall brand image while Boivin (1986) developed isolated 6 measures or measures relative to the competition. Bird et al. (1970) measure brand image as a function of brand usage and brand conspicuousness while Green and Devita (1977) developed measures based on discriminating attributes. Two categories of techniques have been used to create brand maps in various ways, namely: consumer mapping and network analysis systems. In the first category, brand associations are elicited from consumers, who are then asked to construct networks that show links between associations and the brand as well as links among associations. Finally individual brand maps are aggregated into a consensus brand map. When using network analysis systems, brand associations, obtained from the elicitation stage with customers, are used, followed by analytical methods, to discover the network of brand associations (measures of centrality, cohesion, position, density and structural equivalence). Two qualitative consumer mapping techniques have been utilized in the area of branding. Higie Coulter and Zaltman (1994) applied the Zaltman metaphor elicitation technique (ZMET) to the brand. ZMET is a research tool that uses visual and sensory image, assuming that 80% of the human communication is nonverbal. The ZMET is designed to” understand the cognitive structures, or mental models, that cause a feeling of personal relevance” (Christensen and Olson 2002). This method contains three steps: the eliciting stage, the mapping stage and the aggregation stage. During the elicitation stage, 15 persons are recruited and the topic is introduced. Then, participants collect 12 pictures about the topic to prepare a two-hour interviews that will take place 10 days later. During this interview, participants will be asked to tell stories about the pictures and to sort the pictures. As a result, constructs will be elicitated using the repertory grid method and laddering process. During the mapping stage, respondents are asked to create a map illustrating the connections among important constructs. Finally, during the aggregation stage, data are codified and constructs 7 are chosen in order to build the final map, regarding how frequently they are mentioned. The primary strength of ZMET is the ability to elicit conscious and unconscious attributes, if these are unknown. But this process is very labour intensive, especially the elicitation stage. Interviewers must be specially trained to cognitive psychology and neuroscience, while respondents must be willing to participate to two interview sessions and prepare pictures for them. This method is well suited to situations where limited data exists. But, if prior research exists regarding the brand attributes, and if the goal is to understand the individual brand maps structures, this methodology is not very useful. Joiner (1998) examined whether the concept map methodology could be used with marketing-related stimuli to elicit salient concepts. He also examined the stability and reliability of brand associations. Compared to the ZMET, traditional concept mapping techniques are easier to administer, but they focus more on conscious evaluation. Up to this point, concepts maps have always been analyzed in an qualitative perspective with a focus on the individual perceptions, in order to increase the likelihood that “the full variety of brand associations in a respondent’s memory will be evoked” (Joiner 1998, p312). The traditional concept mapping methodology does not allow aggregating the brand association networks. In order to solve this problem, new quantitative methodologies have been developed. Henderson et al.(1998) developed a quantitative tool to capture the brand image using social network analysis (measures of centrality, cohesion, position, density and structural equivalence). Klein Reesink (2004) also used social network analysis to collect brand knowledge in a quantitative way, using an internet experiment. But traditional concept mapping methods and social network analysis are very intensive in the elicitation stage due to the attributes elicitation from the individual consumers. Roedder John et al. (2005), pioneered a quantitative consumer mapping technique allowing the aggregation stage as a result of a more structured elicitation stage. This mapping method 8 has less labor-intensive processes in the elicitation and aggregation stage because of the use of prior brand research. Procedures do not require specialized expertise and training for interviewers.. The main weakness of the method is that it focuses on the conscious part of the brand evaluation, as opposed to ZMET which uncovers certain unconscious attributes through the use of pictures description and specially trained interviewers. ZMET and other projection techniques are used to reveal private feelings, irrationality, illogical behavior and repressed attitudes, which cannot be noticed through the use of classical interview techniques (Pellemans 1999) INSERT FIGURE 1 In the second study, we will use this method to segment the market in terms of brand perception. Several authors (Buchta et al. 2000, Gensch 1978, Gonzales-Arce 1975, MacKay and Easley 1996) investigated market segmentation in terms of brand perception. However most of them (Buchta et al. 2000, Gensch 1978, Gonzales-Arce 1975) focus on the comparison between several brands, whereas BCM focuses on a single brand: Gonzales-Arce (1975) used likert-type scaling and group interviews to build a consumer preference study for several brands, Gensch (1978) highlight image-measurement differences after the evaluation of 17 attributes of several brands in focus groups, Buchta et al. (2000) used perception-based marketing segmentation to identify perceptual profiles by representing several products on the same map. MacKay and Easley (1996) compared the product perception on two different markets by using MDS. Compared to MDS, BCM allows the representation of various attributes, showing the strength of the links and the proximity of the associations. This research attempts to answer the following questions: What is the perception of Ice Tea in Wallonia? How is the Wallonia Brand Concept Map different from the European Ice Tea perception? Indeed, the Belgian market is an unusual market for Lipton Ice Tea and its maker (Unilever). Since most of the European countries perceive Lipton Ice Tea as a healthy and a 9 100% natural drink that can be compared to a juice, Belgian consumers and non-consumers still perceive the product as a sweet soft drink linked to sport and energy. The goal of Unilever is to obtain a uniform brand image which is consistent for the whole Europe. INSERT FIGURE 2 Second, using codified data, we will cluster the respondents in terms of brand perceptions and analyze the differences between clusters using ANOVA tests and contingency tables. This second study will allow us to analyze the characteristics of the different clusters in terms of demographic and behavioral variables. Based on these findings, we will be able to find which segments have a biased brand perception and which communication decisions have to be taken in order to correct this image problem.

Study 1 Research Design Secondary data and qualitative interviews with brand managers The main goal of the qualitative interviews was to obtain a complete list of brand attributes. In order to achieve it, we first analyzed the past studies ordered by the company, and then we interviewed the product manager about the brand. After this first step, we obtained the following list of attributes: INSERT TABLE 1 ZMET or the qualitative interview with consumers and non-consumers The goal of this qualitative research was to identify additional attributes that could be included in the quantitative approach. Most of the variables had already been elicited in conducting interviews with brand managers (see above). In order to be thorough, we performed in-depth interviews with consumers and non-consumers following the elicitation stage of Zaltman Metaphor Elicitation Technique (ZMET). Visual stimuli, which evoke conscious and unconscious responses, were used. We performed 25 interviews following the ZMET process explained in the literature review. A sample size of 15 respondents is considered sufficient (Zaltman and Coulter 1995). We used the additional attributes to complete the list made with the Lipton Ice Tea brand manager and obtained a final list of 32 attributes. INSERT TABLE 2 Quantitative interviews For this part, we performed 160 face-to-face interviews, using open-ended questions to obtain personal and sensitive answers. Respondents were asked to create their brand maps in four different steps. The first step is the selection and elicitation of brand associations. The interviewer shows a poster containing cards with brand associations (positive and negative) 11 and participants are asked to answer the following unstructured question: “What comes to mind when you think about this brand?” At the beginning of the second step, the interviewer shows another brand concept map to describe the different links (single, double or triple) indicating how strong the associations are. The main goal of the third step is to create the brand concept map for the brand in question, using the cards they have previously selected, a poster containing the brand name as well as simple, double and triple lines to connect the cards. In the last and fourth step, the interviewer asks respondents to write down degree of familiarity, the closeness of the relationship and the prior experiences with the brand. The target population is defined as Belgians living in Wallonia. Taking into account the exploratory nature of the study, we chose a non-probability sampling system. The sex, age, revenue and “consumer-nonconsumer” are the major segmentation variables used by Unilever when segmenting the Ice Tea market in terms of customer needs. In order to underline the different brand perceptions (study 2), we want to have representatives of all the subgroups of the population in our sample, therefore, we will use quota: INSERT TABLE 3 The selection of the respondents will then be made, based on convenience. Codification and aggregation Finally, the individual brand maps have to be codified in order to aggregate them and obtain one single overall brand map for the whole population. Different aggregating measures were developed to build the consensus map. The first two measures tell us if the attribute is “core” in the consumers’ perception of the brand. The first measure is “the frequency of mention” which is calculated by dividing the number of times an attribute has been cited by the total amount of individual maps. The second measure is “the number of interconnections” which counts the number of times the brand association is linked to other associations. The next measures show which of the core associations should be linked directly to the brand. “The 12 frequency of first order mention” measures the number of times an association has been directly linked to the brand. ”The ration of first order mentions” is the frequency of first order mention divided by the frequency of mention. Finally, the type of interconnections, superordinate or subordinate, indicates if most associations linked appear below it (superordinate) or above it (subordinate). Data Analysis In order to build the consensus map, the first step is to identify the core attributes that best describe the brand. In order to achieve this, we used the frequency of mention and the number of interconnections. The 50% cutoff had been chosen to keep the attributes that have been listed by a majority of respondents. This level is consistent with similar 50% cut-off levels in many content study of brand attributes, beliefs and values (Roedder John et al. 2005). If we include the borderline frequencies (>45%), we obtain 10 core brand associations. The goal of the second step is to determine which of the core brand associations must be directly linked to the brand. If the first–order mention is higher than 50% and if the number of superordinate connections is higher than the number of subordinate connections, the attribute can be considered as a first-order attribute. Eight of the 10 core attributes fulfill the conditions to be directly linked to the brand. The third step involves an analysis of the associations’ links in order to find where to place the remaining core brand attributes. Therefore, we examined the frequency of links between associations. Finally, we decided to incorporate non-core brand associations that are frequently linked to core associations. In order to decide which type of link to use for each connection, we take the average type used in the individual brand maps. INSERT FIGURE 4 We notice that most of the core associations correspond to the European perception of Lipton Ice Tea: “nature”, “fruits”, “thirst-quenching”, “freshness”, “sun”, “pleasure” and “terrace”. But “sugar”, “contemporary” and “soft drink” do not correspond to the classical perception of 13 Ice Tea. Indeed, the brand managers want Ice Tea to be considered as a “fruit juice” instead of a “soft drink”. The three attributes with a double links are “thirst-quenching”, “sun” and “terrace”. Those three attributes correspond to the European perception of Lipton Ice Tea. Most of the associations are positive except for the marketing and the sugar, which is directly linked to overweight. Reliability Split-Half Reliability: In order to test the reliability, the individual brand maps are randomly split in two halves and we repeated the aggregation procedure for the two split-half maps. Then we evaluated the degree of consistency between the both consensus maps and thus check if the measures are reliable. The first aggregate brand map has 10 core attributes, while the second one has 9 core attributes. Both aggregate brand maps have 7 attributes in common: “fruits”, “plants”, “freshness”, “thirst-quenching”, “sun”, “soft drink” and “relax”. The two additional core brand attributes in the first consensus map are “lemon” and “marketing”. The two maps have 6 first-link associations, with 3 attributes in common. The two figures have at least a moderate degree of consistency. In order to be more precise, we did a quantitative analysis of split half reliability. If we compare the two brand maps in terms of the presence or absence of each of the possible 32 brand associations, we obtain a significant chi-square indicating a distribution different from what expected (Chi-square=16,725; p=0,000<0.05; N=32) and thus a high correlation between the two brand maps (Contingency coefficient= 0,586). If we compare the two brand maps in terms of the presence or absence of each of the possible 32 brand associations as a first link association, we obtain a significant chi-square (Chi-square=4,734; p=0,030<0.05; N=32) and thus a sufficient correlation between the two brand maps (Contingency coefficient = 0,359). Therefore, the degree of consistency between the two brand maps is high and our measure is reliable. 14 Nomological validity: In order to test the nomological validity, we split the individual brand maps in two categories that should differ in a predictable way (consumers and non-consumers or “best friend”, “casual friend” and “casual acquaintance”), and then we repeated the aggregation procedure for the two or three maps. “Experts typically have knowledge structures that are more complex and highly integrated, which would translate into more brand associations, more brand association links, stronger brand association links and greater hierarchical structure” (Roedder John et al. 2005, p55). The map for the “consumers” group has a more complex structure with more brand associations (the “consumers” consensus map contains 10 core brand attributes and the “nonconsumers” consensus map contains 8 core brand attributes), more interconnections between associations and more double links. INSERT TABLE 4 After having performed a second analysis at the individual level, the calculations confirm that the consumers have brand concept maps with more associations, more first-level associations, more links, more triple and double links and a more hierarchical branching (more second and third-level associations). Therefore, the differences between consumers and non-consumers have been shown clearly, and thus provide proof of the nomological validity. Fournier (1998) described the relationship between a consumer and a brand as a dyadic relationship similar to a relationship between two persons. In order to represent the closeness and the intimacy (Berscheid and Peplau 1983), respondents have been asked to characterize their relationship with Lipton Ice Tea as either “best friend”, “casual friend” or “casual acquaintance”. “Best friend” is the most intimate relationship with personal involvement and affect (Roedder John et al. 2005). The consensus brand maps are expected to be different for these three categories, because the more intimacy consumers have with the product, the more knowledge they have about the product and the more complex the brand map should be regarding the number of 15 associations, the hierarchical structure, the number of links and the number of double and triple links (Roedder John et al. 2005). By comparing the maps, we would conclude that the “best friend” map is the most complex (13 core attributes) followed by the “casual friend” map (10 core attributes) and the “casual acquaintance (9 core attributes). In terms of core brand associations, the results are not as clear. The “best friend” map has eight first-order associations, while the” casual friend” map has seven first-order associations. But the “casual acquaintance” has nine first-order associations. Furthermore, the number of links is smaller for the “best friend maps” than for the two other maps. We find that the “casual friends” include first-order attributes like “sports” or “soft drink”, while the “best friends” do not. The “best friends” and “casual friends” only chose positive associations. Conversely, the “casual acquaintances” also consider Lipton Ice Tea as a beverage with a lot of “sugar” that leads to “obesity”. They also underlined the “marketing” aspect of the brand, which is often perceived negatively. In the second analysis at the individual level, we can conclude that the “best friend” map is the most complex (followed by “casual friends” and “casual acquaintance”) in terms of the number of first-level associations, the total number of links, the number of first-order links and the number of triple links. If we compare the two extreme groups, the total number of beliefs, the number of second and third –level associations and the total number of double links are higher for the best friends. But for these three items, the “casual friends” have the highest values. Finally, regarding the number of second and third order links, as well as the number of single links, the “best friends” have the least complex individual brand maps. To conclude, for most of the figures, the complexity rank is confirmed. For the other items, it is important to 16 underline the small sample of best friends (8) that could have biased the consensus brand map of this category. Discussion Our first study describes the BCM method and proves its usefulness, reliability and validity. As described before, the main advantages of the technique are an effective elicitation stage due to the standardized answers and the possibility to aggregate the results in a consensus brand map. This last benefit was not attainable with the previous concept mapping techniques. Because of this new method, we are able to better understand the Ice Tea general perception, the attributes linked to the brand and the importance of the attributes because of the different links. Regarding the Ice Tea perception, this first study allowed us to identify the main features of the product. “Nature”, “fruits”, “thirst-quenching”, “freshness”, “sun”, “pleasure” and “terrace” are seven of the ten core brand attributes present in the consensus brand map. Furthermore, the three first-order attributes with a double links are “thirst-quenching”, “sun” and “terrace”. These attributes correspond to the European vision of Ice Tea, i.e. a “healthy” beverage, with the benefits of tea and considered as a “juice” rather than as a “soft drink”. But “sugar”, “contemporary” and “soft drink” don’t correspond to the classical perception of Ice Tea. Furthermore some negative attributes like “sugar”, “marketing” and “obesity” are also present in the consensus map. A first nomological validity analysis using two brand maps, one for consumer and one for non-consumers, showed us the differences between the two groups. On the basis of this analysis, we can see that the attributes “marketing” and “sugar” are only identified by non-consumers, while the attribute “contemporary” appears only in the consumers’ consensus map. The nomological validity analysis showed us the different perceptions of Ice Tea based on the buying behavior. A relevant question at this point is: do other variables, for example 17 demographic variables, influence the Ice Tea perception? In particular, do the brand maps differ in terms of core brand attributes for respondents with different ages, income and gender? We will examine these questions in our second study. IV. Study 2 Research Design In order to segment the market based on brand perceptions, we will use cluster analysis to create clusters of individuals who show similar brand perceptions. In order to interpret the clusters, we will perform independent-samples T-tests and profile diagrams. This analysis will allow us to check the different values of the attributes in the clusters. Finally, we will use ANOVA in order to test if the clusters differ in terms of age (metric variable) and we will generate contingency tables to distinguish the differences among clusters in terms of gender, income, consumer/non-consumer and relationship groups (categorical variables). Considering the small sample, we cannot check the validity at the segment level because of a split-sample technique. Data Analysis Cluster Analysis The purpose of cluster analysis is to group objects based on the characteristics they possess. The size of the sample is large enough to represent all of the relevant groups of the population (table 3). We will use Sokal and Sneath 4 as suggested by Everitt et al. (2001) for binary variables. As a cluster method, we will use the “complete linkage method” (or further neighbor). Using the measure of heterogeneity change, profile diagrams and the independent-samples Ttests, we will decide how many clusters to keep in the analysis. By plotting the distance coefficients, we propose to choose the 5 clusters solution (slope variation). We have analysed 18 the 4-clusters solution and the 6-clusters solutions as well in order to avoid losing information. INSERT FIGURE 5 Using profile diagrams and the independent-sample T-tests, we conclude that the clusters that are grouped to switch from 6 to 5 and 5 to 4 clusters are significantly different on several variables. In order to analyze the data as thoroughly as possible, and to avoid losing information, we will analyze the 6-clusters solution. Using the mean-scores, the profile diagrams and the independent-samples T-tests, we will describe the clusters in terms of brand attributes and assign a label to each cluster. INSERT FIGURE 6 First of all, we noticed that the attribute “thirst-quenching” is important for all the clusters. Cluster 1: “After sports” The members of the first cluster consider Ice Tea as a beverage that can be drunk at any time, but especially after sports, or relaxing on a terrace. More than 50% of this group considers Ice Tea as a fresh soft drink linked to (tea) plants. Cluster 2: “Sunny” The second cluster considers Ice Tea as a beverage witch is mostly drunk when the weather is sunny. More than 50% of the members enjoy the freshness and the fruity side of Ice Tea. They also link Ice Tea to a relaxation. Cluster 3: “Sweet and expensive” The third cluster has a negative perception of Ice Tea. This group considers Ice Tea as a soft drink, full of sugar that causes obesity. They also criticize the price of the beverage, the marketing, as well as the presence of aspartame and other additives. More than 50% of this group also considers Ice Tea a contemporary, fresh sparkling soft drink, linked to the sun. Cluster 4: “Fruit Juice” 19 Cluster number 4 considers Ice Tea especially linked to freshness, lemon and other fruits. 70% of the members find it especially linked to (tea) plants, but 50% of the sample considers it as being very sweet. Cluster 5: “Quality at any time” The cluster number 5 considers Ice Tea as a contemporary beverage that can be drunk at any time. This is a quality beverage, but with a risk of becoming overweight when the consumption is high. Most of the members also emphasized the healthy side of Ice Tea, particularly Ice Tea Light. But they also recognized sugar quantity and the high level of marketing. Cluster 6: “Light and healthy” The members of this cluster emphasized the healthy side of Ice Tea, and particularly Lipton Ice Tea Light. They noticed the quality of the beverage, the link with fruits and plants and the energy contribution. More than 50% of this group also recognized the link to sports, freshness, terrace, sun, relaxation, lemon and marketing. Using ANOVA and contingency tables, we will compare average score profiles on behavioral and demographic variables for the clusters in order to profile them. ANOVA and Contingency Tables Age: ANOVA as well as the pairwise Post Hoc tests indicate no significant difference in age between the clusters (sig=0,095>0,05; F=1,917). If we distinguish Lipton Ice Tea’s target market, i.e.people below 40 years old, and the people above 40, we obtain a contingency table with a significant chi-squared test (sig= 0,039<0,05) indicating a systematic association between the two variables. We notice a higher relative proportion of persons below 40 years old in the clusters number 6 and a majority of persons above 40 years old in the cluster number 5. 20 High and low income: Thee chi-square test is not significant (0,489>0,05), we notice the higher relative proportion of the high income in the cluster number 3 and a higher relative proportion of low income in the cluster number 6. Gender: Despite the non-significant chi-square (0,646>0,05), we notice a higher relative proportion of women (0) in the clusters number 3 and 6 and a higher proportion of men in the cluster number 1, 5. Consumers and non-consumers: With a significant chi-square (0,013<0,05) indicating a systematic association between the two variables, we notice a higher relative portion of consumers in the clusters 1 and 2 and a higher relative proportion of non-consumers in the clusters 3 and 5. Best friend, casual friend, casual acquaintance: Despite the non-significant chi-square (0,185>0,05), we notice that the first cluster contains a bigger proportion of members coming from the best friend group and few casual acquaintances. The second cluster contains mainly casual friends and casual acquaintance. The third group contains principally casual acquaintances. The cluster number 4 contains a higher relative proportion of casual acquaintance and the cluster number 6 has a higher relative proportion of best friends. Clusters’ profiles Cluster 1: “After sports”: This group contains principally men who consume Lipton Ice Tea on a regular basis, after sports, and consider it as a “best friend”. Cluster 2: “Sunny”: This cluster contains mainly consumers who drink Lipton Ice Tea on a casual basis, on a terrace when the weather is sunny. Cluster 3: “Sweet and expensive”: This cluster contains mainly women with high income, who don’t consume Lipton Ice Tea and consider it as a casual acquaintance because of advertising. Regarding the attributes listed, we deduce that those women described their opinion about the classic Lipton Ice Tea. 21 Cluster 4: “Fruit juice”: This cluster contains men and women that consider Lipton Ice Tea as a fruit juice (freshness, plants, lemon) and consume it as a casual acquaintance. Cluster 5: “Quality at any time, break”: This cluster contains principally men above 40, who don’t drink Lipton Ice Tea. Cluster 6: “Light and healthy”: This cluster contains mainly women below 40 with a low income, who consider Lipton Ice Tea as being their “best friends”. Regarding the attributes listed, we assume that those women consume Lipton Ice Tea Light. V. Conclusions and implications for brand management Our first study allowed us to identify the main features of the brand. Some of the core attributes of the consensus map are consistent with the European perception of Ice Tea, i.e. a healthy beverage, with the benefits of tea and considered as a juice rather than as a soft drink: “Nature”, “fruits”, “thirst-quenching”, “freshness”, “sun”, “pleasure” and “terrace”. But “sugar”, “contemporary” and “soft drink” are three core associations that do not correspond to the traditional perception of Ice Tea. Furthermore some negative attributes like “sugar”, “marketing” and “obesity” are also present in the consensus map. The goal of the second study was to discover if brand perception changes when the demographic and behavioral variables differ. We also want to identify which of the subgroups have a opinion that is inconsistent with the European perception of Ice Tea. Using cluster analysis, we found 6 different clusters: “After the sport”, “sunny”, “sweet and expensive”, “fruit juice”, “quality at any time” and “light and healthy”. Because of the studies described above, marketing managers are able to see which associations define the brand’s core identity and which associations have to be changed in order to alter the brand image. On the basis of the second empirical study, managers are able to see the distinctive brand perceptions of the different segments and distinguish which brand perceptions are not consistent with the European perception of a 100% natural and healthy drink containing anti-oxidizers: “soft drink”, “sugar”, “marketing” and “contemporary”. 22 We conclude that most of the problematic attributes are perceived by non-consumers or by casual consumers, except for the “soft drink” side which is perceived by almost all respondents. The reason for this “soft drink” image is that most Belgians consume a sparkling Lipton Ice Tea, which is more similar to a soft drink than to a fruit juice. Regarding the other problematic attributes, they are mainly perceived by non-consumers and casual consumers, thus we assume that the product itself and its packaging are consistent with the European positioning. Therefore, the main problem is located on the communication campaign. Indeed, several years ago, Lipton Ice Tea Belgium concentrated the communication campaign on sport. Since most of the drinks dedicated to sport are energy drinks which contain high proportions of sugar, certain people consider Lipton Ice Tea as part of this category. The attribute “marketing” is due to large advertising campaigns by the maker of the product, while the attribute “contemporary” is due to the trendy side of the product and the target market (<39). Thus, the maker of the product should improve the synergy of the integrated marketing communication, correct the sports drink image and enlarge the target market to include older consumers who often worry about products being healthy. 23 References Aaker David.
