ISBN: 978-1-922069-70-2 Life Cycle Cost Management: An Environmental Approach Sevgi Aydin1 and Ferhan Emir Tuncay2 The purpose of this study is to verify the importance of environmental focusing in the life cycle cost (LCC) management. For this purpose, as the first step, differences between traditional cost management and life cycle cost management were determined. Then, cost life cycle and sales life cycle were examined. These are two different aspects of product life cycle perspective and they are used by life cycle cost management. The concept of life cycle was examined from the perspectives of marketing, production and customers. The relationship between these perspectives was determined. The issues of generating profits and reducing the costs which are important in life cycle cost management were mentioned, and life cycle valuation with respect to environmental accounting was explained. JEL Codes: M41 1. Introduction Strategic cost management emphasizes the need for paying attention to and also for executing external focusing and, at the same time, both internal and external connections. In relation to this, life cycle cost management is an approach that forms conceptual framework to ensure the execution of the board's internal and external connections. (Hansen and Mowen, 2006). In traditional cost systems, the costs of products or services are measured in short periods like months or years. While life cycle cost management provides a long term perspective. That is because life cycle cost management is interested in the whole life cycle of a product or a service. Thus, it provides a larger perspective on the product/service cost and profitability. Administrators are expected to handle not only the production costs but also the total costs in a product's whole life cycle (Blocher et.al. 2005). Today, the intense international competition and technological advances are increasing the importance of life cycle cost management for corporations (Dunk, 2004). The differences between the traditional cost management and the life cycle cost management are shown on Table 1 (Erden, 2004). 1 Ass.Prof.Dr. Sevgi AYDIN, Kadir Has University, Applied Science Faculty, Department of Accounting and Financial Management, Turkey, Accounting Discipline, sevgi.aydın@khas.edu.tr. 2 Lecturer Dr. Ferhan EMİR TUNCAY, Kadir Has University, Applied Science Faculty, Department of Accounting and Financial Management, Turkey, Accounting Discipline, ferhanemir.tuncay@khas.edu.tr. 1 Proceedings of 11th International Business and Social Science Research Conference 8 - 9 January, 2015, Crowne Plaza Hotel, Dubai, UAE.

Makes use of life cycle costing. The control of costs is important only The control of costs is important from during the production level. the beginning of the development level. Life cycle costing approach is grounded on the basis of cost and profitability analysis. The prominent feature of life cycle costing is that it is based on the expected lifetime of a product which includes introduction as the strategic planning period, development, maturity, and decline. The aim of this costing approach is to generate the highest amount of profit for the corporation through the best marketing and production decisions in different levels of the product’s lifetime (Erden, 2004). In this context, life cycle cost management appears as a method which increases the efficiency during the decision making process. The method of life cycle costing management provides opportunities to a company for the execution of the long term planning which emphasizes the total life cycle costs. Through long term planning, this method encourages corporations to increase the expenditures during the early periods (design) of a product’s life cycle. Thus, it aims to choose the one with the most efficient costing among alternative methods to reach the least long term cost (Yükçü, 2007). Life cycle cost management uses the perspective of product life cycle. The two different perspectives of product life cycle are the cost life cycle and the sales life cycle (Blocher et., 2005). In a simple definition, product life cycle is the time period from the conceiving stage to the time when the product is withdrawn from the market. Product life cycle is generally covers the whole range of a product whereas it may refer to specific brands and models. Furthermore, a customer-based definition of product life cycles also becomes possible when the conceiving stage and buying stage are swapped. These producer-based and customer based approaches can be renewed by looking at the concepts of profit generation period and consumable period. Profit generation period refers to the period when a product/service generates profit for the company. A product’s profit generation period starts with its sale while the consumable period is the time frame when the product/service serves the customer’s needs. Profit generation period is in the producer’s sphere of interest whereas consumable period is in the customer’s sphere of interest. However, as consumable period can be used as a means of competition, it is highly important for the producer, too (Hansen and Mowen, 2006). Cost life cycle is the sum of consecutive activities in a company which start with research and development, and continue with design, production, marketing/distribution and consumer 2 Proceedings of 11th International Business and Social Science Research Conference 8 - 9 January, 2015, Crowne Plaza Hotel, Dubai, UAE. ISBN: 978-1-922069-70-2 services. This cycle is the product/service’s life cycle with respect to the costs. Cost life cycle is shown on Figure 1 (Blocher et., 2005). MARKETING R&D DESIGN & PRODUCTION CUSTOMER DISTRIBUTION Pre-production Costs SERVICES After-Production Costs Figure 1. Cost Life Cycle of a Product/Service Sales life cycle is composed of consecutive stages which start with the product/service’s introduction to the market and continue with the growth stage where the sales rise, the maturity stage, and the decline stage, and finish with the product/service’s withdrawal from the market. Sales life cycle is shown in Figure 2. Sales are low in the beginning of the life cycle, then reach the peak in maturity stage, and then descend again. (Blocher et.al, 2005). Almost all the costs and the environmental performance of the product are calculated during the design and development stage (Chan et.al., 2014). Sales Growth Intro. Maturity Decline Time Figure 2. Sales Life Cycle of the Product/Service The subjects of important strategic cost management arise in all the stages of cost or sales life cycles. The three instrumental methods in analyzing the cost life cycle are the target costing, constraints theory, and life cycle costing. Target costing is used to determine the profitable product designs during the early stages of cost life cycle. Constraints theory is a reformatory method used to lower the production costs and to increase the production speed during the middle stages of the cost life cycle. Life cycle costing is used during the whole period of the cost life cycle to lower the total costs. In addition to these three methods, there is also strategic pricing. Strategic pricing can be implemented if the corporation possesses many products in different life cycle stages. In such conditions, strategic pricing is used in planning product development activities and in determining the product’s price depending on the stage each product in sales life cycle is (Blocher et.al, 2005). These methods are generally used by the production companies where developing a new product, the speed of production, and efficiency are important matters. Since the product has 3 Proceedings of 11th International Business and Social Science Research Conference 8 - 9 January, 2015, Crowne Plaza Hotel, Dubai, UAE. ISBN: 978-1-922069-70-2 physical characteristics, for production companies the implementation of these methods is easier. However, it is also possible for service companies to use the aforesaid methods (Blocher et.al, 2005). In order to understand the life cycle cost management better, it is necessary to examine the key perspectives on product life cycle (Hansen and Mowen, 2006). 2. Life Cycle Perspectives Companies maintain marketing perspective and production perspective while consumers maintain customer perspective on product/service life cycle (Hansen and Mowen, 2006). Marketing perspective defines the product/service’s forms of sale during the different stages of its life cycle. Figure 3 shows a general course of the marketing perspective on product life cycle. The stages described in Figure 3 are introduction, growth, maturity, and the end. Introduction stage is the phase when the focus is on the introduction to the market. Preproduction and preparation activities refer to this stage. As seen on the chart, there are not any sales for a certain period (pre-production period), then the sales start and rise slowly as the product gets known. Growth stage is the time frame when sales rise in increasing rates. Maturity stage is the period when the sales rise in decreasing rates. In this stage, the skew of the sales curve becomes zero and it starts to fall in the decline stage (Hansen and Mowen, 2006). Sales Intro. Growth Maturity Decline Figure 3. The General Course of Product Life Cycle: The Marketing Perspective Production perspective defines the stages of product life cycle with respect to the changes in activities that take place during the life cycle. These activities are research and development activities, production activities, and logistic activities. While marketing perspective is interested in the profit from the sales, production perspective is interested in life cycle costs. Life cycle costs are the costs that are related to the product in the whole life cycle. These costs are research (related to the product) costs, development (planning, design, testing) costs, production (cycling activities) costs, and logistic support (advertisement, distribution, warranty, customer services, product services, etc.) costs. The curve of product life cycle costs is seen on Figure 4. Here, it is significant to notice that more than 90 per cent of the assumed costs related to the product arise in the development stage of the product life cycle. By assumed costs, costs that are included in the product’s constitution are meant (Hansen and Mowen, 2006). 4 Proceedings of 11th International Business and Social Science Research Conference 8 - 9 January, 2015, Crowne Plaza Hotel, Dubai, UAE.

Product Life Cycle: Production Perspective Customer perspective is interested in the stages of consumption life cycle. The stages of consumption life cycle are buying, using, sustaining, and disposing. Consumption life cycle perspective is to concentrate on the performance of a product based on a certain price. Price is the cost of obtaining the product and composed of buying cost, using cost, sustaining cost, and disposing cost. That is to say, overall customer satisfaction is affected by both buying cost and the costs after buying. Because of the reason that customer satisfaction is affected by afterbuying costs, producers pay close attention to managing the levels of these costs. The way producers use the connection between after-buying activities and producers’ activities on behalf of their interests is an important aspect of product life cycle management (Hansen and Mowen, 2006). All three life cycle perspectives provide different ideas for the product/service producers. Companies cannot ignore any of these three perspectives. An elaborative life cycle cost management program has to consider the diversity of the existing perspectives. Life cycle cost management is composed of activities that enable the designing, development, service, and disposal of a product/service and thereby maximize the profit of the life cycle. In order to maximize the life cycle profit, it is essential for producers to understand the relationships between the three life cycle perspectives and to benefit from these relationships. Thus, it could be possible for companies to multiply their incomes and to lower their costs (Hansen and Mowen, 2006). Marketing perspective is interested in the product’s sales course structure during its life cycle, and it is an income-centered perspective. Production perspective is interested in the activities that are needed for developing, producing, marketing, and providing services for the products. Production perspective stages support the sales targets the marketing stages. This support requires resources consumption. For that reason, production life cycle can also be defined as a spending-centered perspective. Consumption life cycle is connected with product performance and price (including after sales costs). Both the profit generation ability and resource consumption levels are related to product performance and price. Companies should focus on what customers buy and what they do not. Consumption life cycle can be defined as a consumer values-centered perspective. The relationship explained here can vary according to the structure of the sector of activities (Hansen and Mowen, 2006). 5 Proceedings of 11th International Business and Social Science Research Conference 8 - 9 January, 2015, Crowne Plaza Hotel, Dubai, UAE. ISBN: 978-1-922069-70-2 3. LCC for Generating Income and Reducing Costs Income generation approaches are connected to the marketing life cycle stages and customers. For example, pricing strategy changes in every stage. Higher prices can be set in the introduction stage as customers have low price sensitivities and they are mostly interested in the performance of the product. In the maturity stage, customers are highly sensitive both to the price and to the performance. Strategies such as adding new qualities to the product, increasing the durability, increasing the sustainability of product use, and provide customized products are appropriate for this stage. In the maturity stage, differentiating is particularly important. However, to ensure the increase of income, the customer must be eager to pay extra money for the increase in the product performance. What is more, this difference that will be paid by the customer has to be higher than the cost the producer has made to add a new quality to the product. In the decline stage, income can be increased by finding new areas of usage or new customers (Hansen and Mowen, 2006). Life cycle cost management, is an essential element with respect to cost management (Booth, 1994). Life cycle cost management’s main are of interest is not the control of costs but cost reducing strategies. By using different cost reducing strategies and with the studies done in the early stages of product life cycle, lower costs can be attained for later stages and consumption stages. When you consider the fact that 90 per cent of a product’s life cycle costs arise during the development stage, the importance of focusing on the management of costs during the development stage is obvious. The biggest opportunities of reducing the costs arise before the production starts. In order to lower the production, marketing, and after sale costs, administrators should make more investments on pre-production activities and allocate more resources for the activities in the early stages of the product’s life cycle (Hansen and Mowen, 2006). The stages of product design and process design provide many opportunities for reducing the costs. Some of them are: the design to lower production costs, the design to lower logistic support cost, customer retention, and the design to lower the after-sale costs including maintenance and disposal. For these approaches to be successful, company administrators have to comprehend the interaction between the activities, cost keys (contractors) and between activities well. Production, logistic, and after-buying activities are not unrelated to each other. Some designs can lower the after-sale costs and increase the production costs. While other designs can lower production, logistic, and after-buying costs at the same time (Hansen and Mowen, 2006). Traditional costing systems do not usually provide the necessary information generation for life cycle cost management systems. Traditional costing systems focus on using unit-based cost keys to define the costing behavior and are interested in production activities. In these systems, logistic and after-buying activities are ignored, while research and development costs with all other non-production costs are recognized as expenses as they appear. Traditional costing systems do not handle all the product related costs that come up during the life cycle. In fact, costing systems that are founded on generally accepted accounting principles do not support the necessities of life cycle costing management. However, activity-based costing system generates information on activities that include both pre-production and after-production activities and on cost keys (Hansen and Mowen, 2006). 6 Proceedings of 11th International Business and Social Science Research Conference 8 - 9 January, 2015, Crowne Plaza Hotel, Dubai, UAE. ISBN: 978-1-922069-70-2 4. Life Cycle Assesment and Environmental Accounting In 1990s, environmental accounting was mostly about environmental debates. Then a new approach was developed in accounting literature. Hence, environmental accounting focused on the accounting and management research problems (Bebbington and Larrinaga, 2014). While environmental accounting is discussed as a cumulative process, there is another matter of fact to consider: There are some restraining factors like profit making companies (Conrtafatto and Burns). Life cycle assesment from the viewpoint of environmental accounting is the evaluation of the environmental effects of product, process, and activities during the whole life cycle (Gilpin, 2000). Life cycle analysis and life cycle assesment are parts of a system which evaluates all environmental aspects of an activity from the acquisition of the raw material to the time all wastes have turned back to the nature (Gale and Stokoe, 2001). Life cycle assesment aims to find out all the interactions related to a product or a service (Gray and Bebbington, 2007). Cost life cycle is companies’ activities that start with research and development and continue with production, marketing, distribution, and customer services (Fava, 1991). This cycle is the life cycle of the product/service with respect to the arising costs. Important strategic cost management topics emerge in every stage of life cycle cost management. Life cycle cost management is used in the assessment of the total costs in the whole cost life cycle. This method is used by the companies where the product/service development, production/service speed, and efficiency are important. Since the product has physical characteristics, for production companies the implementation of these methods is easier. However, it is also possible for service companies to use the aforesaid methods (Blocher et.al, 2005). Life cycle assesment is a key approach related to companies’ interactions with the environment. This technique is closely interested in primarily changing the administration’s perspective and integrating the companies’ environmental effects to the management. It is necessary to remind that the calculation of a company’s all environmental effects is impossible. The aim of life cycle assesment is to calculate the interaction with the environment as much as possible (Gray and Bebbington, 2007). Life cycle assesment aims to meet the specific needs encountered during the product/service development and improvement stages. It is possible to lower or eliminate these costs by activities like monitoring the environmental costs in the sphere of life cycle assesment and reconstructing the processes. In this context, it is essential for corporations to develop a life cycle environmental costs system by evaluating the product/service’s environmental costs in every life cycle stage. Through integrating the environmental costs to life cycle cost system, it is possible to lower aforesaid costs in all the life cycle stages (Gray and Bebbington, 2007). 5. Conclusion Today, managers are expected to consider not only the production cost but also the product/service's costs that arise during the period from the concept stage until the end of the lifetime and even after they become waste. This process, named as the life cycle cost management, bears utmost importance with respect to environmental accounting activities. 7 Proceedings of 11th International Business and Social Science Research Conference 8 - 9 January, 2015, Crowne Plaza Hotel, Dubai, UAE. ISBN: 978-1-922069-70-2 With respect to environmental accounting the life cycle assesment, which means the evaluation of environmental effects of the processes and activities, aims to determine all of the interactions related to a product/service. It is possible to lower or eliminate the environmental costs by monitoring the environmental costs in the sphere of life cycle assesment and reconstructing the processes. Corporations should develop a life cycle cost environmental cost system on which they will follow their environmental costs in every stage of product/service production. Corporations should determine environmental policies and strategies in the transition to environmental accounting practices. Then, especially with the support, leadership, and participation of the senior management, they should develop the environmental accounting system for the purposes of determining and reporting the environmental costs during the service life cycle. Thus, it will be possible to lower, or even eliminate the damages on the environment caused by the companies.
