Consumer preference measurement is a quantitative field of study for modeling, collecting and analyzing product decisions by consumers. Discovering how consumers choose products is an important area of marketing research and recognized as a successful partnership between academic theory and practice over the past forty years. Despite preference measurement’s success in consumer products, little guidance is available for its application to software product management. This paper assesses the feasibility of applying advanced preference measurement techniques to software products and suggests a framework for conducting such studies. A summary of the methods is provided to give guidance to software product managers seeking to apply preference measurement to common product decisions. The paper concludes by recommending a technique called ‘maximum difference scaling’ to elicit customer feedback to help measure the importance of new features for software product improvement. / text

Product management as an organizational system has a long history of practice, which predates most modern academic management research. Its activities span the external environment of the firm, while simultaneously spanning across internal functional specialties of the organization. Thus product management obtains, codifies, simplifies and stores external information making it available to a responsive organization, which uses it to establish competitive advantage and ultimately superior performance. Building on the resource based view of the firm and boundary theory, these spanning activities, which are heterogeneously dispersed across firms, are considered organizational capabilities. Drawing upon the extant product management literature, this research uses product management as a proxy for boundary spanning capabilities of the firm. These capabilities are then empirically measured against two well established firm capabilities; market orientation and firm-level innovativeness. This research addresses a gap in the literature by establishing product management as a set of firm-level capabilities, distinct from the well established constructs of market orientation and innovativeness. Results indicate that external product management capability, defined as channel bonding activities, fully mediates the market orientation – firm performance relationship, while firm level innovativeness continues to have a small mediating effect on performance. Internal product management capabilities, defined as market and technical integration are shown to negatively moderate the external product management capability - firm performance relationship. Theoretical implications include establishing a link between boundary theory and the resource based view of the firm. Practical implications include the strong relationship between external spanning capabilities and firm performance and the dampening effect of cross-functional integration on firm performance. This empirical link between product management boundary spanning practices and how firms ultimately perform could assist practitioners in allocating resources and managing the relationship between the marketing and technological factions of the organization. Most importantly this research establishes the hereto untested link between product management capability and firm performance.

In South Africa, Store brands are sold throughout retailers in the country and categories are widespread - from beverages (milk, coffee, water, etc); including most confectionary categories; most household and toiletry categories; and from premium brands, to the more cost effective. Compared to the U.S and Europe, the South African market for store brands is not well developed; however, there are still mega opportunities in the own brand category, as the market is far from being saturated. Even though South African retailers are utilizing own brands as a means of differentiation, some studies are also indicating the lack of well tuned major store brand strategies and own brands were not perceived as of value by consumers as well. Therefore, this study is undertaken to establish a greater insight into consumer perceptions toward The No Name Brand food items by investigating the influence of selected economic, psychosocial and demographic variables. Without a solid understanding of the consumer, the available growth opportunities in the store brand category are likely to be missed.For retailers to take advantage of the opportunities in the store brand category a greater understanding of consumer behaviour is required. For that purpose, relevant theories and concepts of consumer behaviour are included in the literature review for the study. / Thesis (MBA)- University of KwaZulu-Natal, 2004.

This study was an exploration of the product life cycle theory as a strategic decision-making tool in an auto-catalyst manufacturing plant. During the literature review stage of this study, many gaps in the product life cycle theory were identified. The product life cycle theory has come under criticism from numerous academic authors. It was also found that there was a definite lack of empirical studies carried out on South African companies and products. The main focus of this study was to investigate use and practical applicability of the product life in strategic decision making in a South African organisation, which is a subsidiary of a multinational corporation. A major limitation to this study was that the decision makers at Johnson Matthey South Africa showed a lack of understanding of strategy, and their role in strategic decision making. From the data collected, using a questionnaire survey methodology, the major findings were that the product life cycle theory has application potential as a strategic decision making tool in future, The decision makers at Johnson Matthey have a good knowledge of their products and where they were on the product life cycle. Further empirical research, into the applicability of the product life cycle theory is needed, on South African organisations. / Thesis (MBA)-University of KwaZulu-Natal, Westville, 2006.

Environmental costs of products are closely related to their environmental impacts incurred at all life cycle stages of a product. Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) methods are often used to estimate these environmental costs and impacts. However, LCA analysis is known to be a costly and time-consuming method, whereas LCC analysis often neglects the social cost which is currently paid by society as a whole. Therefore, this research proposes a new methodology to assess the environmental impact and social cost for the entire life cycle of a product, which can be used as a simple and transparent tool for the early conceptual design stage. The methodology delivers the Environmental Impact Drivers and the associated Social Cost Drivers for all product life cycle stages via spreadsheets, and it provides the Life Cycle Impact Assessment (LCIA) method in the SimaPro software as a user interface. Furthermore, the drivers provide the values for four different geographical regions and damage categories. The conceptual model is based on the impact pathway approach which integrates the Simplified LCA (SLCA) model and the social cost databases. The SLCA model is derived from an extension of previous research whereas the social costs are based on the most suitable Economic Valuation (EV) studies such as the EPS2000d, EXMOD, Ecosense and Asian EV studies. The data collection for the SLCA database was accomplished by using the LCA analysis of the Eco Indicator 99 H/A method and the Hierarchical clustering technique. The data for the social cost database was collected using the Benefit Transfer Method which obtains the EV studies mainly from the Environmental Valuation Reference Inventory (EVRI) data source. Several case studies utilising existing products, including a product redesign case study were used to prove the concept and demonstrate the efficiency of this proposed methodology.
