Abstract This paper further develops the previously introduced concept of Design for Variety (DFV). Our study seeks a tool that enables product managers to estimate the cost of introducing variety into their product line. This will help them to maximize market coverage while maintaining required profit margins. Variety incurs many indirect costs that are not always well understood or are difficult to capture. These costs are often not considered by people making the decision about introducing variety. Our DFV model attempts to capture these indirect costs through the measurement of three indices: commonality, differentiation point, and set-up cost. These indices will allow the decision makers to estimate some of the generally unmeasurable costs of providing variety. We conclude this paper by discussing our validation plans for testing the model in industry.

AbstractVintage goods are a unique set of goods that accrue value over time. Unlike producers for many other vintage goods, Scottish distilleries often mature their stocks to different ages and sell a product line that varies significantly in quality. This article develops a theoretical model to examine this maturation strategy and identify market conditions under which a distillery would produce multiple ages of whisky. An empirical analysis of distilleries’ product lines confirms results from the model and highlights the determinants of variety and substitutability between brands.

AbstractThis study investigates the internal factors of excessive product proliferation. Since empirical literature on product over-proliferation focused on how to optimize existing product portfolio, the causes of excessive product proliferation have so far attracted little attention. This study employs a case study of Shiseido, a famous Japanese cosmetics company, with particular attention to product proliferation in the Shiseido chain store channel, because external factors are mostly absent from this case. My results indicate that intra- and inter-organizational inertia affects product line management. Due to Shiseido’s effort in the 1990s, the company could maintain the advantage it and its cosmetics store channel held with much the strategy as had been used until the mid-1970s. This strengthen intra-organizational inertia at Shiseido. Inter-organizational inertia with cosmetics stores makes Shiseido’s strategic change more difficult, which causes excess proliferation.
