Decisions in Product Platform Development Projects

Introducing "product platforms" in companies to achieve competitive advantages, like decreased costs and increased product variety, is a widely recognized strategy in research and industry. Nevertheless, there are certain challenges involved in developing product platforms. In order to address this complexity, we focus on the decision-making perspective of platform development in this paper. Based on a systematic literature review, we identify the decisions in product platform development projects (PPDP) and categorize them. We identified 21 decisions that are made within PPDP, which represent a greater scope of decisions than presented in the literature sources reviewed. The plausibility of these platform project decisions is illustrated with a case study of a perennial platform development project within the automotive supply industry. While most of the literature sources only mention very few decisions, the case study shows the complexity and high number of decisions required for an actual PPDP. In addition, it also recognizes all of the prior reviews of the decisions identified. Unlike in the literature, the decisions in the case study were made over a certain period of time. Therefore, we propose that the dynamics of the decision-making process in PPDP have to be taken into account. The set of PPDP decisions identified will help project managers to structure future PPDPs better and support researchers in building related product platform models.

Linking 10 Years of Modular Design Research: Alternative Methods and Tool Chain Sequences to Support Product Platform Design

Modular product platforms have been shown to provide substantial cost and time savings while still allowing companies to offer a variety of products. As a result, a multitude of product platform methods have been developed over the last decade within the design research community. However, comparison and integration of suitable methods is difficult since the methods have, for the most part, been developed in isolation from one another. In reviewing the literature in modularity and product platforms, we create a generic set of twelve platform design activities. We then examine a set of product platform development processes used at several different companies, and from this form a generic sequence of the activities. We then associate the various developed methods to the sequence, thereby enabling the chaining together of the various modular and platform design methods developed by the community.
