Prototype Partitioning Based on Requirement Flexibility

Abstract

Prototype partitioning is an often-overlooked step in the product development process that has great potential for improving project success. This paper discusses the importance of applying a systematic prototype partitioning strategy to a product development project. Quite often, prototypes are chosen based on historical reasons, with the premise that requirements are rigid and inflexible. Alternatively, a method is proposed here for prescribing a partitioning strategy that is tailored to the specific characteristics of a project and is based upon the three components of requirement flexibility: cost, schedule, and performance. By considering the realistic flexibility in these requirements, strategic prototyping decisions may be made to promote the success of a development project. Three product development applications illustrate the proposed method: the Black & Decker SnakeLight™, a senior-level design project at the United State Air Force Academy, and the product development of a new umbrella concept based on compliant components.© 2004 ASME
