Design requirements formulation : a framework and analysis

Abstract

This thesis focuses on the early stages of the product development process, during which the set of design requirements is formulated. Given the proven importance of a comprehensive set of design requirements in the market acceptance of a product, we explore the formulation of design requirements and the potential sources of uncertainty that can arise during this early phase of the development process. This thesis seeks to answer two main questions: What events and conditions are likely to increase the project's uncertainty during the formulation of the design requirements? And, in what way can the effects of these events and conditions be avoided or mitigated? Using the information gathered through an extensive literature review, a descriptive framework was compiled. The information used was validated following two different paths: first, the evolution of the set of design requirements of several teams in a product design and development class was analyzed and, second, veterans of industry were interviewed about their experiences during the development process.
