Software Design for Six Sigma: A Roadmap for Excellence

Chapter 11. SOFTWARE DESIGN FOR SIX SIGMA (DFSS) PROJECT ROAD MAP

INTRODUCTION

This chapter is written primarily to present the software Design for Six Sigma (DFSS) project road map to support the software Black Belt and his or her team and the functional champion in the project execution mode of deployment. The design project is the core of the DFSS deployment and has to be executed consistently using a road map that lays out the DFSS principles, tools, and methods within an adopted gated design process (Chapter 8). From a high-level perspective, this road map provides the immediate details required for a smooth and successful DFSS deployment experience.

The chart presented in Figure 11.1 depicts the road map proposed. The road map objective is to develop Six Sigma software-solution entities with an unprecedented level of fulfillment of customer wants, needs, and delights throughout its life cycle (Section 7.4).

The software DFSS road map has four phases Identify, Conceptualize, Optimize, and Verify and Validate, denoted ICOV in seven developmental stages. Stages are separated by milestones called the tollgates (TGs). Coupled with design principles and tools, the objective of this chapter is to mold all that in a comprehensive implementable sequence in a manner that enables deployment companies to achieve systematically desired benefits from executing projects. In Figure 11.1, a design stage constitutes a collection of design activities and can be bounded by entrance and exit tollgates. ...
