Introducing Design for Six Sigma
In This Chapter
Designing new processes
Doing the DMADV
Looking at the House of Quality
This chapter provides only an introduction to Design for Six Sigma (DfSS). It is simply an overview because the topic could easily form a standalone book. We look at the DMADV method – Define, Measure, Analyse, Design and Verify – as well as take a tour through the House of Quality (otherwise known as quality function deployment). But we stress that it’s only a tour and not a full structural survey!
It’s important to recognise there is a much wider range of concepts, tools and techniques used in DfSS projects, though the House of Quality is certainly an important part of the toolkit. This book does not look to cover benchmarking techniques (other than within the section on QFD), or TRIZ, the theory of inventive problem solving, for example, and there are many other tools, too, especially in the area of innovation.
Benchmarking is the process of seeking out the best performing products/services (performance benchmarking) and learning how these products/ services are produced (process benchmarking).
