Chapter 7

Obtaining Quality Data and Optimizing VVT Strategy

The purpose of this chapter is to discuss system quality cost information available in the literature and to show a practical and straightforward way to obtain such quantitative data. This process is illustrated utilizing a real-life pilot project conducted by the Israel Aerospace Industries (IAI)/Lahav division during the SysTest project.

Next, the chapter discusses the VVT-Tool, which was developed at IAI to support the modeling of quality cost and optimization of the VVT strategy discussed in this book. Finally, this chapter provides a collection of optimization techniques which may be used during the development of engineered systems, facilitating a reduction of 10–15% in engineering manpower or schedule.
