Verification, Validation, and Testing of Engineered Systems

A.2 SYSTEST KEY PRODUCTS

The SysTest consortium developed two key products: (1) a VVT Methodology Guidelines (VVTMG), a document containing SysTest’s collected body of knowledge related to system VVT and (2) a VVT Process Model (VVTPM), a quantitative model as well as a software embodiment to appraise system VVT strategies in terms of project time, cost, risk and product quality.

1. VVT Methodology Guidelines. The purpose of the VVTMG document (SysTest, 2005) was to provide a generic and customizable VVT methodology. The VVTMG describes a collection of 41 VVT activities and 31 methods applicable to the various system lifecycles. In addition, the VVTMG provides a collection of tailoring rules for different environments (industrial sectors, lifecycles and project types). The SysTest consortium agreed to make the VVTMG a public domain document. Therefore it was distributed widely around the globe. The VVTMG was a key source for writing Chapters 2–5 of this book and the author wishes to express deep appreciation and gratitude to the entire SysTest team.

2. VVT Process Models. Two quantitative VVTPM packages were developed during SysTest. These models embody an iterative planning technique which offers an effective method for smooth integration of the VVT planning with other system engineering activities. This technique supports maximal fulfillment of project goals and objectives. The specific objectives of this effort were to (1) predict the VVT cost, duration and resulting product ...
