Verification, Validation, and Testing of Engineered Systems

3.1 STRUCTURE OF CHAPTER

This chapter describes a set of VVT activities that typically occur within the system post development phases (Production, Use/Maintenance, and Disposal). We provide detailed information for each VVT activity in a standard format designed to aid the reader in determining the activity’s applicability to a specific system lifecycle phase. As mentioned before, one should (1) tailor the VVT methodology by using the tailoring guidelines presented in the first, introductory chapter and (2) consider using the VVT process model for optimizing the VVT strategy. Subsequently, at the beginning of each system lifecycle phase, one should consider updating the VVT planning document. Typically, each VVT activity may be carried out within one of the following system post development lifecycles:

1. Production. This produces the completed system in appropriate quantities.

2. Use/Maintenance. This operates the system in its intended environment in order to accomplish intended functionality, maintains the system and corrects any defects.

3. Disposal. This properly disposes of the system and its elements upon completion of its life.

As mentioned in Chapter 2, each VVT activity is related to one of three aspects: (1) preparing the VVT products, (2) applying VVT to engineered products and (3) participating in or conducting technical reviews. Also, the reader should note that we continue to describe each VVT activity in terms of objectives, description and methods and ...
