Publisher Summary This chapter provides an overview of process verification. The verification of process plans and procedures is accomplished by monitoring the preplanned program and functional metrics and using the results as the basis for the actions taken to improve program performance. Process verification occurs subsequent to the design and implementation phase. However, the results of the process-verification work may be more useful to the next program rather than the current one. Metrics collected early in the program may yield improvement suggestions that can be applied prior to the end of the program, but metrics data collected later in the program may not be useful for that program. Program process verification is the connecting link for continuous process-improvement activities that progressively improve the company's capability and performance over time. Program process verification provides a conduit for lessons learned from each program experience to the company's future of diminished faults. The chapter discusses program and functional metrics along with the use of a cost/schedule control system in process verification and concludes with a discussion of the concepts related to progressive planning improvements.
