This book is an improvement on the prior "System Validation and Verification" book that focuses more tightly on verification since the validation content was moved to the "System Requirements" book also published earlier by Elsevier Academic Press. The book tells how to develop verification requirements for each product requirement appearing in a specification so the combination of the "System Requirements Analysis" and this one covers the complete sweep of requirements work with clear traceability. All verification work is partitioned into three classes: (1) system test and evaluation responding to the content of the system specification, (2) item qualification responding to the content of the item performance specifications, and (3) item acceptance responding to the content of the item detail specifications. The secret to a well managed verification process is clear linkage between product requirements and verification requirements with a clear collection of verification requirements relative to a finite number of verification tasks of five types: (1) test, (2) analysis, (3) demonstration, (4) examination, and (5) special (may include simulation). Each task is assigned to a principal engineer who must prepare a plan and procedure for accomplishing the work and accomplish or support the work when the schedule prescribes. Matrices are offered that support sound management of the process on a program.
