ses provide an objective assessment of software products and processes throughout the software life-cycle. This assessment demonstrates whether the system requirements and software requirements (i.e., those allotted to software through software specifications) are correct, complete, accurate, consistent, and testable. At the concepts stage of the software and hardware life-cycle, the system’s functional requirements should be communicated between the plant systems engineers, the control room operators, the maintenance staff, and the software and hardware designers and vendors. This interaction should continue throughout the entire life-cycle of the computer system. These V&V processes are used to determine whether the development products of an activity conform to the requirements of that activity, and whether the system performs according to its intended use and user needs. This determination of suitability includes the assessment, analysis, evaluation, review, inspection, and testing of products and processes. In general, a thorough V&V effort will take as much effort as the design effort, and require an equivalent level of expertise. Reviewers should be careful to assess the quality and quantity of the licensee or vendor V&V team to ensure an adequate V&V effort is available. IEEE Std 7-4.3.2 adopts the IEEE Std 1012, “IEEE Standard for System and Software Verification and Validation,” terminology of process, activity and task, in which software V&V processes are subdivided into activities, which are further subdivided into tasks. The term V&V effort is used to reference this framework of V&V processes, activities, and tasks. The V&V processes should address the computer hardware and software, integration of the digital system components, and the interaction of the resulting computer system with the nuclear power plant. The V&V activities and tasks should include system testing of the final integrated hardware, software, firmware, and interfaces. The
