d in Safety Systems of Nuclear Power Plants." • IEEE/EIA Std. 12207.0-1996, "Industry Implementation of International Standard ISO/IEC 12207: 1995 (ISO/IEC 12207) Standard for Information Technology Software Life Cycle Processes." BTP 7-21-4 Revision 5 - March 2007 IEEE/EIA Std. 12207.0-1996 is a software standard for organizing and managing software life cycle processes. This standard states in part: • Clause 5.3.4.1 - performance requirements shall be established and documented as part of software requirements analysis. • Clauses 5.3.5.6, 5.3.6.7, 5.3.7.5, 5.3.8.5, 5.3.9.3, 5.3.10.3 and 5.3.11.2 - software requirements, including performance requirements, shall be traced through architectural design, detailed design, coding, testing, software integration, software qualification testing, system integration, and system qualification testing. • Clauses 6.4.2 and 6.5.2 - requirements, including performance requirements, shall be verified and validated throughout the software life cycle. IEEE Std. 1012-1998 is a standard for software verification and validation (V&V). Detailed criteria for the V&V tasks are given in IEEE Std. 1012-1998, Table 1. This table states in part: • Clause 5.4.2, "Requirements V&V Activity," (2) "Software Requirements Evaluation" - performance requirements (including timing, sizing, speed, capacity, accuracy, precision, safety and security) shall be evaluated for correctness, completeness, consistency and testability. • Clause 5.4.2, "Requirements V&V Activity," (5) "System V&V Test Plan Generation and Validation" - system test plans shall include test designs, cases, procedures and results for, among other requirements, system performance requirements, performance at boundaries (such as data and interfaces), and under-stress conditions. • Clause 5.4.3, "Design V&V Activity," (2) "Software Design Evaluation" - design elements shall be evaluated to ensure that performance requirements are correctly and completely included. •
