aused by software, and to identify hazards whose resolution will be under the control of software. The plan should require that appropriate safety requirements be included in the software requirements specification. It should define the safety-related activities to be carried out for each set of life cycle activities, from requirements through operation and maintenance. The plan should identify all Rev. 4 — June 1997 Appendix 7-A BTP HICB-14-22 documentation required for the proper and safe operation of the software. Procedures should require monitoring the software safety function performance during operation of the system. The plan should require that hazards identified by plant safety analysis, system safety analysis and security vulnerability assessment be traceable to the software safety analysis whenever these hazards can affect software operability or whenever software has a role in controlling the hazard. Resource Characteristics The resource characteristics that the software safety plan should exhibit include methods/tools and standards. Methods/tools requires a description of the methods and tools used to carry out the safety activities. The plan should specify a process for selecting tools. It should describe a method for preventing the inadvertent introduction of hazards by the use of project tools. Standards requires a list of the international, national, industry and company standards and guidelines to be followed by the safety organization. j. Software Verification and Validation Plan The software verification and validation (V&V) plan should exhibit the management, implementation and resource characteristics listed below. Reg. Guide 1.168, which endorses ANSI/IEEE Std 1012, "Software Verification and Validation Plans," shows an acceptable organization and content for this plan.
