tion reports should be described. The SInstP should require that anomalies discovered during installation be reported to the developer and resolved prior to placing the software into operation. Either the SInstP, or the SVVP, should require adequate testing to provide confidence that the installed system will perform its safety function. Plans for installation of software on installed systems in operating plants should recognize the need to declare all affected functions inoperable according to the plant’s technical specifications before proceeding with installation, and to conduct appropriate return-to-service testing before declaring the modified function operable. B.3.1.5.3 Resource Characteristics of the SInstP The resource characteristics that the SInstP should exhibit include methods/tools. Methods/tools involve a description of the methods, techniques and tools that will be used to accomplish the installation function. The SInstP should require that installation tools be qualified with a degree of rigor and level of detail appropriate to the safety significance of the software which is to be installed using the tools. B.3.1.5.4 Review Guidance for the SInstP The SInstP should be checked for the various management, implementation, and resource characteristics shown above, but there are no specific review guidelines. Since the software is being installed in hardware, the personnel performing this installation should be a mix of the software and hardware personnel. The critical part of the software installation is the system test (Note: per IEEE Std 1012, Final System testing is considered a V&V test, and is the responsibility of the V&V group). There should be written and approved procedures for software installation, and for combined hardware/software installation, and systems installation. In a sufficiently complex system, these procedures may contain some errors, and one of the things a reviewer should monitor is how these errors are identified, corrected
