e system) backward to the code elements contained in the build. It should be possible to trace each element of the integrated build forward to the software field installation. Verifiability means that it is possible to analyze, review, or test each integrated software build for the product functional requirements. The system build documents should specify methods to detect incorrectly built software releases. The build documents should identify all errors and anomalies discovered during software build activities. B.3.3.5.3 Review Guidance for SBDs The SBD is needed to verify that the software actually delivered and installed on the safety system is the software which underwent the V&V process and was tested. Any future software maintenance will depend on the maintainers knowing which version of the software to modify. The reviewer should check to ensure that the software listed in the build documentation is identified by version, revision, and date. The reviewer should also verify that this is the version and revision which was tested. This information should all be available from the configuration management group. B.3.3.6 Installation Activities - Installation Configuration Tables (ICTs) Installation configuration tables should be produced. They should include all of the functional characteristics listed below to ensure that the software will be correctly configured in the operating safety system. The software development process characteristics listed below should be exhibited by the installation configuration tables themselves. B.3.3.6.1 Functional Characteristics of ICTs For each of the functional characteristics, the requirements imposed on the configuration tables for that characteristic should be satisfied. Functional characteristics addressed by the configuration tables should include functionality, safety, and security. Functionality means that the installation tables configure the installed system to have the functionality that is required for the plant.
