ion 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. Safety means that the installation tables introduce no new hazards into the safety system. Security means that the installation tables introduce no new security threats into the installed system, and that the installation tables are protected from unauthorized change. B.3.3.6.2 Process Characteristics of ICTs The configuration tables should exhibit each of the specified software development process characteristics: completeness, consistency, correctness, traceability, and verifiability. Completeness means that the software configuration tables include all information necessary for the correct operation of the system. BTP 7.14-63 Revision 5 - March 2007 Consistency means that the installation configuration tables are consistent with the software specifications, as described in the SRS, software design description, software code, and software build documents. Correctness means that the software configuration tables contain all plant-specific data. Traceability means that it is possible to trace each installed program element backward to the integrated software elements that created that installed program element. Verifiability means that it is possible to analyze, review, or test each installed software system on initial software installation, all subsequent installations, and periodically during operation. B.3.3.6.3 Review Guidance for ICTs In the event that the software has options for use, variable setpoints or other data, or may operate in various methods, the software needs to be configured for the particular plant requirements. Any software item which is changeable should have the intended configuration recorded in the ICT, and the reviewer should sample these configuration items to verify that they are correct. The reviewer should verify that the V&V team has
