(CCB) should exist with the authority to authorize all changes to baselines. Problem reports should be prepared to describe anomalous and inconsistent software and documentation. Problem reports that require corrective action should invoke the change control activity. Change control should preserve the integrity of configuration BTP 7.14-50 Revision 6 - August 2016 items and baselines by providing protection against their change. Any change to a configuration item should cause a change to its configuration identification. This can be done via a version number or attached change date. Changes to baselines and to configuration items under change control should be recorded approved and tracked. If the change is due to a problem report, traceability should exist between the problem report and the change. Software changes should be traced to their point of origin, and the software processes affected by the change should be repeated from the point of change to the point of discovery. Proposed changes should be reviewed by the CCB for their impact on system safety. Status accounting should take place for each set of life cycle activities prior to the completion of those activities. The status accounting should document configuration item identifications, baselines, problem report status, change history and release status. The configuration management organization should audit life cycle activities to confirm that configuration management procedures were carried out in the life cycle process implementation. B.3.2.4 Acceptance Criteria for Testing Activities RG 1.152, which endorses IEEE Std 7-4.3.2, “IEEE Standard Criteria for Digital Computers in Safety Systems of Nuclear Power Generating Stations,” with a few noted exceptions, identifies an acceptable methods for satisfying computer system qualification testing requirements (See: IEEE Std 7-4.3.2 Clause 5.4.1, “Computer System Testing”). RG 1.168, Section C.7.b, “Regression Analysis and Testing,” and C.7.d,
