Content:
ent process characteristics: completeness, consistency, correctness, traceability, and verifiability. Completeness requires that the software configuration tables include all information necessary for the correct operation of the system. Consistency requires that the installation configuration tables be consistent with the software specifications, as described in the SRS, software design description, software code, and software build documents. Correctness requires that the software configuration tables contain all plant-specific data. Traceability requires that it be possible to trace each installed program element backward to the integrated software elements that created that installed program element. Verifiability requires that it be possible to analyze, review, or test each installed software system on initial software installation, all subsequent installations, and periodically during operation. g. Installation Activities & Operations Manuals One or more software operations manuals should be produced. They may be incorporated into a system operations manual. Because operations manuals do not impose requirements on the software itself, the functional characteristics described in other sections of this BTP are not directly relevant. However, the software development process characteristics listed below should be exhibited by software operations manuals. Completeness requires that all actions available to the system operator be fully described for all operating modes, including error recovery and backup. Operator actions should be specified in terms of inputs supplied by the operator or equipment, actions initiated by the operation, and responses to the operator. The purpose and operation of each function should be described, including interfaces with other functions. The operations manual should describe the operational environment within which the software will operate, including precautions and limitations that must be observed during operations to avoid
