Section D of this appendix. More detailed information on the regulatory bases, acceptance criteria, and review processes for specific issues are described in Section 7.1, related branch technical positions (BTPs), and regulatory guides. Definitions An activity group is a collection of software life cycle activities, all of which are related to a specific life-cycle topic. Eight activity groups are recognized in this appendix: planning, requirements, design, implementation, integration, validation, installation, and operations and maintenance. Critical characteristics are those properties or attributes that are essential for performance of an equipment's safety function (IEEE Std 934, "Requirements for Replacement Parts for Class 1E Equipment in Nuclear Power Generating Stations"). A similar definition is provided in EPRI NP-5652, "Guideline for the Rev. 4 — June 1997 SRP 7.0-A-2 Utilization of Commercial Grade Items in Nuclear Safety Related Applications," in relation to commercial dedication. Design output includes documents, such as drawings and specifications, that define technical requirements of structures, systems, and components (ASME Std NQA-1, "Quality Assurance Requirements for Nuclear Facility Applications"). For software, design outputs are the products of the development process that describe the end product that will be installed in the plant. The design outputs of a software development process include software requirements specifications, software design specifications, hardware and software architecture, code listings, system build documents, installation configuration tables, operations manuals, maintenance manuals, and training manuals. The design process comprises technical and management processes that commence with identification of design input and lead to and include the issuance of design output documents (ASME Std NQA-1). A design requirement is a requirement that specifies or constrains the design of a system or system component (IEEE
