efully planned and controlled software development effort should incorporate these specific activities into an orderly process within the software life cycle, including pre-software and post- software development processes. This regulatory guide addresses the subject of designing software life- cycle processes appropriate for the development of safety system software. The following criteria in Appendix B to 10 CFR Part 50 contain requirements closely related to software life-cycle activities. These listed Criterions are only part of and not the entire requirement: • Criterion I, “Organization,” requires, in part, the establishment and execution of a quality assurance program. • Criterion II, “Quality Assurance Program,” requires, in part, that activities affecting quality are accomplished under suitably controlled conditions that take into account the need for special controls and processes to attain the required quality. • Criterion III, “Design Control,” requires, in part, that measures be established for the identification and control of design interfaces and for coordination among participating design organizations. • Criterion VI, “Document Control,” requires, in part, that all documents that prescribe activities affecting quality, such as instructions, procedures, and drawings, be subject to controls that ensure that authorized personnel review documents, including changes, for adequacy and approve them for release. • Criterion VII, “Control of Purchased Material, Equipment, and Services,” requires, in part, that measures are established to ensure that purchased material, equipment, and services, whether purchased directly or through contractors and subcontractors, conforms to the procurement documents. • Criterion XV, “Nonconforming Materials, Parts, or Components,” requires, in part, that measures are established to control materials, parts, or components that do not conform to requirements in order to prevent their
