information: The specific design commitments to be verified by the ITAAC, The inspections, tests, and/or analyses to be performed, and The corresponding acceptance criteria which demonstrates that the design commitment has been met. An example of one page of an ITAAC is provided in Figure 1 in this SRP section. The format of Tier 1/ITAAC is discussed further in Appendix A to this SRP section. As a part of the submission for a design certification under Subpart B or a combined license under Subpart C of Part 52, the applicant must submit a proposed life cycle and all of the plans which are required in the first phase of that life cycle. The BTP on Software Process, BTP ICSB-14, and the BTP on Level of Detail, BTP ICSB-16, describe the HICB branch position on reviewing these planning documents. Since the planning commitments for the software development process are reviewed as part of the application, the software ITAAC needs to cover only those phases titled Requirements through Installation. See Figure 2 in this SRP section. DRAFT Rev. 0 - April 1996 14.3.5-8 The software ITAAC should contain the commitments for each phase of the defined software development life cycle extracted from the planning documents, a method for verifying that each design commitment is met through inspection, test, or analysis, and an acceptance criterion for meeting the commitment. A set of acceptable commitments for each phase of the software life cycle is outlined in the BTP on Software Reviews, BTP ICSB-14, which also contains an acceptable method of verification and acceptable acceptance criteria for each of the commitments. The commitments in the ITAAC should reflect in detail the elements, activities, and documentation required of the various phases of the life cycle as shown in Figure 1 and as detailed in the BTP on Software Reviews, BTP ICSB-14. Inspection should be the method for verifying the commitment and the acceptance criteria for each commitment should closely parallel the
