each planned stage of the design process are verified to implement the input requirements of the stage. 3. The specified process and products, including design outputs, are designed to be inspected at staged checkpoints. 4. The installed system functions as designed. Validation and integration tests, acceptance tests, and on-site pre-operational and start-up functional tests demonstrate that the identified critical hardware and software characteristics are verified. As discussed above, the Staff's determination of the qualification of digital I&C systems and components is based in part on confirmation that the software for the systems is developed using a disciplined engineering process. Typically, this process is described in a set of software life cycle process development planning documents, which define the process requirements and the commitments the applicant/licensee makes regarding software life cycle activities. Figure 7.0-A-5 identifies the software life cycle planning topics that should be considered for review. These commitments must be consistent with the commitments made for the design criteria and guidance discussed in Section C.3.1 above. Figure 7.0-A-6 outlines the procedures for reviewing software life cycle process planning. BTP HICB-14 describes the detailed regulatory bases and Rev. 4 — June 1997 SRP 7.0-A-11 material to be reviewed for evaluating software development life cycle process planning. Section B.3.1 of that BTP describes the acceptance criteria for this review. In addition to confirming the acceptability of the applicant/licensee's plans, this review activity should also identify the higher-risk activities of the software life cycle process for subsequent audit by the NRC staff. Almost every computer system will involve some use of PDS. PDS may be used directly in plant computers or in processes used to develop in-plant software. The applicant/licensee's process for qualification of PDS should be reviewed as part of the evaluation
