have been followed during the software project. The review and assessment of the quality of the plans provide a means of judging the competency of the development organization and management. It might be the case, particularly when the applicant or licensee is planning for future plants, that the software plans are created in stages as information becomes available. For example, budget and schedule information might not be available when the initial plans are created. This is acceptable, provided that the information is added to the plans prior to the time the information is needed to carry out the plans. In general, the staff review is intended to verify that safety is maintained through the development of high quality software. The staff does not review the various development plans to ensure that the process is cost-effective or on schedule. The staff should assess whether there is adequate budget and sufficient schedule to support a high quality design effort and provide the time required for a careful and thorough V&V effort. The staff review should focus on those aspects which can impact the safety and quality of the resulting software design. For future plants, it is possible that more than one vendor could be involved in the design and implementation of the plant digital I&C systems and the associated software. The planning documents and the associated implementation activities of the various vendors should be coordinated by the principal vendor responsible for the design of the plant project. Of particular importance are the interface requirements of the systems by the various vendors and the integration of the systems. It is also possible that since applicants or licensees generally contract the hardware, software or system development to a vendor, there may be two sets of planning documentation, that of the applicant or licensee and that of the vendor. Appendix B to 10 CFR Part 50 states that licensees may delegate to others, such as contractors, agents,
