nt among the various plans reviewed. The licensee/applicant or vendor is expected to develop and implement a high quality process to ensure that the resultant software is of high quality. A V&V effort that is sufficiently disciplined and rigorous is essential to demonstration of a high quality software development process. For this reason, the staff confidence that the V&V effort will identify and solve the problems which could detract from a high quality design effort will require the careful review of the SVVP, as well as the various V&V reports. One of the most critical items in the SVVP is the independence of the V&V organization. The V&V team should be independent in management, schedule and finance (per RG 1.168). The reviewer should check that the V&V team is independent. V&V personnel should not be subject to scheduling constraints or to pressure from the software designers or project managers for reports or review effort, and the V&V team should report to a level of management which is not exerting direct pressure for a favorable V&V report. The staff reviewer should determine if the V&V effort is sufficiently independent to adequately perform the tasks without bowing to schedule and financial pressure. BTP 7.14-38 Draft Revision 6 - August 2015 A second important assessment the staff reviewer should make is on the number and quality of the V&V personnel. There is no specific requirement for the number of V&V personnel, but as an industry rule of thumb, it takes as much effort for a good V&V process as is required for the original design effort. This would indicate that if the V&V team is to keep up with the design team, there should be rough parity between the two groups in the number and skills of the personnel assigned. If the design group significantly outnumbers the V&V group, either the V&V effort will fall behind, or the V&V effort will not perform all the items required. Since there is no numeric requirement, this would be an indication to the staff
