The transition from system development into operations, and the subsequent system maintenance and sustainment activities, present organizations with many challenges. V&V addresses these challenges and reduces the potential that anomalies will arise.
During the transition phase the V&V team reviews the transition and activation products, ensuring they meet system needs. Developers are responsible for developing the transition and activation products needed for deploying the system. The products include the preparation of the system for each user site, manuals for each user site, source files, system descriptions for the maintenance site, as-built system data for the maintenance site, and transition plans for transitioning to the maintenance site.
During sustainment, both the cost and risk of defect correction and system upgrades is high. Drivers for such modifications include hardware and/or operating system changes, user errors occurring during operations, other software enhancements, and problems with or replacement of components developed outside of the development plan.
During this phase, V&V performs an assessment of the developer products, which supports the transition of the modifications into the operational phase. Proposed modifications are analyzed to ensure that the changes to be made are correct and do not interfere with other parts of the system or jeopardize the mission. The V&V staff independently assesses such potential modifications and are tasked with identifying risks of introducing new errors into the system and/or other options to achieve the needed changes. These V&V assessments avoid costly rework.
