3.5  V&V in In-Service Management

The primary goal of ISM is to support execution of the FAA mission of providing air traffic control and other services.  Systems, products, services, and facilities are operated, maintained, secured, and sustained in real time to provide the level of service required by users and customers.  In addition, fielded products and services receive periodic monitoring and evaluation, and performance data is provided to ongoing MA and IA activities as the basis for revalidating the need to sustain deployed assets or taking other action to improve service delivery.  This includes configuration management, preventive and corrective maintenance, training, infrastructure support and logistics support, emergency sustainment actions, and the removal/disposal of obsolete assets.  Also included is the sustainment of flight inspection, aircraft certification, and regulatory requirements.

The primary focus of V&V during ISM is to ensure that any modifications to the product meet new/modified requirements and that any new/modified requirements or operational concepts are valid.  It is particularly important to ensure that the product continues to fulfill its intended purpose throughout its lifecycle.  Additionally, during ISM, all major work products associated with the product modifications are subject to V&V.

ISM has many significant decision points.  However, the major decisions evolve around whether to continue sustaining or to dispose of the product.  Consequently, the decision points for ISM along with the corresponding minimum required work products, product components, and products that must be verified and/or validated, the criteria for the V&V activities (i.e. what each must be V&V’d against) in addition to the concurrence of the appropriate stakeholders, and the stakeholders responsible for V&V are identified in Table 6.
