4.4.5-1 Level 2 Tasks

Tasks Applicable Mission Phases Description SFWC Artifacts References
4.4.5-1-1 Ensure government involvement with design implementation and verification processes that consider all disciplines involved, and all interface organizations Phase A | Phase B | Phase C | Phase D1 | Ensure an assessment of required government talent (including government personnel, FFRDC, contractors) is conducted, consistent with program execution. A government plan should be in place with defined resourcing and accountabilities for each phase of the program. NA NA Mission Assurance Guide, TOR-2007(8546)-6018, Rev B, Program Assurance Chapter
4.4.5-1-2 Ensure impact of any critical issue associated with the subsystem is addressed with a timely execution plan Phase B | Phase C | Phase D1 | Ensure tracking and resolution activities are documented for any critical issues, as defined by the program. Ensure issues have closeout mitigation plans with schedules and resources that show acceptable closing for successful program execution within cost and schedule constraints. NA NA Space Vehicle Systems Engineering Handbook (TOR-2006(8506)-4494)
4.4.5-1-3 Ensure that the program executability methodology incorporates independent analysis and/or reviews to validate design, build and final product Phase B | Phase C | Phase D1 | Ensure that independent reviews be considered for manufacturing issues, parts issues, and issues involving Functional Configuration Audits, Physical Configuration Audits. NA NA Space Vehicle Systems Engineering Handbook, TOR-2006(8506)-4494
4.4.5-1-4 Ensure schedule for design, build and test is provided and is reasonable Phase A | Phase B | Phase C | Phase D1 | Ensure contractor has identified appropriate resources, risks and mitigation plans that make schedule feasible within budget constraints. NA NA Space Vehicle Systems Engineering Handbook, TOR-2006(8506)-4494
4.4.5-1-5 Ensure problem identification, failure review and corrective action processes are adequate Phase A | Phase B | Phase C | Phase D1 | Phase D2 | Phase D3 | Ensure that the PMPCB (Parts, Materials, Processes Control Board) and FRB (Failure Review Board) processes are in place and implemented. Ensure anomaly resolution is addressed and resolved through FRB, PMPCB, and other activities. Ensure all anomaly identification and resolution packages and sell-off packages are documented and filed. Ensure that failure and corrective action processes include interface to the problem alerting databases. NA NA Space Vehicle Systems Engineering Handbook, TOR-2006(8506)-4494,
4.4.5-1-6 Ensure lessons learned for applicability to subsystem, incorporation into design, manufacture/build, test and operations are reviewed Phase A | Phase B | Phase C | Phase D1 | Phase D2 | Phase D3 | Ensure lessons learned databases are reviewed and applied, as appropriate. Ensure interface exists to problem alerting databases, including surveillance of system for relevant alerts.
