The document provides an overview of NASA's policy for independent program reviews:
1. NASA policy mandates independent reviews at key decision points to validate programs' readiness and identify risks. This includes NPD 1000.0 requiring checks and balances like independent reviews.
2. The Standing Review Board process in NPR 7120.5 standardizes independent reviews across NASA. Reviews assess technical and programmatic status at life cycle milestones.
3. The SRB Handbook provides guidance for Standing Review Boards to apply review criteria consistently across programs in accordance with NASA's technical and program management requirements. It outlines the roles, processes, and expected work products for the reviews.
