Initiatives Were Put In Place to Address: Incomplete or unnecessary test requirements Immature test capability Inefficient test conduct Success found in: Application of systems engineering tools and methods Teaming across design and test functions early in the design cycle Test engineering participation in requirements and V&V development Questioning why past requirements are needed Questioning current methods of verification Focusing on problematic design features and complex integration areas Optimizing affordability to include risk mitigation (cost avoidance) as well as cost reduction Effective Verification & Validation Testing Summary - Commercial Airplane Product Development

A culture change is often necessary to qualify “Affordability” as cost optimization, to include investment in early verification and risk mitigation Using test experts to scrutinize design requirements and means of verification leads to a more robust and mature product Shifting verification “to the left” as much as practical helps ensure a mature and cost-optimized product Focusing on test readiness and efficiency throughout the development life cycle helps ensure verification success Complex systems yield emergent effects. Some of them increase risks, some of them increase opportunities. Effective Verification & Validation Testing Conclusions
