  2. Introduction • The Concept • The Challenge • Types of Development • Spiral Development Characteristics • OT&E Objectives • A Fitting • Navy Readiness Example • Summary

  3. The Concept • Evolutionary Acquisition(EA) “strategies” rely on a Spiral Development (SD) “process” for an earlier delivery to the warfighter • A Trade-off…. • May be less than full capability (…and less than fully tested), but… • Affordable, risk-reduced, agile, and earlier delivery of a product • Best Means of getting advanced technologies to the user

  4. The Challenge • Fitting Spiral Development into More Effective OT&E • DOD programs are increasingly going to spiral development to: • Get early buy-in from users on enhanced capabilities. • Spiral development presents a different challenge to: • Software Quality Assurance (SQA) • Operational Testing and Evaluation.

  5. Development Processes • Traditional - One extended process • Full system capability, but after a long time • Evolutionary - Multiple sequential extended processes • Full system capability per evolution – new technology as it comes • Incremental - Multiple sequential processes • Full system capability achieved by increments • Spiral - Multiple maturing cycles • Gradually maturing capability – early use of new technology

  6. Spiral Development (SD) • Characteristics • Risk-managed process • Stakeholder Involvement • Cyclic Approach • Incrementally grow definition & Implementation • Milestone Anchored

  7. Operational Test & Evaluation • Objectives - Characteristics • Operational Effectiveness • Operational Suitability • Reliability • Mean Time Between Operational Mission Failures (MTBOMF) • Maintainability • Mean Corrective Maintenance Time for Operational Mission Failures (MCMTOMF) • Availability • Operational Availability (Ao) = UPTIME / UPTIME+DOWNTIME • Survivability

  8. Spiral development Develop Design Spiral 1 Spiral n… Test Define Refine Conceptualize Feedback

  9. Spiral Development - OT&E Fit • Conceptualize / Feedback Phases • Planning is critical – Feedback is vital • Define /Refine Phases • Requirements traceability – Risk Management • Design Phases • Development Phases • Test (Development Test / Operational Test - DT/OT) • Simulation is one solution
