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

The Concept n n Evolutionary Acquisition (EA) “strategies” rely on a Spiral Development (SD) “process” for an earlier delivery to the warfighter A Trade-off…. n n n 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

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

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

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

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