Introduction
  • The Concept
  • The Challenge
  • Types of Development
  • Spiral Development Characteristics
  • OT&E Objectives
  • A Fitting
  • Navy Readiness Example
  • Summary
the concept
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
the challenge
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.
development processes
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
spiral development sd
Spiral Development (SD)
  • Characteristics
    • Risk-managed process
    • Stakeholder Involvement
    • Cyclic Approach
    • Incrementally grow definition & Implementation
    • Milestone Anchored
operational test evaluation
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

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
