Systems Engineering in Technology Maturation and Risk Reduction


Alternate Definition
(Note: This article is updated to reflect the interim DoDI 5000.02 Change 2 dated February 2, 2017 and the subsequent Defense Acquisition Guidebook (DAG) revision.
The Technology Maturation and Risk Reduction phase focuses on maturing critical, enabling technologies-thereby reducing program risk-before commitment to the Engineering Manufacturing and Development (EMD) phase at Milestone B. This phase marks the separation between technology and product development:
  • Matures technologies and undertakes risk reduction,
  • Examines design and requirements trades necessary to ensure an affordable product and executable develpment and productions,
  • Determines the appropriate set of technologies to be integrated into a full system,
  • Supports Test and Evaluation (T&E) planning,
  • Conducts competitive prototyping of system elements,
  • Matures and validates capability requirements,
  • Develops the allocated baseline of the end-item system configuration approved at the Preliminary Design Review (PDR),
  • Develop Reliability, Availability, and Maintainability (RAM) strategy,
  • Validates the draft Capabilities Development Document (CDD),
  • Support development of the Request for Proposal (RFP) and timing of the release decision.
