Purpose

The Mission Definition Reveiew (MDR) examines the functional and performance requirements defined for the system and the preliminary program/project plan, and assures that the requirements and the selected architecture/design will satisfy the mission.

Timing

Near the completion of the mission definition stage.

Objectives

The objectives of the review are to:

  • Establish that the allocation of the functional system requirements is optimal for mission satisfaction with respect to requirements trades and evaluation criteria that were internally established at MCR
  • Validate that system requirements meet mission objectives
  • Identify technology risks and the plans to mitigate those risks
  • Present refined cost, schedule, and personnel resource estimates.

Criteria for Successful Completion

The following items compose a checklist to aid in determining the readiness of MDR product preparation:

  • Do the defined system requirements meet the mission objectives expressed at the start of the program/project?
  • Are the system-level requirements complete, consistent, and verifiable? Have preliminary allocations been made to lower levels?
  • Have the requirements trades converged on an optimal set of system requirements? Do the trades address program/project cost and schedule constraints as well as mission technical needs? Do the trades cover a broad spectrum of options? Have the trades identified for this set of activities been completed? Have the remaining trades been identified to select the final system design?
  • Are the upper levels of the system PBS completely defined?
  • Are the decisions made as a result of the trades consistent with the evaluation criteria established at the MCR?
  • Has an optimal final design converged to a few alternatives?
  • Have technology risks been identified and have mitigation plans been developed?

Results of Review

A successful MDR supports the decision to further develop the system architecture/design and any technology needed to accomplish the mission. The results reinforce the mission's merit and provide a basis for the system acquisition strategy.
