As defined and established by DoDI 5000.02, there are four decision points in the Defense Acquisition System (DAS) of phases, milestones and decision points. The decision points are:
Materiel Development Decision (MDD): MDD review is the formal entry point into the acquisition process and is mandatory for all programs. A successful MDD may approve entry into the acquisition system at any point consistent with phase-specific entrance criteria and statutory requirements but will normally be followed by a Materiel Solution Analysis (MSA) phase.
Capability Development Document – Validation (CDD-V): During the TMRR Phase, the requirements validation authority will validate the CDD (or equivalent requirements document) for the program. This action will precede the Development RFP Release Decision Point and provides a basis for preliminary design activities and the PDR that will occur prior to Milestone B unless waived by the MDA.
Development Request for Proposal (RFP) Release: Considered the critical decision point in an acquisition program. Milestone Decision Authority (MDA) review of the results of the Technology Maturation and Risk Reduction (TMRR) Phase prototyping effort and key related planning documents for the Engineering and Manufacturing Development (EMD) phase. Following a successful Development Request for Proposal (RFP) Release decision, the MDA authorizes release of the final RFP and source selection for the EMD contract. (The EMD contract cannot be awarded until after a successful Milestone B.)
Full-Rate Production Decision Review (FRPDR): Milestone Decision Authority (MDA) review to assess the results of Initial Operational Test and Evaluation (IOT&E) and initial manufacturing and deployment to determine whether to approve proceeding to Full-Rate Production or Full Deployment. Continuing into Full-Rate Production or Full Deployment requires demonstrated control of the manufacturing process, acceptable performance and reliability, and the establishment of adequate sustainment and support.
