Milestone Decision Authorities for Defense Business Sytems

The Milestone Decision Authority (MDA) (for Defense Business Systems):

  1. Approves critical acquisition decisions for ATP decision points or concurs in contractual commitments.
  2. Oversees business system delivery within cost, schedule and performance parameters.
  3. Establishes oversight controls for programs, including procedures to report cost, schedule and performance variances and to address reported variances. The acquisition chain of command supports the MDA by leading the program manager and program execution. Specific leadership roles vary by organization but often include the CAE and Program Executive Officer.

1. Transitions from lower to higher business system categories based on FYDP cost thresholds become effective no later than when the President’s Budget is submitted to Congress.
2. Business systems will not transition automatically from higher to lower business system category even if FYDP costs no longer exceed thresholds for the higher category.
3. Business systems that meet Major Automated Information System thresholds in Chapter 144A of Title 10, U.S.C., must meet the statutory requirements of Chapter 144A until its repeal takes effect.
