Milestone B. Milestone B will normally be program initiation for Defense acquisition programs.
Program initiation depends on three things: a valid requirement (documented in
an ORD), maturity of technology, and funding. Prior to making the program
initiation decision, the milestone decision authority will confirm that
technology is mature enough for systems-level development to begin, an ORD has
been approved, and funds are in the budget and the out-year program for all
current and future efforts necessary to carry out the acquisition strategy. On
rare occasions, program initiation may be appropriate earlier than Milestone
B. If so, program initiation will take place upon entry into, or during,
Component Advanced Development. A successful Milestone B authorizes entry into
either the System Integration or the System Demonstration work efforts of the
System Development and Demonstration Phase. There will only be one Milestone B
per program, or evolutionary block.
