This is the first of two issues of IDA’s Research Notes focused on acquisition in the Department of Defense. These two issues will cover topics related to program inception, program execution, and managing a portfolio of
acquisition programs. In this issue, we present articles related to program inception—specifically, starting viable programs. Establishing feasible programs at Milestone B is truly a critical step. Programs that enter development with flawed assumptions or concepts must address the consequent problems during execution—sometimes resulting in Nunn-McCurdy breaches. This issue contains articles on three challenges that programs must address at inception: selecting the system’s capability and its specific attributes, accurately estimating cost and schedule, and choosing an appropriate acquisition strategy.
