Purpose

The purpose of this handbook is to incorporate the applicable regulations and manuals into a handbook that covers the major phases of the ISD process and addresses them to the various phases of defense system acquisition. The ISD process has application in all acquisition phases, but the major effort occurs between the demonstration and validation phase, and the production and deployment phase (Figure 1). The acquisition cycle can last ten years or more, requiring frequent coordination and evaluation, revisiting prior effort and redirecting as required.
