A subdivision of a phase of the Defense Acquisition Management System (DAMS) as established and defined by DoDI 5000.02. There are two major efforts for each of three phases, with six in total. The efforts of the Engineering and Manufacturing Development (EMD) phase are Integrated System Design (ISD) and System Capability and Manufacturing Process Demonstration (SC&MPD); the efforts of the Production and Deployment (P&D) phase are Low-Rate Initial Production (LRIP) and Full-Rate Production and Deployment (FRP&D); and the efforts of the Operations and Support (O&S) phase are sustainment and disposal. The efforts to be accomplished for any phase are defined in the program's acquisition strategy and program structure and depend on the program's particular situation or business case. The Materiel Solution Analysis (MSA) and Technology Development (TD) phases are not divided into efforts.
