This module is an attempt to address the difficulties that result from the concurrent, iterative, decomposition that must be accomplished when we apply SE to complex programs. As a general construct, this course differentiates between how to apply the SE methodology, which includes Requirements Decomposition, Functional Analysis and Allocation, Design Synthesis and Systems Architecting, at each phase of the LCAP.
One very beneficial step an SE can take to help plan out a technical acquisition effort is to define its systems acquisition process. We do this by dividing the project into phases separated by milestone events. The life cycle process, in DAU terminology, consists of time periods called phases, separated by decision points called milestones. These milestones provide the PM executive management the framework with which to review acquisition programs, monitor and administer progress, identify problems, and make corrections. The decision authorities will approve entrance into the appropriate phase or effort of the acquisition process by signing an acquisition decision memorandum upon completion of a successful milestone event. The life cycle process takes the program through determination of mission needs; research; development; production; deployment; support; upgrade; and finally, decommissioning and disposal.
