SYSTEMS ENGINEERING PROCESS. The systems engineering process is based on an iterative, top down, hierarchical decomposition of system requirements, supported by trade studies that record the basis for significant decisions and the options considered. The iterative, top-down, hierarchical decomposition methodology includes the parallel activities of Functional Analysis, Allocation, and Synthesis. The iterative process begins with system-level decomposition and then proceeds through the major subsystem level, the functional subsystem level, to the hardware/software configuration item (CI) or assembly/program level. As each level is developed, the activities of functional analysis, allocation, and synthesis will be completed before proceeding to the next lower level.
During the allocation process, systems engineering allocates performance and design requirements to each system function and sub-function. 1.
