Systems Engineering Process

FavoriteLoadingAdd to favorites


The Systems Engineering Process is a comprehensive, iterative and recursive problem solving process, applied sequentially top-down by integrated teams. It transforms needs and requirements into a set of system product and process descriptions, generate information for decision makers, and provides input for the next level of development. The process is applied sequentially, one level at a time, adding additional detail and definition with each level of development. [1]

The four (4) steps that comprise the SE Process are:

Systems Engineering Process - Overview

Requirements Analysis Functional Analysis/Allocation Design Synthesis

  • There is no one standard definition or systems engineering process. It’s a collection of ways and means across many disciplines. Best practices, guidebooks and lessons learned are a great source of systems engineering knowledge.
  • Each program is different so there is no one process that perfectly fits. It’s the job of the systems engineer to modify the process to meets their programs needs the most
