Systems Engineering Processes

Systems Engineering defines a large body of knowledge pertaining to the various life-cycle phases of complex engineering projects. Clearly engaging with these different aspects, of the project process, can greatly increase the manageability reduce risks.

INCOSE publishes a complete guide to its members:

  • Systems Engineering Handbook: A guide for system life cycle processes and activities, 4th edition.

However, for any stakeholders engaged in an SE managed project, it is useful to see a tangible summary of the distinct processes (and the acronyms) that may be used and followed during the project. This will provide context during the engagement. It is common for the systems engineering team, to tailor the oversight, by selecting a subset of these processes, and then adjusting the level of detail and rigour according to the needs of the project.

To read this table note that:

  • outputs flow along the horizontals: an entry on the diagonal produces outputs that flow via the “routing” cells in the same row.
  • inputs flow along the verticals: an entry on the diagonal consumes inputs that flow via the “routing” cells in the same column.
