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.
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.
