Having set the Defence of Requirements Drift (or whatever I called it) to one side several months ago, I’ve been in a quandary. Although I feel I’ve got a fair bit of systems engineering (SE) experience under my belt, a lack of recent practice has got me thinking about the fundamentals once more.
The biggest fundamental has to be “Why Systems Engineering?”
This naturally breaks down into the eternal three reasons: Right thing to do, in the right way, for the right price
Probably the strongest argument is that SE is doing things in the right way. Whether it’s the right thing is going to be context dependent, and the right price is whatever the client can afford (and with the correct risk and so on).
