I'd expand on that model a little...

A good engineer starts with the simplest model to prove the idea, then
adds factors that in  their judgment says will be a problem.  Normally
only a couple things at MOST at a time, to reduce the degrees of freedom
when it breaks and needs correcting.

The best use the 'extra' effects as a feature in the design when the
effect is understood well enough to be predictable and manufacturable
enough to be repeatable. =20

I don't remember if it's been requoted here or not, but one attributed
to Einstein was "The supreme goal of all theory is to make the
irreducible basic elements as simple and as few as possible without
having to surrender the adequate representation of a single datum of
experience." =20

I prefer the pithier if inaccurate translation , "Everything should be
made as simple as possible, but no simpler."  It's a simpler model...
