Because this entire Mantra is horrible advice. All 3 need to be in the spec, and all 3 need to be coded for.

"Make it fast" sometimes does not need to be coded for if the applications is fast enough after the "Make it right" step.

Doesn't matter, every app has some speed requirement.. if it is trivial, then there isn't much to do for it.

It's not something you can just do later, because thats not how software works. Fast code needs designed to be fast. Not "fixed" at the end.
