No, I mean in the development of software. My experience is that
almost always the deadlines are to tight and there is only regard for
delivering as soon as possible, to keep the run-over as short as
possible. Taking some time to make it easier for someone else (but
also yourself) to maintain the program later on, would be in my
opinion a very wise investment.

Something I also often heard (but to be honest less often, so there is
improvement): we never have time to do it correctly, but we always
have time to mend the bugs.
I would think that delivering software with less bugs (no bugs is
impossible) would be more time efficient.

Typing code fast is no problem, writing code fast could. To quote

    sharpening my axe.

Three quarters is maybe a bit much, but I agree with the gist.
