Trite and worthless. I've never yet seen a project that got perfect (or attempted to do so and ever shipped or delivered) and it is almost never a goal.

The tug of war is more often between putting unfinished things into production and some random deadline set by a person who knows nothing about the required amount of work to have a correct result. (Much less decent or maintainable.) Not negotiable or adjustable too.

Even the sc(r)um approach of cutting features has limitations. At some point the customer will just be unhappy.
