Completion estimates may be dishonest but that's how things are done almost everywhere, yes, even shops that use Agile, complete with burn-down charts, stand-ups and sprints. I've seen "Agile" teams that go through all the motions of a modern sw development team BUT STILL have to give the completion date of the whole project! Before the work starts!

FWIW, it's not as bad as it sounds, it just means that the PM's see red in their charts and end up bugging people with "urgency attacks". Slippage is common and that's OK.

The vast majority of the time, an estimate is just an estimate. Passing a deadline isn't fatal, nor is it failure (regardless of whatever it says in the Project Management Book of Knowledge).
