That I can possibly agree with, when it is ourselves we are challenging with the deadlines and when we are talking about a launch or not situation. For teams I think that mentality more often than not leads to poor results and quality. Rushing without taking the time needed to do something "right" (I'll leave it as an exercise for the reader to determine what's "right" for them) just isn't sustainable long term. Take Balsamiq which takes the exact opposite stance here: http://blogs.balsamiq.com/team/2011/09/07/pace/ http://blogs.balsamiq.com/team/2011/09/07/pace/ I think that is a far more realistic and sustainable guideline to work from.
