Retrospective estimates could work better, but I imagine it lends itself to a lot of credibility problems. If you're popular and well-liked, you'll get retrospective estimates that exceed how much time you actually took. If you're unpopular, your manager/teammates can screw you over by giving estimates that are lower than how much time you took. Not to mention the fact that things always seem so much simpler in hindsight, especially when someone does a really good job with design. Butt-in-seats management, despite being much maligned, is much more consistent with the NoEstimates movement. Instead of trying to estimate how much time something is supposed to take, just mandate that they spend X hours working everyday.
