Uhm, I think you're reading my post a bit uncharitably. I don't think I insulted you, for instance. I never said that estimates were meaningless, but they are tools for planning with high intrinsic uncertainty, and translating that uncertainty to evaluations gives unfairness. People are very sensitive to (perceived) unfairness and the idea that they will be treated so will give rise to resentment, not to mention incentives to game the system and overestimate. Hence endless bickering about points. If agile failed for any reason it was misunderstanding human psychology. Personally I don't think human performance in creative professions is well suited to quantified analysis, especially when team efforts are involved. So I don't really have an answer there.
