> I have seen estimation and tight project control taking up substantially more time than delivering actual features.

It sounds to me that what you saw was a conflation of estimates and plans. Which is a common error.

Clients sometimes want an estimate of how long a single feature or fix will take, even when it will take only 15 minutes. The communication overhead and time spent estimating easily outweigh the time to implement.

Nothing, just an explanation of what I meant by estimate.
