The key problem is always the same. The business wants to move as fast as possible, and developers are extremely concentrated in either the overly defensive "let us discuss ad nauseam" camp or the willing/passive "let's develop something and deliver it" camp. I don't agree with either, but frankly, I've had far more trouble convincing the former of their problem (analysis paralysis and wasting time) than the latter of theirs, and the former group is extremely convinced they have the high ground over the latter.

And I've dealt with 'seniors' willingly sitting in meetings not achieving anything and pushing silly refactors more than half a dozen times only to run into performance issues, bugs and terrible deployments. User complaints don't lie, the grass ain't greener on the other side.
