My thoughts as an enterprise Java developer.

PurposeOfEstimation: "For me, estimation is valuable when it helps you make a significant decision." i.e. "allocation of resources" or "to help with coordination"
"So whenever you're thinking of asking for an estimate, you should always clarify what decision that estimate is informing. If you can't find one, or the decision isn't very significant, then that's a signal that an estimate is wasteful. When you do find a decision then knowing it focuses the estimate because the decision provides context. It should also clarify the desired precision and accuracy."
"I once remember a gnarly project manager say that plans and estmates were like a lettuce, good for a couple of days, rather wilty after a week, and unrecognizable after a couple of months."
