what I've seen a lot over the years is that an engineer gets asked about timeline, thinks for about 10 seconds, blurts something out, then if it's off (too short) they bust their asses / cut corners trying to hit their own estimate. Since estimates are usually optimistic, I tend to see a lot of over time and/or corners cut.

there's certainly an element of personal pride in that dynamic I think. You're asked to give an estimate. You give it. You now feel like you've staked your professional rep to it.

the author shares his method for coming up with estimates, and it looks like an offline process that involves more than a gut check. I think for sufficiently large features we (eng managers, eng peers) should encourage engineers to _not_ give on the spot estimates given we know how difficult it is to estimate.
