> But, unless management wants to get rid of estimates and deadlines, it is advocating an antagonistic belief system. I agree that 'at all cost' doesn't seem reasonable. Yet I think they should try very hard to avoid them. Estimates, meeting and deadlines might be required some time. You might had to announce a release date for some new features. That's a deadline you can't always avoid. But you can avoid arbitrary deadlines that are just there to 'motivate' engineers and get them to ship "something". That leads to worse quality and technical debt decreasing overall productivity on the long term.
