You're not providing an alternative, though. You have a team of smart people. They come up with 3 interesting proposals. You have the bandwidth to execute on only one of them. At some point, a decision has to be made (by you, by vote, whatever). Two guys on your team are going to hate that decision. Are you going to be OK with those two not contributing to the end goal (i.e. the "commit" part)? Are you going to be OK with them bringing it up in each team meeting and 1:1 over the next year? Are you going to be OK with them not voicing their opinions (i.e. the "disagree" part)? What's your alternative? As pointed out in a submission a few days ago, the worst experiences tend to be teams that always blindly do what the boss tells them, and at the other end of the spectrum, teams that question every little detail - all the time. Disagree and commit addresses the latter. I've been in that team - it sucks. Never again.
