On almost all your points, I do agree with you. But for one: > are right a lot/disagree and commit don't seem to matter if the opposing argument is your manager wanting to do other stuff "Disagree and commit" means that when you don't agree with the decision being made, you make that clear, you state why, but then you commit to the decision that was made and work with your team to achieve the goals. It means you don't whine throughout the project that it wasn't done the right way, and you don't bullshit with "I told you so" later if you turn out to be correct. If your manager makes the call that it's going to be done in way X, you disagree with him politely, then you commit to doing it way X. What I find far more interesting about the leadership principles is that they recently dropped one: "Vocally self-critical". Oh, that's really just part of 'Earn Trust', apparently, but I'll bet in two more years that phrase isn't even part of the Earn Trust description anymore.
