There's a lot to like in what you write. Back to the book I referenced above ... disagreeing here has several facets. First you have to be aware you can disagree. You have to be aware you have choice and use it. Disagreement is not a firing offense. Bosses are not entitled. Second, how it's done is important: if I disagree through a defensive behavior (again see book) that will go bad ... If at the end a decision is made and feel like I had no choice or my ego won't allow it ... well that's another potential concern. Again disagreement isn't often itself the real problem. The real problems are: what if I know I can disagree but I don't? Lack of courage my side or unsafe environment made by management? If management tells me they've made their decision contradicting my input which applies: I feel listened to and feel like my input was taken seriously? That's good. Or perhaps I'm insecure and can't deal with loosing control. If I don't have self awareness here I might blame, critisize management or play victim. That can be bad. Maybe I just can't admit my assessment was incomplete or wrong. Also likely to hit into problems. And in any of this I refuse to change, I can sink the team in the limit.
