The “told you so moment” is just out there waiting to appear. The potential for passive-aggressive org dynamics is all too real. Ultimately, this is just a yucky place to be. So if you’re on the “winning” side of such a dialog then you have to bring people along every day for a while. You can’t remind people who was right, or that it is your decision and so on. If you’re on the “losing” side you need to support the team. You can’t remind people when little things go wrong (which they will) that you were right. Once a choice is made, the next step is all about the greater good. Nothing is harder for technologists than this because as technologists we believe there is a “right” answer and folks that don’t agree are simply “wrong”. Context is everything and remember you have to ship–as a team.
