Thanks for sharing, and most of these are really good. For this one, you have the nucleus of the idea right here, though a team really needs to know itself for such a blanket statement to be true. It can be incredibly powerful for a team to hear, “We didn’t get it done this time, and that’s all right… Here why we didn’t, and what we’ll do next time.” Boats rise and sink with the tide, not just boats’ captains. Nothing wrong with an entire team collectively celebrating successes or sharing in failures. Some food for your thinking!
