Teams bounce back faster when the captain names what went wrong out loud, then moves on.

An unnamed failure stays in the room. People keep privately turning it over, each with their own version of who was at fault, and the whole thing occupies space that should be going into the next attempt. Saying plainly what went wrong, then moving on, takes it out of the realm of rumor and puts it in the past.

After the next thing that goes badly, say the one or two concrete reasons out loud and leave blame out of it. Then change the subject to what comes next. The speed of that second part is what makes the first part safe.
