Every organization and leader drops the ball from time to time. Details slip, assignments are missed, and it’s usually the people downstream who suffer for it. When that happens, it’s too late to undo the past. What can be done is to acknowledge what went wrong and what you will do differently in the future. Failing to do this sends a message that leaders are either unaware or unconcerned.
People do not expect perfection from leaders. They do expect that when mistakes are made, the leaders at the top will own it.
