The reflex inside most organizations is to wait for clarity. To convene the right people. To draft the right statement. By the time that work is done, the narrative has been written without you, and you are responding to a version of events you did not shape.
The discipline is not speed for its own sake. It is the practiced ability to make the smallest number of decisions that preserve the largest number of options. Acknowledge what is true. Decline to speculate on what is not. Designate one voice. Show, do not promise, that you are taking it seriously.
Crisis communications is not a script. It is a posture — one that has to be built before it is needed.
