In dire time, you win by focusing your entire team around one focal point. Explain that survival comes from a certain objective, and focus everyone on it.

Wart-time management isn't the same as your day-to-day management. Set the objective, explain what everyone is to do to achieve it, and crucially important, outline exactly how success and failure is going to be measured.

You may not win, but you can put your team in charge of their own destiny.
