In any crisis, try to find out as much information as you can. Even if you are not going to communicate that information, it's probably better to know as much as possible. That way, you avoid inadvertently saying the wrong thing or sending unintended messages. Consider the parameters of your crisis and try to conduct yourself accordingly when dealing with the media and others. Maintaining a sense of humor is important, but inappropriate humor can work against you.
Professional dignity is important, particularly in unpleasant times.
As the crisis progresses, jot notes for review later. The notes can help you remember things during the crisis and may be useful for later review. If you or others are on camera, always dress professionally. Overwork and no sleep can lead to misstatements, irritability and loss of friends. When the worst of the crisis is over, send notes of appreciation to those who have been of service, outside and inside the institution, and including your own staff.
