Max Leibman practically wrote my next article in his comments on "Step One in Crisis Management". The second step in crisis management is to form a quick plan to address the crisis. The key word is "quick" as opposed to "ideal." Grab anything that will address the problem quickly: better to grab a stack of napkins than get out the perfect towel for the job.
And Troy Worman chimed in with step zero of have a plan. I think that's not quite right for crisis management. In crisis management I think step zero is to be prepared with warnings and options. For example, to prepare for the crisis of a fire, we have the warning of a smoke alarm, and the options of sprinklers, fire extinguishers and a local fire department. In our spilled milk example, we have a roll of paper towels at hand.
Step three in crisis management is to appropriately clean up the mess caused by the imperfection of step two. Once the crisis is averted, you have time to go into regular project management mode. You have the time to address the problem in a more ideal way.
