Defining an Action Plan

Try to identify all of the variables that could affect the problem. As you troubleshoot the problem, try to change only one of these variables at a time. Keep records of what you do and the effect of each action.

It's advantageous to develop your plan on paper. Decide what steps you want to take, and what you expect to do based on the results of each step. Then do the steps in order, and follow your plan.

If you see a result for which you have no plan:

• Go back to the isolation phase.
• Identify what happens in similar situations.
• Define another plan.
