  1. Define the problem, characterizing the general purpose of your decision.
  2. Identify the criteria, specifying the goals or objectives that you want to be able to accomplish.
  3. Weight the criteria, deciding the relative importance of the goals.
  4. Generate alternatives, identifying possible courses of action that might accomplish your various goals.
  5. Rate each alternative on each criterion, assessing the extent to which each action would accomplish each goal.
