  2. K.T. Problem Analysis • Useful for troubleshooting, where cause of problem is not known. • Basic premise is that there is something that distinguishes what the problem IS from what it IS NOT. • The distinction column is the most important

  3. IS IS NOT DISTINCTION WHAT: Rash Other illness External contact WHEN: New planes used Old planes used Different materials WHERE: Flights over water Flights over land Different crew procedures EXTENT: Face, hands, arms Other parts Something contacting face, hands and arms Only some attendants All attendants Crew duties K.T. PA Example

  4. K.T. Decision Analysis • Write a concise decision statement about what it is we want to decide • Use first four problem-solving steps to gather information • Specify objectives of the decision, and divide into musts and wants • Evaluate each alternative against the musts • Go vs. No Go • Give a weight (1-10) for each want • Pairwise comparison can help with relative weights • Score each alternative
