Why: The Weibayes technique uses your failure data and past experience to make Weibull analysis forecast about what you should expect into the future and in may cases, given a hypothesis of worst-case/best-case a failure forecast can be generated.

When: Use the technique when you lack specific details but you know something from your past experience-often the past experience reduces errors of Weibull analysis. Use Weibayes analysis to make sense out of emotional non-sense.

Where: Use the technique to say something and point noses in the right direction rather than playing the role of Chicken Little with the sky falling. Some data is better than no data in most cases and when you can keep your wits and everyone else is in panic mode, it quiets the problem to allow reason to prevail.
