Becker's 5-levels of knowledge

1. Don't have a clue. Aren't even aware that the technique/method exists.

2. Know enough to be dangerous. While aware of the technique, we are just as likely to use it incorrectly as to use it correctly. Incorrect use can lead to wrong conclusions and/or inefficiency.

3. Know enough to be effective. We are likely to choose the proper technique/tool and use it correctly, resulting in an effective root cause analysis and solution to the problem.

4. Know enough to teach it. I used to think teaching should be easy - after all, we're only regurgitating what we already know. I quickly found out that learners will ask insightful questions that cause the instructor to think of the subject matter in new ways. The instructor often ends up being both teacher and learner. Teaching also requires the use of multiple ways of saying the same thing. What resonates with one learner may have little or no meaning to another learner until rephrased.

5. Know enough to make it up; that is, creating new methods/techniques from basic principles.
