How do you make decisions?

Via this post by Estelle Metayer I came across the 4 minute video embedded below with Henry Mintzberg. In the video, Mr. Mintzberg introduces 3 ways of making decisions: # 1: Thinking first First you diagnose, then you design, then you decide, then you act / do. # 2: Seeing first Once you have seen it, you decide. # 3: Doing first You act in order to think, as much as you think in order to act. In other words, if you are faced with a decision and don’t exactly know what to do, you try something. If what you do works, you do more of it. If it doesn’t work, you try something else.
