Out of the Crisis by W. Edwards Deming, page 19
I am reminded of a quote I heard from Dr. Deming (though it may well precede him): “Don’t just do something, stand there.” First think, then act. His quote also relates to the tendency we have to tamper – institute “solutions” without understanding what is going on (often due to a lack of understanding variation). Many managers have learned their job is to act, even if they don’t have the knowledge needed to make a rational decision: they don’t just stand there, they do something. Learning to say, I don’t know, and then spend time learning instead of acting is a valuable skill to develop.
