New Business Ideas Take Time by Edward DeBono

Good point. This is true for at least too reasons: short term thinking and the desire to have a measure of success. It is much easier to find a measurement of the benefit of eliminating some problem than the benefits of learning and taking more time to think. As Lloyd S. Nelson said many of “the most important figures that one needs for management are unknown or unknowable.”

Sounds very much like lean thinking to me.
