Feedback is the breakfast of champions.
Yes, the Kenn Blanchard, originator of Situational Leadership as it departed in to version 2. The quote matters; without feedback there will be no champions. Without someone — the old-fashioned sports coach or the modern leader — to provide honest comments and suggestions there will be no improvement. Feedback must be of the 3C kind — Concrete, Constructive and Caring. And it must be a fulfilling experience!
