Success is a teacher only when we explicitly engage it. Teams don't automatically learn from their successes. It needs to be fostered with questions designed to extract learning from successes. Not having this learning becomes a glass ceiling on the performance potentials of the team. Analysis of failure in no way compensates for a lack of learning from success. Success yields a whole different set of lessons compared to failure. This needs to be a habit, done periodically and at the end of projects. The more the process has a narrative quality, the more powerful it is.
