Lessons Learned or Lessons Not Learned? At this moment, at several levels in various disciplines, there are discussions and debates going on about Lessons Learned. The concern is the question, at what point do Lessons become Lessons Learned? It is a question that has the attention of business leaders, PhDs, schools of management, blogsters, and students alike. Often, conspicuously absent from these dialogues, is the question of the validity of the lessons themselves- the quality of the initial data itself. Typically, a lesson is intended to communicate the source of the problem and the solutions available for application in similar situations. More realistically important is that the lesson be a valid one, and that learned means that something is going to be done, or has already been done to recognize and deal with its causal origins. It means that we have learned our lesson, understand why we needed to change . . . and have changed.
