What did you learn? Isn't that the essential question of continuous improvement? Actual changes and improvements made, and their demonstratedvalue, are certainly important. And those changes are more tangible than changes in understanding. But what is more important? What will have more far reaching consequences? Probably what is learned.
Need it even be mentioned that learning without application is of little value? The value of learning must come from its application. So saying that learning is more important than application does not imply that learning without application is sufficient.
