"What are we really going to do with this? Why are we doing it? What purpose is it going to serve? How are we going to use this information?" This typically gets answered casually: "We are going to use the evaluation to improve the program" — without asking the more detailed questions: "What do we mean by improve the program? What aspects of the program are we trying to improve?" So a focus develops, driven by use.”

In my opinion this cascading series of questions is the need of the hour, especially when it comes to KM programs. Level at which you stop asking the question determines the level of utility of the program itself.
