Yesterday I saw the film Babel from director Alejando Gonzalez Iñárritu. There are various storylines (in Marocco, Japan, Mexico) and at some point you discover the link between the various storylines. The link between Marocco and Mexico gets confirmed when you see a picture of the children in their father's wallet. From the review of the film: "this movie is constructed as a puzzle, with different pieces transpiring during different times and in different places over a five-day span".
The feeling you get when you see the picture of the children, and suddenly, in retrospective, you understand some of the conversations that took place or some of the things that happened, is the same I have as an advisor when I get a certain clue. Suddenly a lot of things click. It is at that point in time that I feel certain and start to act (give feedback or whatever). As a facilitator or convenor for communities of practice (or other internal advisor role) I don't have that experience, though the puzzles remain. I guess that as an external advisor you have more distance and as a result, are able to see things more clearly. (this links to a previous post talking about the difference role of an internal and external advisor to a community of practice)
