outsiders see the big picture
One of the interesting "side effects" of this project was the discovery of the great connectedness of the yellow nodes -- the outside contractors -- in this project. They were better integrated in the knowledge flows of this project than any other group -- they reached more people, over shorter paths. Of course, the bad news is that these contractors will all leave at the end of the project, and the company will no longer have access to their knowledge. The company did not want to lose key knowledge from, and about, the project. They set up regular knowledge-sharing sessions where key network nodes would share their wisdom, experience and learning about the project. This allowed the knowledge to flow from the well-connected contractors back into the regular organization.
