Two conflicting views of how to go about it:
General Leslie Groves:
"Compartmentalization of knowledge, to me, was the very heart of security. My rule was simple and not capable of misinterpretation - each man should know everything he needed to know to do his job and nothing else." (General Leslie Groves, from Now It Can Be Told (New York, Harper & Row, 1962)
This unfortunate approach has been described as almost the classic recipe for preventing originality.
Enrico Fermi:
"Scientific thinking and invention fluorish best where people are allowed to communicate as much as possible unhampered." - Enrico Fermi, quoted in Frontiers 2002 (Argonne National Laboratory, 2001)
