" Wernher von Braun, who led the Marshall Space Flight Center’s development of the rocket that propelled the moon mission, balanced NASA’s rigid process with an informal, individualistic culture that encouraged constant dissent and cross-boundary communication.

Von Braun handwrote comments in the margins, and then circulated the entire compilation. Everyone saw what other divisions were up to, and how easily problems could be raised. Monday Notes were rigorous, but informal. "
