This diagram represents the life cycle the Navy Doctrine  knowledge base.

A Fleet Sailor with an idea, submits it to NWDC, NWDC evaluates it, gives it the tumbs up or down, NWDC promulgates new doctrine, the training community updates their products and teaches a new crop of operators.  Then the cycle repeats at every level of experience and operations.
