The Art of Controlling One's Trade Secrets.

From an Amazon ad,

Developed by a former San Francisco 49er, this complete "training camp" playbook includes every feature of football's most successful offense ever! Over 400 pages of actual X & O diagrams, detail of techniques, terminology, and offensive philosophy. Assembled in a 3-ring binder for your convenience, this playbook is essentially the same as the ones used by NFL coaches for teams such as the San Francisco 49er's, Green Bay Packers, and Denver Broncos. Exactly like the real thing!

It does not matter if someone secured your playbook. Every technology and tactical manual has a cycle. Smart organizations always improve their technology and update their play books.

A good grand and operational strategist always thinks ahead in terms of the following: their strategic platform; their standard of performance and their contingencies.

He or she might explain to the outsiders their philosophy. Rarely do they ever reveal their operational and tactical management details. The outsiders seldom know the reasoning behind their actions.

Compass Rule: The man who knows why will always prevail over the men who knows how.
