“In making tactical dispositions, the highest pitch you can attain is to conceal them; conceal your dispositions, and you will be safe from the prying of the subtlest spies.”
The peak of planning is invisibility of the plan itself; conceal it and even the clever cannot undo you.
Chapter 6 grades concealment explicitly: in making tactical dispositions, the highest pitch you can attain is to conceal them. Not the perfect feint, not the brilliant stroke — the hiding of the arrangement itself. The promise attached is absolute: concealed dispositions leave even the subtlest spies prying at nothing. In an age of competitive intelligence, Sun Tzu names opacity as the summit of planning rather than an afterthought.
A company’s every visible move is deliberate chaff: job postings for skills it does not need, conference talks about products it will not build, office leases in cities it will not enter. Meanwhile the real build — one team, one city, unannounced — is contractually invisible inside a partner’s org. Analysts model the chaff confidently and completely. By the time the real move is legible, the position it created is two years old.
Concealment of dispositions is not institutional secretiveness toward your own side — troops cannot execute arrangements they cannot see, and Chapter 5 built the signals for exactly that. The opacity faces one direction: outward. And chaff costs money and credibility; the discipline is worth it only where reverse-engineering your position would actually change an opponent’s behavior. Hide the plan, publish the rest.
