“Reduce the hostile chiefs by inflicting damage on them; make trouble for them, and keep them constantly engaged.”

Sustained pressure on the opponent's leaders denies them calm to plan; engagement is a form of control.
Chapter 8’s pressure doctrine: reduce the hostile chiefs by inflicting damage on them; make trouble for them, and keep them constantly engaged. The target is specified — the chiefs, not the ranks. And the mechanism is specified — not destruction but occupation. A leadership that spends its calendar firefighting cannot spend it maneuvering, and Sun Tzu counts that difference as a victory before any battle.
A smaller vendor cannot outspend the enterprise giant — so it out-busies it. Every quarter: a standards-body proposal requiring formal response, a public interoperability challenge the giant’s customers start asking about, a regulatory inquiry-in-a-letter. None individually fatal; all collectively consuming. The giant’s product leadership, interviewed a year later, describes a roadmap "that never quite happened" — twelve months of deliberation absorbed by a rival’s postage budget.
Keeping them busy is not workplace harassment of individuals — the pressure targets the organization’s planning capacity through legitimate competitive acts: standards, challenges, questions that deserve answers. And it must be affordable; a busy-making campaign that costs you more attention than it costs them is Chapter 2’s attrition war in miniature. The ledger, as always, decides.
