The Art of Action summary

Carl von Clausewitz joined the Prussian Army at age twelve in 1780, serving in combat just one year later. Over two decades of military service – including devastating defeats by Napoleon and eventual triumph – he accumulated hard-won insights about the nature of warfare. His magnum opus, Vom Kriege (which translates to On War), spanning over 1,000 pages across 125 chapters, introduced a concept that would prove prophetic for understanding organizational challenges centuries later: friction. 

Friction emerges whenever individuals with independent wills attempt collective action in fast-changing, unpredictable environments. It’s what makes executing strategy so maddeningly difficult for armies – and organizations. This isn’t a military phenomenon; it’s a human one. Friction arises from our fundamental finitude: we simply can’t know everything we need to know.

In 1806, Napoleon’s forces delivered a catastrophic double blow to Prussia at Jena and Auerstedt, shattering what had been considered a formidable military machine. The humiliation sparked a radical transformation. Under Helmuth von Moltke the Elder’s leadership, Prussia developed Auftragstaktik – a revolutionary system that directly confronted the three gaps plaguing military execution.

Von Moltke addressed the knowledge gap by prescribing acceptance rather than denial: acknowledge uncertainty, limit plans to essentials, and work with available information rather than fantasizing about perfect insight. For the alignment gap, he reversed traditional hierarchies: each organizational level defined how to achieve objectives, with senior commanders providing only necessary context – nothing more. For the effects gap, he institutionalized initiative within boundaries: junior officers weren’t just permitted but required to deviate from orders when circumstances demanded, provided their actions aligned with higher-level intent.

Many organizations come together behind a strong vision or purpose. But businesses operate in competitive arenas where something else is essential too: strategy. This is where many leaders stumble – they confuse strategy with exhaustive planning, falling headlong into the knowledge gap’s trap by attempting to predict an inherently unpredictable future.

Real strategy isn’t a detailed map; it’s a blueprint for decision-making that answers one fundamental question: How will we compete? In constantly shifting business environments, strategy functions as a compass. It provides either a heading, a destination, or both – but never pretends to chart every rock and rapid along the way.

The alignment gap poses a deceptively simple question: How do you get everyone on the same page? The answer isn’t about motivation or culture – it’s about information architecture.

Prussia’s catastrophic defeats at Jena and Auerstedt gave them new understanding: survival demands flexibility, which in turn requires at least some autonomy at every organizational level. But autonomy without coordination leads to chaos. The solution is making sure each level possesses precisely the right information.

Helmuth von Moltke understood something many leaders miss: organizational success doesn’t hinge solely on brilliant commanders making perfect decisions. It depends on the organization’s fundamental makeup – specifically, having the right people in leadership roles. These individuals need to balance two things: owning their decisions and adapting actions to fit their organization’s overall intent.

So where do you find such people? Start by knowing who to avoid. Some people perpetually delegate upward, refusing to take charge. Others swing to the opposite extreme – authoritarian micromanagers who crush team creativity. These outliers should raise immediate red flags.

We’ve now looked at how directed opportunism—rooted in Prussian Auftragstaktik and modern mission command—can bridge the gaps between plans, actions, and outcomes. But here’s the truth: every business is different. This approach needs to be adapted, not copied blindly.

So how do you go about adapting it? Start by distinguishing three domains: strategy, execution, and tactics.
