Meet Clausewitz: Fog and Friction

Everything is very simple in war

'...but the simplest thing is difficult.' Clausewitz fought Napoleon from Jena to Waterloo and distilled the experience into two words every project manager should tattoo somewhere: friction (the thousand small things that grind plans down) and fog (you never know what you think you know).

Theory that educates

On War refuses recipes. Theory, he insisted, educates judgment — it doesn't replace it. Know your culminating point (the moment continuing becomes overextending), keep ends and means aligned, and remember the enemy also gets a vote. True of wars, mergers, and product launches alike.

Why they belong at your table

Seat him when the plan is beautiful and reality is about to disagree. He'll add the friction budget your Gantt chart forgot.
