Destroys every 'vision and values' slide deck you've ever seen.
Why this book
Rumelt defines bad strategy not as the absence of good strategy, but as a specific type of noise: fluff (words that sound strategic but mean nothing), goals dressed as strategy, wishful thinking dressed as plans. Once you see this pattern, you see it in every leadership off-site, every OKR deck, every 'strategic initiative'.
The kernel of good strategy is simple: a clear diagnosis of the challenge, a guiding policy that addresses it, and a set of coherent actions that follow from that policy. Three parts. All three required. Most organizations have the third and miss the first two.
The chapter on using strength against weakness — focusing resources on a pivot point — is the closest thing to a no-BS framework for execution under constraint.
Key principle
Strategy is not goals. It's a diagnosis of the challenge and a coherent response to it.
