Good Strategy Bad Strategy: The Difference and Why It Matters by Richard P. Rumelt — Summary & Review

Let’s get one thing straight: most “strategies” out there aren’t strategies at all. They’re wish lists, fluffy slogans, or just plain avoidance of the real problems. Richard Rumelt, a seasoned strategist and UCLA professor, slams this confusion head-on in Good Strategy Bad Strategy. His core argument? Real strategy is about facing the hard truth of what’s actually going on, then crafting a clear, focused plan that tackles the key challenge with coordinated actions. It’s not about grand visions or buzzwords, but about smart choices and gritty execution.

Rumelt breaks down good strategy into three down-to-earth parts. First up is diagnosis—this is where you cut through the noise and figure out what’s really going wrong or what the biggest obstacle is. Think of it as the X-ray that reveals the real issue beneath the surface. Without this step, you’re flying blind or chasing shiny distractions.

Next comes the guiding policy. This is your overarching approach to the problem, your ‘game plan’ if you will. It’s not a laundry list of goals; it’s a clear direction that sets boundaries and priorities. It’s where focus happens, and where you decide what you won’t do, just as much as what you will.

Finally, and most importantly, you get to coherent actions. This is the execution part—specific, coordinated steps that make the guiding policy real. Without this, strategy is just talk. Rumelt stresses that these actions need to align tightly; scattered or half-hearted efforts won’t cut it.

On the flip side, bad strategy is everywhere. It’s vague, filled with fluff, and often pretends that simply having ambitious goals equals strategy. Rumelt calls out the common traps: mistaking goals for strategy, ignoring the real problems, and lacking any meaningful plan to tackle them. It’s a recipe for frustration and failure.

The book doesn’t just theorize. Rumelt peppers his points with sharp examples. He contrasts companies that thrived by focusing on a clear challenge and executing well, with those that collapsed under the weight of complexity and denial. For instance, he points to a tech company that trimmed down its product line, cut distractions, and zeroed in on what mattered, turning a sinking ship into a powerhouse. Meanwhile, another firm’s reckless risk-taking without a coherent plan spelled disaster.

Rumelt’s style is refreshingly blunt and practical. He doesn’t sugarcoat the difficulty of crafting good strategy, nor does he fall for the usual hype about quick fixes or one-size-fits-all formulas. Instead, he encourages leaders to embrace hard thinking, focus, and adaptability.

That said, the book isn’t perfect. Some readers might find the advice a bit high-level, craving more step-by-step guidance on turning diagnosis into action. Also, while the examples are vivid, they sometimes lean heavily on business and military cases, which might feel distant if you’re in a different field.

Published in the early 2010s, right after the global financial crisis, Good Strategy Bad Strategy hit a nerve. Many organizations were scrambling to make sense of a shattered status quo, and Rumelt’s call for clear-eyed, practical strategy felt like a breath of fresh air amid the chaos. Even today, in an age of endless disruption and jargon, his core message holds up: if you want to win, you need to face reality, pick your battles, and act decisively.

Overall, Rumelt’s book is a much-needed antidote to the fog of ‘strategy’ nonsense. It reminds us that strategy isn’t about slogans or vague ambitions—it’s about sharp diagnosis, smart guiding principles, and getting your hands dirty with real, aligned action. If you’re tired of vague corporate pep talks and want something that actually works, this book has your back.
