Book summary
Good Strategy Bad Strategy by Richard Rumelt explains that a good strategy is a coherent set of actions rooted in a clear diagnosis of the most important challenges in a situation, followed by a guiding policy and focused resource deployment to leverage strengths and overcome obstacles. In contrast, bad strategy is a collection of vague aspirations, wishful thinking, and buzzwords that fail to confront real problems or concentrate effort. Through numerous case studies from business, military, and government, Rumelt demonstrates how kernel-based good strategy delivers real progress while bad strategy creates the illusion of progress without substance. The core argument is that true strategy is about making hard choices and focusing resources on what matters most rather than pretending everything can be achieved at once.
