Résumé de Good Strategy Bad Strategy

In *Good Strategy Bad Strategy*, Richard Rumelt argues that most corporate strategy documents are not strategy at all but goal statements, slogans, or financial targets dressed up as planning. Real strategy, he contends, begins with a diagnosis of the situation, a guiding policy for dealing with it, and coherent action that follows from both. He calls this the "kernel" of strategy and returns to it throughout the book. Rumelt, a UCLA professor and consultant, illustrates the kernel with cases ranging from Xerox's failure to exploit its own inventions to the rise of Apple under Steve Jobs, and from the U.S. invasion of Iraq to Walmart's logistics-driven advantage. He contrasts these with "bad strategy," which he characterizes by fluff, failure to face the actual problem, mistaking goals for strategy, and bad strategic objectives. He also criticizes the use of generic frameworks such as the balanced scorecard and mission statements when they substitute for hard choices. Another key idea is the "crux," the specific obstacle that must be overcome, drawn from Clausewitz. Rumelt further discusses sources of power, including leverage, proximity, and the use of design, and warns against mistaking financial planning for strategy. He examines why good strategy is rare: it requires honest diagnosis, difficult choices, and sustained focus. The book is part critique of modern management practice and part manual for thinking clearly about competitive problems. It draws on business history, military theory, and economics to show how leaders can identify the few critical issues that determine success or failure and concentrate resources there rather than spread them thin across competing priorities. Rumelt's prose is direct and often skeptical of fashionable management advice. Published in 2011, the book has become a standard reference for executives and students seeking a rigorous alternative to goal-setting and vision statements, though its case studies and arguments are drawn from real companies, historical events, and the author's consulting experience.
