Struggling to persuade others, nail a presentation, or make sharp decisions? Logical Thinking by Katsumi Nishimura breaks down the core skills you need to build rock-solid logical reasoning, starting with the game-changing MECE (Mutually Exclusive, Collectively Exhaustive) principle to eliminate gaps and redundancies in your thinking. Nishimura walks you through foundational frameworks like triangular logic (claim, evidence, data) and the two key reasoning methods—inductive and deductive—to structure your arguments clearly. You’ll also learn practical tools like logic trees to organize messy data, how to prioritize tasks using QCD (Quality, Cost, Delivery) and time-blocking for maximum efficiency, and communication tricks to turn you into a clear speaker and active listener. Packed with real-world business examples from companies like Asahi Beer, Microsoft, and Uniqlo, this book turns abstract logical concepts into actionable steps, helping professionals cut through confusion, work smarter, and communicate with confidence.
