Derived from the Go term for post-game analysis, 'Review' has evolved into a structured, evidence-based method for turning past experiences into actionable growth—for both individuals and organizations. Popularized by Lenovo founder Liu Chuanzhi, this framework goes beyond generic work summaries: it requires teams to revisit goals, compare actual outcomes, dig into root causes of gaps, and translate lessons into concrete next steps. Unlike routine summaries that focus on performance bragging, Review prioritizes learning, collaborative discussion, and factual accuracy. Drawing on real-world examples from the U.S. military’s After-Action Reviews (AAR), British Petroleum’s project post-mortems, and Lenovo’s decades of corporate practice, this book breaks down how to implement Review across personal tasks, team activities, large-scale projects, and strategic planning. It addresses common misconceptions, provides step-by-step guides, and shows how to embed Review into company culture to build a self-improving learning organization that avoids repeating mistakes and drives consistent performance gains.

Essential Thinking

Soichi Yonezawa

Essential Thinking by Soichi Yonezawa is a practical, actionable guide to cutting through surface-level confusion and solving problems at their root. Starting with the critical link between precise language and sharp thinking, it explains how vague communication and unexamined assumptions derail personal and professional interactions. The book breaks down 9 common thinking traps—from mental laziness and cognitive distortion to emotional bias and responsibility avoidance—that keep people stuck in cycles of wasted effort. It then outlines 9 targeted strategies to escape these traps, such as zero-based thinking, layered root cause analysis, and introspection for emotional regulation. Yonezawa emphasizes that essential thinking isn’t about overthinking; it’s about building a healthy cycle of action, feedback, and intentional reflection. Packed with relatable workplace and daily life examples, this book equips readers to make smarter decisions, avoid unnecessary mistakes, and cultivate a habit of getting to the heart of every challenge.
