The author is a businessman who formerly served as Masayoshi Son's secretary and is the writer of the book *Masayoshi Son's Time Management*. There is quite a bit of overlap in content with that book. Rather than providing detailed explanations and examples from PDCA, the story unfolds through hypothetical scenarios, and there are also some stories about SoftBank, so there were many parts where I couldn't figure out where to focus.

This is the best practical book. Now all that remains is to apply it. I feel like I have finally properly grasped PDCA, which I had previously understood vaguely from other books. I plan to apply it immediately to produce results, whether in my personal life or at work. It presents many strategies that are actually helpful, such as the difference between goals and plans, breaking down plans, and quantification. I also thought the illustrations interspersed throughout were very appropriate to

A must-read for working people! A must-read for students! A must-read for just playing people!

This is not just a book to read; it is a secret guide to action. "Execute the ideas that come to mind one by one, identify the method with the best cost-effectiveness, and allocate resources only to it.

The PDCA method—Plan-Do-Check-Act—is indeed a management technique that many people are now familiar with. However, it is also true that few actually understand its practical logic and apply it in the field. This book tells the story of SoftBank, which has become a world-class enterprise by utilizing this very PDCA method. In particular, the author explains that SoftBank Chairman Masayoshi Son’s unique management technique, known as "High-Speed PDCA," became the driving force behind the

We often see people blaming their own abilities when things go wrong or stall while running a business or working, and we ourselves are not free from that self-blame. What I strongly felt while reading this book is that while competence is important, methodology is also crucial for solving problems. We have studied extensively on how to create effective plans. However, when things do not go according to plan, we become frustrated, knocked down, and the matter ends with the word "failure." The

Personally, I was in charge of management evaluation at my company for several years. While writing performance reports, one of the things I heard from a consultant was PDCA. I had heard of the "introduction, development, climax, conclusion" structure, but PDCA? I learned it stands for Plan-Do-Check-Act. At the time, I understood it simply as a method for writing performance reports. However, encountering PDCA again through this book, I realized anew that it is not merely about writing reports,

This book discusses PDCA using the success story of SoftBank, Japan's largest IT company. Business and marketing professionals have likely heard of PDCA more often. However, actually applying and implementing it in the workplace is not easy. This may be because readers do not know the specific details of how to put it into practice. Although I had heard the term PDCA and what it entails, I did not know the specifics, so I wanted to use this book as an opportunity to learn more about it. In

The book describes PDCA, a condition for ultra-fast growth, as part of Chairman Masayoshi Son’s SoftBank 3 Principles: High-Speed PDCA. PDCA can cultivate the power of independent thinking, the power to utilize numbers, the power to eliminate waste, high motivation, and a mindset that does not fear failure.
