From the author:

This book contains virtually all of my knowledge on the practical implementation of work standardization according to the TWI program. I believe that the time you spend reading this book will not only equip you with what to do to implement work standardization, but I hope you’ll also learn how to do it and understand why it’s worth doing this way.

Book reviews

I think this is an excellent guide to creating standard work using the TWI approach. I watched some videos on TWI Job Instrutions, but didn't really get it. The author provides 41 tips to consider when writing up the standard work. In true TWI fashion, he also provides the reasoning behind the tips. Providing the reason makes it much clearer what you are trying to accomplish. The author obviously has lots of experience implementing TWI JI and JM. He does a nice job occasionally injecting his own feelings or experiences. I find it helpful when someone who is really experienced can say "this is the most common mistake that I see people make." The book takes you step by step through the process of writing up standard work. It also talks about how to improve the standard work. It then gives a plan on how to start implementing standard work. Finally it gives the instructions for how to run your own TWI training course. I think I will be referring to the book often as I start to try to install standard work in my department. With this clearly laid out model that is proven to work (it helped the US win WWII), I have a much higher degree of confidence in my chances of success.

"Standardized work with TWI has seemed to me a book of great interest, I recommend reading it to all the professionals who dedicate themselves to the development of continuous improvement in companies."

A book about TWI – preface

The strength of any company depends on utilizing the potential of its employees. People have the primary impact on the quality of products and services, as well as on process efficiency. People are usually responsible for errors, failures, shortages, and downtime. Automation, which displaces human labor from direct manufacturing processes, does not solve this problem. It merely relocates the potential for human error. After all, it is humans who must operate, set up, or retool an automated workstation. People will always be part of manufacturing processes, so we must work to prevent their errors. I believe it is possible to eliminate all human errors from any process. This is not a simple task, as it is not simply a matter of purchasing error-proof equipment (Poka Yoke). This requires a change in the organizational culture and approach to managing employee competencies. This requires continuous and daily work on people’s attitudes.

In my opinion, work standardization is the key to eliminating human error. Standardization is not just about creating work instructions. It’s a comprehensive approach that builds employee awareness through training, and develops their skills in work improvement through kaizen sessions. I believe that all human errors in manufacturing processes can be eliminated through work standardization. In this book, I will explain what the TWI program is and how its presence has influenced people’s understanding of work standardization. I consider the TWI program to be one of humanity’s most important achievements in management. Yes! Work standardization according to TWI is the best currently known method for effectively managing employees at all levels.
