I have really been enjoying the writings of some of the early Toyota executives and this book is no exception. The Birth Of Lean is a compilation of interviews conducted with several of the high-ranking officials at Toyota including Eiji Toyoda himself.
Even though this book is titled "The Birth of Lean" the conversations contained within really do not resemble what much of today's "Lean" looks like. So much of the focus of this book is about what problems Toyota was facing and how they had to struggle everyday to overcome. They didn't have a "toolbox" and created things as they went. They didn't have an improvement strategy, only a vision for perfection and a diligent eye on the prize.
Even though Deming is not mentioned too much in this book, other than how Toyota won the Deming Prize in 1965, you can feel his influence. Deming's very first principle of management is create constancy of purpose towards improvement. The Toyota Executives interviewed in this book certainly had that constancy of purpose in every one of their interviews. No matter what the problem was, there was an unwavering sense of urgency to correct it. And even when there seemed to be no problem, Ohno challenged his managers. As an example, one of the interviewees early in his career didn't understand Ohno's urgency with creating kanban. He was happy simply reducing or controlling inventory. He highlights his learning journey from complacency to full understanding of not just kanban, but the system.
Today you hear, too often unfortunately, how "lean is for speed and 6 sigma is for quality." Last I checked, 6 Sigma was formalized somewhere in the mid-1980's. Much of "The Birth Of Lean" discusses how TQM & TQC were critical in the formation of Toyota's quality success a full 20 years prior to 6 Sigma. In at least 2 (maybe more) interviews in this book, the interviewee discusses how TQM/TQC were paramount to the success of the Quality that is built in to Toyota Vehicles. Toyoda-san addresses the Quality Movement in both of his interviews. Although he didn't have intimate working knowledge, he saw the results and knew the system worked. He allowed Ohno, and others, manage it.
One thing that I continue to learn is how respect for people, in the early Toyota culture, is not "be nice to everyone and let them have a say". Ohno seemed to be a considerable tyrant; however, he was a greatly respected tyrant. He set high expectations for all his employees but for his management he was even tougher. One of the interviews, the interviewee told a story of how Ohno referred to him as "an idiot". I have to assume that some of the language (ie idiot) has changed, but I also have to assume that the message has not - "Improve or Die"
These interviews we're done mainly in Japanese and the translation in the book is excellent. The Editors advised early on that they had to make some changes to the sequencing of some of the interviews, but whatever they did worked as the book seems to flow very nicely. Like many of the other books chronicling the original Toyota masters, The Birth Of Lean is a book that is definitely geared for Executive Leadership or for people who are just genuinely interested in how the Toyota System was formed. This is not an entry-level book by any means; however, if you enjoy the classic writings of Shingo and Ohno, you will enjoy this book from some of Ohno's lesser-known disciples.
