The Management Brief | Transforming from GM Executive to Toyota Leader

44 minutes

Josh Howell, LEI President, and Mark Reich, LEI Chief Engineer Strategy, talk with Carl Klemm, former General Motors and Toyota executive (including six years as President and CEO of Toyota Motor Manufacturing Poland). After retiring from Toyota in 2015, Carl founded Carl Klemm Management Solutions so he could continue to work with companies and share what he has learned about lean through the years.

This month The Management Brief explores how leaders transform and rethink traditional management approaches to achieve success with lean. Carl’s management thinking has certainly changed since he started as an apprentice with General Motors. Early in his career at GM, he saw that virtually everyone had a “dreadful” relationship with industrial engineering that wanted to improve processes, and then, when studying NUMMI, the Toyota-GM joint venture, realized that did not have to be the case.

After 24 years Carl left GM, joined Toyota, and was excited by what he could learn there. “I really wanted to join. I wanted to learn. I wanted to understand. I wanted to be able to do it, not just understand it, be able to do it and make it work.”

Carl, author of The Balance of Excellence,1 also discussed:

Toyota compared to GM: Senior executives at Toyota were more communicative with employees down through the organization, more management maturity on Toyota shopfloors, the long-term perspective of Toyota management, and “the planning and strategic activity is much more intense” at Toyota.

Importance of management to achieve results and develop people concurrently and in harmony: “Management’s job is to keep those wheels aligned. That’s a true key difference between Toyota and other organizations I’ve come across.”

The operational and cultural benefits of pulling the andon: The process of pulling the andon allows standard work and throughput to be maintained while a problem is addressed, and frontline members can see that they immediately get support for their work rather than “waiting for ages” for assistance to come.

Four levels of management maturity: The four levels of maturity — reactive, stabilizing (getting control of processes), proactive (beginning to do kaizen), and progressive — ultimately get leaders to a place where they understand that the organization underneath them is independently performing kaizen and they can focus on what the organization needs to achieve “in the coming five, 10, 15, 20 years. And, of course, Toyota does that. Toyota is thinking 25, 30 years ahead always.”

Advice for those getting started with lean: “First establish the situation of mutual trust and respect, because without that everything is difficult.”
