The Toyota Way: 14 Management Principles From the World's Greatest Manufacturer

by Jeffrey K. Liker

Let's say you bought a book on creating one-piece flow cells or perhaps went to a training class or maybe even hired a lean consultant. You pick a process and do a lean improvement project. A review of the process reveals lots of "muda" or "waste," Toyota's term for anything that takes time but does not add value for your customer. Your process is disorganized and the place is a mess. So you clean it up and straighten out the flow in the process. Everything starts to flow faster. You get better control over the process. Quality even goes up. This is exciting stuff so you keep doing it on other parts of the operation. What's so hard about this? I have visited hundreds of organizations that claim to be advanced practitioners of lean methods. They proudly show off their pet lean project. And they have done good work, no doubt. But having studied Toyota for twenty years it is clear to me that in comparison they are rank amateurs. It took Toyota decades of creating a lean culture to get to where they are and they still believe they are just learning to understand "the Toyota Way." What percent of companies outside of Toyota and their close knit group of suppliers get an A or even a B+ on lean? I cannot say precisely but it is far less than 1%.
