Well actually it isn’t a secret – it is in fact the Toyota Production/Management System. Maybe, if people assume the TPS is about improvement in the factory alone, then they could miss the true importance as the management system that it is. So I quibble a little bit with the title but this is actually a good article by John Teresko, Toyota’s Real Secret: Hint, It’s Not TPS:
Toyota’s time-to-market metrics are one measure of its lean product development accomplishments. For example, only 22 months were required to bring Toyota’s U.S.-developed Tundra pickup truck from styling freeze to start of production, says Yuichiro Obu, executive chief engineer at Toyota’s Technical Center in Ann Arbor, Mich. That contrasts with the 30 to 40 months that were commonplace in the U.S. during the late 1980s. Toyota averages 24 months, regularly reaches 15 months and has had instances as low as 10 months.
One secret behind Toyota’s lean product development success is the same one supporting TPS — the Toyota Management System and its dedication to continuous improvement. Morgan and Liker emphasize Toyota’s commitment to “the importance of appropriately integrating people, processes, tools and technology to add value to the customer and society.”
To me saying the Toyota Production System is only about manufacturing is like saying “lean manufacturing” is only about manufacturing. The article is certainly correct in stating that moving the thought process to a systems view that incorporates the entire system is key – as Dr. Deming said in 1950 and I think Toyota has understood perfectly well for decades. Maybe I am being sloppy in not separating TPS from Toyota Management but I think most people think of TPS as Toyota’s overall management system.
