<br />At first, Taiichi Ohno, who helped create the Toyota Production System, didn&#39;t want to write it down because he was afraid people would only pay attention to the tools and theories. When he finally wrote it down, he described it as a house because a house can be considered as a system. If you remove any supports holding up the roof, the roof and everything connected to it will fall down. One of the students of Ohno said that Toyota made a mistake when they named it the Toyota Production System. Instead, Toyota should have named it the Thinking Production System because the main purpose was to encourage people to think, and people are the most important part of the system.
