When we say lean, we think that is a process centered on preserving value with less work. Lean manufacturing is a management philosophy derived mostly from the Toyota Production System (TPS) and identified as "lean" only in the 1990s (Womack, Jones, Roos, 1990; Holweg, 2007). Lean manufacturing is a concept, developed mostly in automotive plants. It is much more than tools and boards. Comparing building of a racket or plane with automotive industry we are determined to say that is easier for automotive because are much simpler than a racket also the number of component parts is about 5000 for a vehicle comparing to 60000 for a racket. The thinks are quite reverse because a rocket is built, generously, in few months, automotive industry builds from 500 to 1000 units each shift, all of them can be different type. Imagine 10 options with possibility OK and NOK, resulting 2**10 different types. In this situation, it is not easy to build these 1000 cars in 8 hours without a perfect logistic and discipline. Lean manufacturing is a concept that reorganize not only the material flow, technology, the tools and devices, but also the behavior, the thinking, the culture.
