Sakichi Toyoda is often referred to as the father of Japanese industrial revolution. He is also the founder of Toyota Industries Co., Ltd. He created a variety of weaving device. The most famous invention is the automatic power loom in which he applied the principles of Jidoka (autonomous automation). Jidoka principle, which means that the machine stops itself when the problem occurs, then became part of the Toyota Production System.
Toyoda developed the concept of 5 why: When a problem occurs, ask 'why' five times to try to find the source of the problem, then put into place something to prevent these problems from recurring. This concept is used today as part of implementing lean methodologies to solve problems, improve quality and reduce costs.
