"As long as Toyota is continually identifying "anomalies" in the manufacturing process, every single defect is seen as an opportunity to make the process better. There are, in effect, a set of rules that ensure that this happens. For example, an employee must never add value to a part until it is ready to be used in the next step of adding value. It must be done in the same way, every time. That way managers know, definitely, that the value-adding step worked with the next step in the process. That creates an environment of repeated scientific experimentation. Each time it's done the same way constitutes a test of whether doing it that way, to those specifications, will result in perfection every time. For Toyota, the theory was embodied in the set of processes they developed to lead to defect-free manufacturing. Each activity can be seen as an individual if-then statement: "If we do this, then that will be the result." Through this theory of manufacturing, the quality movement was born. As a consequence, the Americans took what they'd learned from their Japanese competitors to heart and the US automobile industry today churns out very reliable cars. Innovation, in a very real sense, exists in a "pre-quality revolution" state. 1 Managers accept flaws, missteps, and failure as an inevitable part of the process of innovation. They have become so accustomed to putting Band-Aids on their uneven innovation success that too often they give no real thought to what's causing it in the first place."
