One of the lessons the Rudrey team learned while creating training materials was that not all materials work well with all employees. When developing material for administrative areas such as purchasing, sales, quality, and so on, the team found it was sensible not to use manufacturing examples. This proved, in fact, a wise decision. Administrative areas do not want to hear about how lean manufacturing happens on the floor as much as they want to know how it is going to happen in their offices and cubicles. The best approach is to remove all manufacturing examples in the training materials and replace them with administrative examples.
