The content of the training in this case is determined by the overall business object and the projected return on the investment that is expected to positively impact the company's financial bottom line. Here, the training becomes the tactical deployment of quality tools to improve human capability to solve problems that meet the needs of the strategic plans of the company. Training content beyond those needs becomes lost due to lack of application. Training that provides return on the investment is usually repeated. Management needs to frame the questions so they can be answered with only a little more training than the people have.
Every operation is different, and at different levels of understanding and capability.
So the trianing needs to match that level. When the managers start to ask the questions, then the trianing is there to help the various people, not to impose something on them. Believe me, it works, and works very well. Any training program must be believed in by the participants, otherwise it just becomes a day off work, a social outlet, often counter-productive. Training from the top down is a must.
