The above was from a real company which went through implementation. They reported the figures above.
If there is an inconsistency it is in that the figures were taken shortly after registration. I have not seen any long term studies. This is not surprising. Many companies are undergoing some type of improvement program at any given time so after implementation the next program can also affect these figures. One of my clients was undergoing TPM, 5-S and QS-9000 (now IATF 16949) implementation at the same time. To try to assign cause to any one of them for better numbers observed is difficult, if not impossible.
When a company goes through the implementation process there is typically a very close look at, and an evaluation of, what is going on. While it happens, it is unusual not to see some type of spike (at least) in numbers. A heightened awareness exists. This is to say the implementation process alone is a learning experience. The question becomes ‘…how long will this last?”
Please do not misunderstand - I don’t believe there are many companies which do not profit from implementation. Often it is hard to translate savings to $, however.
Companies minimize deficiencies in supply and support of products and services.
Companies identify problem areas and address them quicker.
Companies identify customer needs more accurately.
Companies become more consistent in their product and services.
