Throughout the 1980s and 1990s, Western manufacturers had pursued world-class manufacturing status through a shotgun blast of three-letter acronyms: TQM, JIT, DFM, QFD, QPD and CIM.
The conclusion of most large studies on the successes of these programs has been that only about a third of the companies that attempted to implement the most popular NAOs achieved the results expected-by the companies' own admissions.
