                       The present condition and future asset care requirements for the plant and
                     equipment are first established and then developed through the measurement
                     cycle,  which  sets  the  present  and  future  levels  of  overall  equipment
                     effectiveness. Finally, the improvement cycle carries the process forward to
                     the best of  best and on to world class through a continuous improvement
                     ‘habit’ (this concept is fully developed in Chapters 5 and 6).
                       Figure 4.1  shows the application of  Nakajima’s principles to the three-
                     cycle improvement plan. Figure 4.2 shows the driving force behind Japanese
                     TPM, and Figure 4.3 shows the approach pioneered by the Japanese Institute
                     of  Plant Maintenance.

                      Goal:          economic world domination via:
                                            - flexibility
                                            - right products
                                            - right time
                                            - right quality
                                            - right price
                      Trouble-free:   zero defects
                                     zero equipment failures
                                     zero accidents
                      Stockless:     no buffer stocks
                                     no WIP
                      All equals:    total waste elimination
                      TPM viewed as an essential pillar for equipment reliability and product repeatability through
                      people and not the systems alone
