                   Thus the benefit of  increasing the average OEE up to the best of  best OEE
                   (approximately 79 - 55 = 24%) is equivalent to an extra 370 units per week.



                   6.7 Assessment of the six  losses
                   Following an initial visit to the machine and a 'brainstorming'  session with
                   the operator and maintainer, the problems identified for the M201 are as
                   follows:

                        abnormal operation
                        electrical power loss
                     0  vibration
                     0  no airsupply
                     0  tooling performance affected
                        long cycle time
                        initial start-up procedure
                        excessive component loading time
                        slideway damage
                        operational safety
                     0  no reference domentation
                     These problems and issues have been allocated to the six losses in Figure
                   6.15. Part of  the loss assessment record is shown in Table 6.4.
