Manufacturing Cycle Efficiency Waymouth Manufacturing operates a contract manufacturing plant located in Dublin, Ireland. The plant provides a variety of electronics products and compo- nents to consumer goods manufacturers around the world. Cycle time is a critical success factor for Waymouth, which has developed a number of measures of manufacturing speed. Waymouth has studied the matter and found that competitive contract manufacturers have manufacturing cycle times (MCE) of about 40 percent. When last calculated, Waymouth's MCE was 35 percent.
Some key measures from the recent month's production, averaged over all the jobs during that period, are as follows:
