Unformatted text preview: M7-22 a. Total cycle time includes all activities that consume time, both valueadded and non-value-added activities. Therefore, all of the above items are included in the total cycle time. b. The non-value-added items include all items except processing. c. Cycle efficiency = Processing time ÷ Total cycle time Cell 1 efficiency = 12.5 ÷ 23.4 = 53.4% Cell 2 efficiency = 16.6 ÷ 24.9 = 66.7% d. Based only on cell cycle efficiency cycle two is most attractive; however, Cell 1 has less total cycle time and less processing time. Therefore, Cell 1 is recommended, especially if some of the non-value-added activities can be reduced or eliminated, thereby increasing the cycle efficiency of this cell.
e. In a lean environment, management is looking for ways to improve efficiency and quality. Regardless of which cell is used, management will be striving to improve the overall cycle time and cycle efficiency. With Cell 1, the most likely candidates for improvement is reducing waiting time, and possibly reducing setup time. All employees in the cell are committed to these and/or other improvements if it is truly a lean production environment ...
