Jackson fabricators inc. machines metal parts for the automotive industry. under the traditional manufacturing approach, the parts are machined through two processes: milling and finishing. parts are produced in batch sizes of 40 parts. a part requires 6 minutes in milling and 8 minutes in finishing. the move time between the two operations for a complete batch is 5 minutes. under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. the operating time is unchanged; however, the batch size is reduced to 5 parts and the move time is eliminated. determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methods. if required, round percentages to one decimal place.
