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 60 parts. A part requires 3 minutes in milling and 8 minutes in finishing. The move time between the two operations for a complete batch is 9 minutes. Under the lean philosophy, the part is produced in a cell that includes both the milting and finishing operations. The operating time is unchanged; however, the bateh size is reduced to 6 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
