Calculate Lead Time Flint 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 30 parts. A part requires 5 minutes in milling and 7 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 4 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. Traditional Philosophy Lean Manufacturing Philosophy Value-added time Value-added time 12 12 min Non-value-added time 1 353 min 36 min Total lead time 365 48 min Value-added ratio (as a percent) II INS Check My Work Recall that lead time can be classified as 1. Value-added lead time, which is the time spen 2. Non-value-added lead time, which is the time is moved from one process to another. In this exercise for Traditional: onverting raw materials into a finished unit of product. while the unit of product is waiting to enter the next production process or
