Calculate$$Lead TimeFlint 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 $85$ parts. A part requires $3$ minutes

in milling and $7$ minutes in finishing. The move time between the

two operations for a complete batch is $8$ 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.
