What are the efficiency and balance delay of the solution found? Q3: he trim line at PW is a small subassembly line that, along with other such lines, feeds into the final Chassis line. T entire assembly line, which consists of more than 900 workstations, is to make PW's new E cars. The trim line itself involves only 13 work elements and must handle 20 cars per hour Work elements data are as follows
