Problem Identification
Doug Friesen, Toyota Motor Manufacturing, U.S.A. (TMM)’s manager of assembly, has an urgent issue on hand.

Moving the cars to the overflow lot has eliminated the involvement and teamwork of the assembly line. Furthermore, time has been allowed to pass, compounding the problem. The cause of the problem is still undetected. Although the time taken to get...
