• Playthings, a toy manufacturer specializing in toys for toddlers, is considering switching to a JIT manufacturing process. The CEO has been talking with the production consultants, who tell her that a new philosophy must be embraced: If a defective part of an out of-control process is detected, no more units should be made until the process is corrected. The consultants estimate that the production process may occasionally be shut down anywhere from 30 minutes to 7 hours.
