Quick Changeover (SMED) As lean production is dependent upon small lot sizes‚ small lot sizes are dependent upon quick changeovers. If set-ups or changeovers are lengthy‚ it is mathematically impossible to run small lots of parts with low inventory because large in-process inventories must be maintained to feed production during changeovers. For example‚ large stamping dies commonly took hours to change until the development of quick die change methods (Single Minute Exchange of Die‚ or SMED).

For example the
