INTRODUCTION SMED is a concept that came originally from Japanese Manufacturing Operations and the work of Shigeo Shingo. Companies faced a challenge in how quickly they could change large metal presses over to the next stamping. This process could take days. Shingo found ways to slash thisnumber to mere hours and in some cases to minutes. SMED stands for single minute exchange of dies. This literally was to be able to make the change in under 10 minutes. SMED for us is the opportunity to take timed processes and ﬁnd ways to reduce the time and pressure on what has to bedone while the stop watch is running. This has application in lots of places beyond the factory. What follows is a process to helps us practice SMED. --Tom Curtis
THE 5 R CYCLESReview StepsRemove StepsReorder StepsReposition StepsReplace Steps
REVIEW CYCLEWalk the Process: What are all the steps?This becomes our Baseline and Standard for Improvement. Document them.Start EndTime 1 2 3 4 5 6 Time Document Sequence and Content.Observation and thorough review reveal Hidden Factory.
REMOVE CYCLE Walk the Process: What steps are not needed? Remove them.StartTime 1 X 2 3 4 Keep only required steps. 5 6 End TimeIf a process has not been held to a Standard it may have extra steps.
REORDER CYCLE Walk the Process: What steps should be reordered? Move them.StartTime 3 X 2 4 6 Improve the sequence. 1 5 End Time The original order may provide opportunities for improvement.
REPOSITION CYCLE Walk the Process: What steps could be done before we start the clock? Shift them. 3 X 2 4 Start Time 6 1 Shift Steps out side of the timed process. 5 End TimeMoving Steps before the time starts shorten the time bound process.
REPLACE CYCLE Walk the Process: What steps could be combined or improved? Kaizen them. New New3 X 2 4 Start Time 6 Improve the Steps that remain. 1 5 End Time Kaizen will help us strengthen the required steps.
