Achieving Changeover FlexibilityBrigham Young University Prepared by: Kortney J. Jurado
What will be covered… • Changeover Flexibility Defined • How can this help our firm? • Real world example • How do we get there? • Exercise • Summary
Changeover Flexibility Defined The ability to switch from making one product to another one without incurring high setup times
Production Lead Time • Queue: Time waiting before the operation begins • Setup: Time getting ready for operation • Run: Time performing operation • Wait: Time waiting after operation ends • Move: Time physically moving between operations
Brainstorming Exercise How will our company benefit from achieving changeover flexibility?
Current Market Demands • Less costly • Higher quality • Shorter lead times • Increase in average mix
The Why… • Customers increasingly demand more customized products • Reducing setup times allows us to be more responsive to customer needs • If setup times are reduced at the bottleneck, capacity increases • Able to convert runs into smaller lot sizes
Real World Example: • Dr. Shigeo Shingo’s success at Toyota with “single digit setups”
Single Minute Exchange of Die (SMED) • Identify internal and external setup activities • Determine internal events which can be converted to external activities • Reduce time it takes to perform those internal and external events • Repeat the process
Identify Internal and External Events • External: can be done while machine is running previous job • Ex: staging materials, getting specs and drawings • Internal: require the use of the machine • Ex: removal of the die
Determine Internal Events That Can Be Converted to External Activities • What changes can we make to our process or machinery? • Example: A company modified the machine so that the mount and the die could be removed as one piece
Reduce Times for Both Internal and External • Internal tasks will remain our constraint • Why do we need to reduce the time on our external activities?
Repeat the Process • What else can be removed from internal setup? • Can reduce a task by a few more seconds? • What else can we do to reduce our setup times?
Applying Shingo’s Method to Our Setups • Split into groups and take a setup through Shingo’s four steps
What did we learn? • How can setup time be reduced? • What can we do to make it easier, simpler, and safer? • Can we do something more?
Another Tool: 5-S • Sort • Simplify • Scrub • Standardize • Sustain
Sort • Separate items that are used daily from those that are used occasionally • Remove little used items from your workspace
Simplify • Set in order • Arrange items so they are easy to see, use, and put away • Ex: carpenter’s shop • If tools are used sequentially, place them in that order
Scrub • Clean the work area • You will not need to be cleaning during a changeover
Standardize • Sort, • Simplify, • And Scrub DAILY • Make it a habit!
Sustain • Continue to continue • There will be changes over time • Start from the beginning again and again
Exercise • Divide into groups • Create a plan to run your work area through the 5-S process • Discuss your plan with your teammates
What did we learn? • How does 5-S affect changeover flexibility? • How can our setup times benefit from the use of this tool?
Evaluation • List and explain the steps to SMED • List and explain the steps in 5-S
Summary • Changeover Flexibility = • Profits • Competitive Advantage • Greater responsiveness to market demands • Increased capacity
