What is it: SMED is the term used to represent the Single Minute Exchange of Die or setup time that can be counted in single digit of minutes. SMED is often used interchangeably with "Quick Changeover". SMED is the practice of reducing the time it takes to change a line or machine from running one product to the next. SMEDs is one of the maun lean production methods for reducing waste in a manufacturing process, by providing a rapid and efficient way of converting a manufacturing process from running the current product to running the next product. This rapid changeover is key to reducing production lot sizes and thereby improving flow (Mura) which is a 'Lean' aim.

Why use it: To minimize machine downtime due to set-up changeover. The advantages of a quick changeover are:

  • Allows smaller economic lot sizes
  • Ability to produce a greater variety of parts
  • Reduces in process inventory
  • Reduces lead times
  • Minimizes machine downtime

Where to use it: For equipment that requires quick turn around times in a lean manufacturing enviroment.

When to use it: SMED and quick changeover programs have many benefits for manufacturers. From reducing downtime associated with the changeover process to reducing the waste created during startup. Additional benefits include:

  • WIP and lot size reduction
  • Finished goods inventory reduction
  • Improved equipment utilization/yield
  • Increased profitability without new capital equipment purchase

How to use it: Shigeo Shingo recognises eight techniques that should be considered in implementing SMED.

  1. Separate internal from external setup operations
  2. Convert internal to external setup
  3. Standardise function, not shape
  4. Use functional clamps or eliminate fasteners altogether
  5. Use intermediate jigs
  6. Adopt parallel operations (see image below)
  7. Eliminate adjustments
  8. Mechanization
