Quick Changeover (QCO-SMED)

Use the Quick Changeover (QCO-SMED) form to compare the internal and external activities of process changeover, or setup, for both current and improved states.
Use the Shigeo Shingo approach to categorize the setup activities. The primary goal is to reduce internal setup time, which reduces the amount of non-productive process time and enables more setups, smaller run batches, and improved flow.
Must be done while the process is stopped.
Can be done while the process is running, either before or after performing the setup.


  1. Enter the project details.
  2. Enter the workstation details.
  3. Enter the changeover data.
  4. In the Initial State and Improved State tables, enter each activity and define as Internal or External.

    If an element is partly internal and partly external, enter it twice with the appropriate data. For example, Inspect (internal) = 4 minutes and Inspect (external) = 8 minutes.

  5. Summarize your conclusions.
