Quick Changeover & SMED are invaluable tools in the pursuit of flow.

Quick Changeover (QCO) can be achieved by the system Shigeo Shingo developed in the late 1950-ies called Single Minute Exchange of Die (SMED). Some benefits of QCO are:

- reduced lead times;
- reduced lot sizes;
- on time delivery; and
- reduced inventory
