A changeover is the work required to change a specific machine, resource, work center or line from making the last good piece of an item to making the first good piece of another item. That means that if the first good piece after the changeover is not good the changeover is not complete.
1. Teardown of equipment after production is complete.
2. Preparation of equipment for the next scheduled item.
