Activities that setup or prepare production equipment for the next job while the equipment is still processing the current job. External activities avoid setup downtime, as opposed to internal setup activities that require the equipment to be idle. Moving set-up activities from internal to external in order to reduce machine down time is a central activity of set-up reduction and SMED. Also called OED - "outer exchange of die"
