Original Equipment Manufacturer (OEM) An OEM (original equipment manufacturer) is a company that build a product that it sells under its own company name. An air compressor manufacturer is an OEM, and the manufacturer of the PLC inside that air compressor is an OEM. Outage A term used in some industries (notably power generation), which is equivalent to a planned shutdown. A period of time during which there is a complete planned production stoppage. Outsourcing Shifting of production work or support activities to an outside (third-party) supplier. To get an idea of total efficiency, the overall equipment effectiveness is multiplied with system utilization. Remark: In case of product variations in one production line, resetting the production line could be necessary. If this can be done without a stop, it is probably translated in speed or yield losses. If this is done during a stop, it could be considered as planned although it can results in a forced (incurred) downtime elsewhere in that production line, which can be considered as unplanned. Now, if the set-ups / resets are foretold / preplanned, then they are part of the planned downtime losses and the issue becomes what was the magnitude, frequency of those set-ups / resets actually when compared to what was allowed for and planned. So, planned resetting can be considered as planned downtime loss, but the next issue
