The Supply Chain Operations Guide Model, or SCOR, was launched by the Supply Chain Council to provide all companies a construction or tool they can use to boost their company's source chain internally and externally. It allows resource chain managers to investigate their current situations as well as guide them to provide chain decisions for advancements and future resolutions. A significant strength of the SCOR model is the fact it could be used across sectors and applied to a variety of different companies. There are five levels in the SCOR model. The first level, the process types, includes plan, source, make, deliver, and return. These process types illustrate the overall scope and content of the SCOR model.
