Coffee is one of the national agricultural commodities in Vietnam. Several problems have existed in the coffee supply chain that threatened Vietnamese coffee's competitiveness. Using the latest version of the Supply Chain Operations Reference (SCOR) model, the study proposes a standard coffee supply chain model with the process elements' detailed level. This proposal model facilitates the investigation of external and internal problems that decrease the coffee supply chain's efficiency in Kontum province, Vietnam. The article also applies the SCOR model for performance measurement in the coffee supply chain. The achieved performance for the whole coffee SC is 68.28 with an average category. Most processes, including Source, Make, Deliver, and Return, have a small performance value with an inferior class. Costs and Agility have the lowest score. The study proposes some recommendations to improve the coffee supply chain's efficiency in Kontum of Vietnam.
