Step-by-step explanation:
The answer to the question 'Which of the following is not one of the processes in the SCOR model?' is a. sell. The SCOR model, which stands for Supply Chain Operations Reference model, is a management tool used to address, improve, and communicate supply chain management decisions within a company and with suppliers and customers of a company.
The SCOR model includes the following five core management processes: Plan, Source, Make, Deliver, and Return. These processes represent the steps required to efficiently manage the supply chain from beginning to end. 'Sell' is not one of the core processes identified in the SCOR model, whereas 'plan', 'make', and 'return' are indeed part of the model.
