This UML activity diagram shows the supply chain system. It starts with supplier management and creating orders. After approval, orders go through fulfillment stages, including shipping and inventory updates. They then reach customers, who provide feedback. Unapproved orders are revised for re-approval. This flow of supply chain tasks improves visibility into order handling. It ensures timely processing, inventory tracking, and customer satisfaction. It helps optimize the supply chain. It does this by visualizing order lifecycle stages and decision points for stakeholders.
