Supplier Corrective Action Request (SCAR): A request initiated between a manufacturer and its supplier, with the purpose of identifying and resolving issues leading to nonconforming products or services. SCARs are essential to maintaining supply chain quality and ensuring customer satisfaction. They also help create shared accountability between manufacturers and suppliers, by providing a framework for managing corrective actions and communicating effectively. By engaging in an open dialogue between suppliers and manufacturers, SCARs can help foster a culture of continuous improvement and innovation within the supply chain.
