Which of the following is considered a key performance indicator in supplier relationship management (SRM)?

On-time delivery is a critical key performance indicator (KPI) in supplier relationship management because it directly impacts the efficiency of the supply chain and affects the overall performance of the business. Timely deliveries ensure that production schedules are maintained, customer orders are fulfilled promptly, and inventory levels are managed effectively. This reliability is essential for building trust and fostering strong relationships with suppliers, as it reflects on their ability to meet contractual obligations and maintain service standards. By monitoring on-time delivery, organizations can evaluate supplier performance, identify potential issues, and work collaboratively with suppliers to improve their processes, which ultimately enhances the partnership and contributes to achieving business objectives.

While supplier training programs, cost of raw materials, and the number of suppliers contracted are important aspects of supplier management, they do not measure the immediate performance and reliability of the supplier in terms of day-to-day operations. On-time delivery stands out as a direct reflection of the suppliers' capability to fulfill their commitments, making it the most critical KPI in this context.
