Which of the following is NOT a criterion for evaluating supplier performance?

The correct choice is the one that identifies a factor that is generally not considered a direct criterion for evaluating supplier performance. In supply chain management, the primary criteria for assessing suppliers typically include aspects that directly affect the operational effectiveness and efficiency of the supply chain.

Cost, quality, and delivery time are fundamental performance metrics. Cost pertains to the pricing of goods and services, which affects overall budget and profitability. Quality evaluates whether the supplier provides products that meet the required standards and specifications, directly impacting end-product reliability and customer satisfaction. Delivery time assesses how promptly a supplier can deliver goods, which is crucial for maintaining supply chain flow and inventory management.

On the other hand, employee satisfaction is not a direct measure of supplier performance in the context of supply chains. While it can impact a company's overall environment or the performance of individuals within the company, it does not specifically reflect how well a supplier meets the fundamental requirements of cost, quality, and timely delivery. Consequently, this makes it less relevant as a criterion in the evaluation of supplier performance.
