Which of the following is a key performance indicator (KPI) relevant to supply chain management?

Order fulfillment lead time is a key performance indicator (KPI) relevant to supply chain management because it measures the time taken from when a customer places an order to when that order is fulfilled. This KPI is crucial for evaluating the efficiency of the supply chain and operational processes. A shorter lead time typically indicates a more responsive and agile supply chain, which can enhance customer satisfaction and competitiveness in the marketplace.

In contrast, employee turnover rate, while important for human resource management, does not directly reflect supply chain performance. Equity ratio pertains more to financial health rather than supply chain effectiveness, and market share percentage, although significant for understanding overall market position, does not specifically address the operational aspects of the supply chain. Therefore, order fulfillment lead time is a direct measure of supply chain efficiency, making it the most relevant KPI in this context.
