Which of the following metrics is used to measure customer service level in supply chain management?

Inventory turnover measures how often inventory is sold and replaced over a specific period. While this metric can provide insights into inventory management efficiency, it does not directly assess customer service levels. A high turnover may indicate effective sales but does not guarantee that orders are being fulfilled accurately or timely.

Return on investment (ROI) evaluates the profitability of investments relative to their costs. Although important for assessing financial performance, ROI does not measure customer service or satisfaction. It focuses on the financial returns rather than the quality of service delivered to customers in the supply chain context.

Cash-to-cash cycle time measures the duration it takes for a company to convert its investments in inventory back into cash. While it is useful for assessing liquidity and operational efficiency, it does not reflect customer service performance directly. This metric focuses more on financial aspects rather than the effectiveness of order fulfillment.
