Which of the following metrics is used for operational performance measurement?

Transaction volume is a key metric used for operational performance measurement because it directly reflects the output and efficiency of day-to-day processes within an organization. It indicates the total number of transactions completed within a specific period, providing insights into how well the business is performing in terms of processing customer requests, sales, and overall operational effectiveness.

High transaction volumes can signify that the processes are efficient and that the organization is capable of handling large amounts of business, which can be critical for identifying areas for improvement and operational streamlining. This metric is essential for assessing the capacity and scalability of operations, allowing businesses to make informed decisions about resource allocation and process optimization.

Other options, while important for overall business health, do not specifically measure operational performance in the same immediate and process-focused way that transaction volume does. Employee turnover reflects workforce stability, net profit assesses overall financial performance, and customer acquisition cost evaluates marketing effectiveness, but they do not provide the direct insights into the efficiency and effectiveness of operational processes that transaction volume does.
