What is Calls Per Minute?

Calls per minute (CPM) is a metric used to measure the efficiency and productivity of call centers or any environment where calls are made or received. It represents the average number of calls handled per minute over a specific period. This metric is crucial for understanding the performance of call center agents, optimizing resource allocation, and improving customer service. By monitoring CPM, organizations can identify trends, make data-driven decisions, and implement strategies to enhance overall efficiency.
