This measure calculates the rate at which customers leave a company over a given period of time. For example, if 5 out of 100 customers terminate service, the attrition rate is 5%. It is a Process Efficiency measure that helps companies optimize the performance of their "measure and evaluate customer service operations" process by minimizing waste and refining resource consumption.
Customer attrition rate
Process efficiency represents how well a process converts its inputs into outputs. A process that converts 100% of the inputs into outputs without waste is more efficient than one that converts a similar amount of inputs into fewer outputs.
