There are many standard traffic measurements (performance metrics) that can be performed on a call center to determine its performance levels. However, the most important performance measures are:
• The average delay a caller may experience whilst waiting in a queue
• The mean conversation time, otherwise referred to as Average Talk Time (ATT)
• The mean dealing time, otherwise referred to as Average Handling Time (AHT – equal to ATT plus wrap-up and/or hold time)
• The percentage of calls answered within a determined time frame (referred to as a Service Level or SL %)
• The number of calls / inquiries per hour an agent handles (CPH or IPH).
• The amount of time spent while an agent processes customer requests while not speaking to a customer (referred to as Not Ready time/NR, or After Call
Work/ACW, or Wrap-Up.)
• The percentage of calls which completely resolve the customer’s issue (if the customer does not call back about the same problem for a certain period of time, it is considered a successful resolution or FCR – First Call Resolution).
• The percentage of calls where a customer hangs up or “abandons” the call is often referred to as Total Calls Abandoned or Percentage of calls abandoned. Calls are often abandoned due to long hold times when a call center experiences a high call volume.
• Percentage of time agents spend not ready to take calls, often referred to as Idle Time.
• Quality Assurance monitored by a quality assurance (QA) team.
