Metrics #1. Active waiting calls

Active waiting calls measure the current volume of calls waiting in the queue versus those being actively handled by agents. It’s a critical metric that reflects the call center’s ability to manage incoming call traffic effectively and maintain service levels. An optimal balance ensures that customers are connected to an agent as swiftly as possible, enhancing their overall experience.

When active waiting calls are low, it indicates a highly responsive and efficient call center operation, directly contributing to customer satisfaction by minimizing wait times. Conversely, high volumes of waiting calls can lead to customer frustration, potentially affecting their perception of the brand negatively and increasing the likelihood of call abandonment.

The formula for calculating active waiting calls is:

Percentage of active waiting calls = (Total number of calls on hold / Total incoming calls) * 100

For example, if a call center receives 100 calls in an hour and 80 of those are immediately connected to an agent, there are 20 active waiting calls. So, the percentage of active waiting calls is 20%.

Ways to improve

• Optimize staffing: Ensure enough agents are scheduled during peak hours.
• Leverage call routing: Use IVR systems to direct callers to the appropriate agent or department efficiently.
• Offer callback options: Reduce immediate demand by giving customers the option to receive a callback when an agent becomes available.
