Service Level Adherence

Percentage of customer contacts answered within the target response time

What is Service Level Adherence?

Service level adherence is the percentage of contacts answered within the target time. It shows how well a service meets its promise on responsiveness.

A typical service level might be a set share of calls answered within a set number of seconds, and adherence shows whether that is being met.

How to calculate it

Divide contacts answered within the target time by total contacts offered, and multiply by 100.

For example, if 850 of 1,000 calls were answered within 30 seconds, service level adherence is 85%.

Set targets by channel, and look at performance by time of day, since averages can hide peak-time problems.
