Average resolution time (ART)

The average resolution time in call centers varies depending on the complexity of the service issue and the ratio of available call centre agents to queued tickets for the given period.

If the Average Resolution Time (ART) increases, the call centre manager should investigate the underlying problem and try to solve it.

It could mean that the support crew needs more aid and training to deal with increasingly complicated client concerns or that there is a lack of coordination between the support team and those brought in to help with complex problems, such as engineering challenges.
