First call resolution (FCR) measures the percentage of calls where the caller’s issue is completely resolved without requiring a follow-up contact. It is a key indicator of both operational efficiency and customer satisfaction.
How is first call resolution measured?
FCR can be measured through post-call surveys asking if the issue was resolved, by tracking whether the same caller contacts again within a defined period, or through disposition codes assigned at call completion. Each method has trade-offs between accuracy and practicality.
Why does first call resolution matter?
High FCR means callers get what they need quickly. Low FCR indicates problems that create repeat contacts, wasting both customer time and operational resources. For AI voice agents, FCR directly measures their ability to handle issues end-to-end without passing them to a person.
First call resolution in practice
A team tracks FCR for its AI voice agent on appointment scheduling calls. Analysis of the calls that needed follow-up shows most involve insurance verification, which requires information the agent cannot access. Connecting the agent to the insurance system lets it resolve those calls on the first try.
