First-contact resolution

The share of issues solved on the first interaction — no callbacks, no escalations.

In one sentence

First-Contact Resolution (FCR) measures the share of customer issues resolved during the first interaction, with no re-open, follow-up or escalation needed.

When it matters

Stronger predictor of CSAT than handling time. An AI deflection drop with FCR also dropping is a regression in disguise.

A real-world example

After switching from semantic-only to hybrid retrieval, an industrial pump manufacturer saw FCR rise from 51% to 78% in three weeks.
