What is autonomous resolution rate?
By Lewis CrookPublished
Autonomous resolution rate is the share of calls fully resolved by an AI system without human involvement and without the customer re-contacting for the same intent within a defined window (typically 7 days). It is a stricter alternative to containment rate.
Autonomous resolution rate is containment rate that survives re-contact.
Why it matters for enterprise CX leaders
- Autonomous resolution rate eliminates the most common containment overstatement: counting calls that returned for the same issue.
- It is the metric most defensible to finance and to regulators because it tracks outcome, not handling.
- Most vendor materials do not quote it because it produces lower numbers than containment.
Frequently asked questions
- How is autonomous resolution rate calculated?
- Contained calls minus calls that re-contacted for the same intent within the defined window, divided by total in-scope calls.
- What window should be used for re-contact?
- Seven days is the most common internal standard. Some teams use 14 days for intents with longer resolution cycles such as claims or disputes.
- Is autonomous resolution rate the same as first-call resolution?
- Related but not identical. First-call resolution traditionally applies to human-handled calls; autonomous resolution rate is its automation equivalent and uses a comparable re-contact window.
