Why this KPI matters
Each extra contact adds cost and erodes trust. Lowering non-resolution rate improves satisfaction and frees capacity for complex issues. It also reduces refunds and escalations.
How to calculate it correctly
- Define resolution. The customer agrees the issue is solved and no further action is needed.
- Count complaint calls. Filter to calls tagged as complaints, not general inquiries.
- Compute the rate. Divide complaints that needed at least one more contact by total complaint calls.
- Segment. Report by product, topic, region, and agent seniority.
How to reduce non-resolution
- Improve discovery. Teach agents to confirm the problem statement and desired outcome before troubleshooting.
- Knowledge at hand. Keep procedures current and easy to search.
- Clear policies. Give agents the authority to solve common complaints in one touch.
- Smarter routing. Send complex issues to specialists right away.
Track first call non-resolution in Klips
- Connect your systems. Bring in call data and ticket data so you can follow cases end to end.
- Model the metric. Flag first calls that later generated a second contact for the same issue.

- Set thresholds. Colour rules flag queues above target.
- Share. Send a weekly report to support and product teams.
Common pitfalls
- Loose tagging. If complaint tags are inconsistent, the metric drifts. Train and audit regularly.
- Overweighting speed. Rushing calls raises recontact. Tie this KPI to FCR and CSAT.
- Ignoring product bugs. Many non-resolutions come from defects. Share patterns quickly with engineering.
