SLA breach rate is the rate of tickets handled that do not meet the time commitment (SLA) in a period — if committed to responding within 15 minutes but 20% of tickets are late, the breach rate is 20%. This is an index measuring the reliability of customer service operations: a high breach rate means promises to customers are frequently broken, and reputation decreases. Monitoring and improving breach rate is the foundation of quality (see What is SLA). Zenify recorded that businesses reduced breach rates and increased conversion rates by 21% (approved).
TL;DR
- Breach rate = rate of tickets that do not meet the time commitment.
- Whatever commitment is measured, measure that commitment (response/resolution).
- Target: <5% is good, don't ask for 0% unless there is a reason.
- High Breach = frequent broken promises, loss of credibility.
- Improvement: correct SLA, correct resources, early warning.
What is SLA breach rate
SLA (Service Level Agreement) is a commitment to processing time:
FRT: reply in 15 minutes.
Resolution: resolved within 24 hours.
Breach rate measures the percentage of tickets that do not meet commitments:
Breach rate = (SLA violation tickets) / (Total tickets) × 100%
Example: 100 tickets, 15 late reply tickets.
Breach rate = 15% — meaning 15% of promises are broken.
Why must you monitor breach rate?
Measure true promise: the customer accepts the commitment, breach means not keeping the promise.
Early warning: Increased breach is a sign of overload before quality collapses.
Improve in the right places: know which step is late (feedback or resolution).
Avoid "guessing": If you don't measure, you won't know how many times you're breaking your promises.
What is the target breach rate?
Mức | Ý nghĩa
<5% | Good — reliable operation
5-10% | Accepted — needs improvement
>10% | Poor — unreliable commitment
Note: Don't ask for 0% — some customers are late for legitimate reasons (waiting for customers to provide information). Focus on decreasing, not chasing absolute numbers.
How to improve breach rate
1. Set true SLA
SLA is too strict compared to resources → breach is high by default.
Set realistic SLAs, gradually increasing as operations get better.
2. Warning before violation
Warning system when the ticket is about to expire - handle it before it's late.
Don't let tickets "die" in your inbox where no one can see them (see Multi-channel integration).
3. Right person for the right job
Tickets are difficult to assign to skilled people (see Ticket assignment).
Distribute volume evenly among employees.
4. Analyze reasons for delay
Late because of overload? Why wait for guests? Because of the process?
Correctly handle the cause, not just "get employees to work faster".
5. Check periodically
Weekly breach rate report, see trends.
When Breach increases, act immediately, don't wait for the end of the month.
