What it is#
SLA Breach Rate is a performance metric measuring how often a service provider — a supplier, IT team or internal group — fails to meet the service levels agreed in the SLA. Each breach is a missed target (a late delivery, missed uptime, poor quality), and the rate reports the percentage of obligations not met over a period. It is the exact opposite of the SLA compliance rate.
The formula#
where breaches count the times performance fell below target and obligations count every chance there was to meet it.
Worked examples#
In a supply chain, 1,000 orders with 50 delivered late gives a breach rate of 50 / 1,000 = 5%. In an IT support desk, 2,000 tickets with 200 missing their resolution deadline gives 200 / 2,000 = 10%.
Why it matters, and reducing it#
The rate drives accountability, signals customer satisfaction, triggers contractual penalties or credits, and pinpoints weak areas. It falls with better forecasting, real-time monitoring and alerts, supplier collaboration, automated escalation, and realistic SLA reviews. Its mirror image is the compliance rate (100% minus the breach rate), and the common KPIs it is measured against are on-time delivery, fill rate and uptime.
