SLA — Service Level Agreement
In plain English
A Service Level Agreement is a formal agreement that defines expected service levels, responsibilities, and performance standards.
An SLA is a promise about service.
It sets expectations for things like response time, availability, and quality — and what happens if those expectations aren’t met.
It answers the question: “What was agreed, exactly?”
What they actually mean
SLAs exist so everyone can point to the same document when things go wrong.
They rarely describe good service.
They describe the minimum acceptable one.
If someone starts quoting the SLA in a meeting, something has already failed.
Example
“According to the SLA, the response time is 24 hours — even though the customer expected a reply much sooner.”
Does it actually matter?
✅ Yes — contractually.
An SLA protects expectations, not satisfaction.
⚠️ Meeting the SLA doesn’t mean customers are happy.
❌ Missing it means someone is definitely unhappy.
