A service level objective (SLO) is a precise, measurable goal that a support team sets for a given operational metric—for example, "resolve 90% of chat contacts within 60 seconds" or "maintain a first contact resolution (FCR) rate above 75% this quarter." SLOs are distinct from service level agreements (SLAs): an SLA is a contractual commitment to a customer or client, while an SLO is an internal target that guides operations and staffing.
Why it matters: SLOs create a shared, quantifiable definition of "good" that helps teams prioritize, staff correctly, and identify when performance is degrading before it breaches an SLA.
Best practices:
- Set SLOs based on historical data and customer expectations, not arbitrary benchmarks
- Review SLOs periodically—contact mix and channel expectations change
- Pair each SLO with an error budget (the acceptable margin of underperformance)
- Make SLOs visible to agents and team leads, not just management
A missed SLO is a leading indicator; an SLA breach is the consequence of ignoring it.
