SLO — Service Level Objective
Definition: The internal reliability target a team commits to — for example, 99.9% successful checkouts. SLOs sit one level above SLAs and force tradeoff conversations before customers feel the pain.
Example
Setting an explicit SLO of 99.95% checkout success ended the debate about whether to fix the flaky payment retry.
When you'll hear it
SLO shows up most often in engineering planning, architecture reviews, and sprint retrospectives. When someone uses it, they're usually referring to service level objective — and they expect the room to already know what that means.
