The maximum amount of time a system is allowed to fail without consequences, used to balance reliability with innovation velocity.
An error budget is a Site Reliability Engineering (SRE) concept that defines the maximum amount of time a system can fail without violating its Service Level Agreement (SLA). If your SLA says "99.9% uptime," your error budget is 43 minutes per month.
Marketers often push for "faster features," while devs push for "stability." The error budget gives both sides a shared, data-driven rule for when to push and when to pause.
