What it shows

  • SLIs measure real user experience, while SLOs define target thresholds.
  • Error budgets quantify acceptable failure to balance velocity and safety.
  • Toil reduction caps repetitive manual operations at 50% of engineer time.

The takeaway

Reliability is not about zero failures; it is about managing failure within an explicit error budget.
