11.8Common Mistakes
| Mistake | Problem | Fix |
|---|---|---|
| SLO set at 100% | No room for any failure; all development stops | Use 99.9% or 99.95% |
| Too many SLOs | Teams cannot prioritize | 3-5 per service maximum |
| SLO based on infrastructure metrics | Does not reflect user experience | Use request success rate, not CPU |
| No error budget policy | SLOs without consequences are just dashboards | Define actions at 50%, 25%, and 0% budget |
| Aspirational SLOs | Permanently exhausted budget demoralizes teams | Set SLOs based on measured baseline |
