**Observability, evaluation, and testing each answer a different question. None decides whether an external action reached its promised outcome. Each page states where the tool fits.**

| Comparison | Question |

| [Outcome verification against observability](/compare/verification-vs-observability) | Is outcome verification the same as observability? |
| [Outcome verification against LLM evaluation](/compare/verification-vs-evaluation) | Is outcome verification the same as LLM evaluation? |
