How to use it
Suggested steps
- Set the smallest improvement that would change your decision.
- Require coverage of important task types.
- Continue testing when the result is too uncertain to call.
| Check | What to look for |
|---|---|
| Evidence supports a clear decision | Stop according to the rule |
| Evidence is still too weak | Continue or withhold a decision |
Keep in mind Early stopping requires valid decision rules. Do not stop simply because the first results look good.
