What it can do
- Test Context - What are you trying to improve? What change are you considering?
- Current State - Baseline conversion rate? Current traffic volume?
- Constraints - Technical complexity? Timeline? Tools available?
- Not just "let's see what happens"
- Specific prediction of outcome
- Based on reasoning or data
- Single variable per test
- Otherwise you don't know what worked
Safety and limitations
- Things that shouldn't get worse
- Stop test if significantly negative
