Purpose
Ensure experiments are well-defined, measurable, and aligned with user experience considerations before launch.
Pre-run Checklist
- •✅ Align with analytics on measurement feasibility and sample size.
- •✅ Confirm design assets and engineering bandwidth for variants.
- •✅ Review related research or previous experiments for context.
