Survey & sampling design
Sampling frames, allocation, and instruments that survive being argued about.
Most survey error is baked in before anyone reaches the field. We settle it at design time: define the target population explicitly, choose a sampling scheme that matches the population structure, size the allocation against the precision actually required, then test the instrument until the questions stop being ambiguous.
