Workflow

- Profile key uniqueness and missing data before matching or aggregating.
- Calculate the result on a small sample and reconcile it manually.
- Run the full dataset, review exceptions, then export the evidence you need.

What can go wrong
Most incorrect results come from the wrong key, one-to-many joins, mixed data types, hidden whitespace or aggregating at the wrong grain. Treat these checks as part of the analysis, not optional cleanup.
