What's included

What gets programmed

• Cross-domain consistency logic that spans multiple forms or visits, beyond what point-and-click edit checks can express
• Derived and calculated-value checks, confirming computed fields resolve correctly against source data
• Pattern-detection logic across visits — trends, duplicate entries, and outliers that single-field checks won't catch
• Checks written by the same statistical programming team responsible for downstream SDTM/ADaM work, keeping logic consistent end to end
• Each check documented and traced back to its source rule in the Data Validation Plan before UAT
