We are formalizing validation for high-impact reports. What combination of source-to-output reconciliation, edge cases, peer review, business-owner approval, and recurring checks works well?

When many departments rely on the same output, who owns definition, technical implementation, access, distribution, and change approval?

We have several outputs that answer similar questions differently. How have teams created a trusted definition catalog and safely retired redundant processes?

What makes a small synthetic dataset representative enough to test joins, dates, status changes, missing values, and boundary conditions without using member information?

How do you attach context and lineage to exceptions so analysts can determine whether the issue is timing, mapping, source quality, or report logic?
