When Data Moves, Risk Moves with It: The Hidden Challenges of Warehousing Data

Summary

The episode explores how moving data into modern warehouses and lakes introduces hidden risks that go beyond technical challenges, emphasizing governance, data quality, and transformation controls. It highlights that inconsistencies in source systems, ambiguous definitions, and poorly documented transformation logic can lead to misleading analytics and flawed decision‑making. Legacy systems and rapid deployment pressures further exacerbate these issues, creating ownership gaps and security concerns. Internal auditors are urged to engage early, ask targeted questions about accountability, definitions, quality checks, and governance, and develop the skill set to assess data architecture without becoming engineers.
