Episode 50 — 5.1 Build Governance Foundations: Documentation, Metadata, Lineage, Source of Truth
This episode introduces governance foundations as the mechanisms that keep data work consistent, auditable, and safe, which DA0-002 tests through scenarios involving conflicting numbers, unclear ownership, and uncontrolled changes. You will define documentation as the record of what data means and how it is used, metadata as descriptive information that enables discovery and correct interpretation, and lineage as the traceable path from source to transformation to report. You will also explain “source of truth” as a governance decision that prevents multiple teams from computing the same metric differently and then arguing about which is correct. The exam expects you to recognize that governance is not paperwork; it is the structure that makes analysis reproducible and reporting trustworthy. The objective is to understand the minimal governance elements that prevent the most common failures in multi-team data environments.
In the second paragraph, you will apply governance foundations to scenarios like reconciling revenue metrics across departments, tracking why a dashboard number changed after a pipeline update, and ensuring stakeholders interpret a KPI consistently month to month. You will practice identifying what governance artifact is missing when confusion occurs, such as a definition, an owner, a lineage record, or an approved refresh schedule. Troubleshooting considerations include preventing documentation drift by tying updates to change events, establishing ownership so someone can approve changes and respond to issues, and using simple change logs to connect metric shifts to specific updates. You will also learn how to communicate governance decisions clearly so stakeholders understand what is authoritative, what is experimental, and why consistency matters for decision-making.
