Disagreement over numbers is usually a disagreement over definitions. AI assistants that query your data will multiply the problem unless definitions are fixed in one place.
Steps
- List the key metrics and agree one written definition each, with an owner.
- Implement them once in a shared layer that dashboards and AI tools both use.
- Version changes and record when and why a definition changed.
- Show the definition next to the number.
A natural-language data assistant is only as reliable as the definitions beneath it. Fix those first.
