Semantic layer
A semantic layer is the single place where metric definitions are implemented, so every dashboard and report derives from one implementation instead of restating it.
It is the technical answer to the definitional problem. Without one, "qualified pipeline" is implemented separately in the CRM report, the BI tool and the board deck, and those three implementations drift the moment any of them is edited. With one, changing the definition changes every consumer at once.
The layer is only as good as the governance around it. A semantic layer that anyone can add a metric to becomes a second pile of duplicate definitions with better tooling. Ownership and review are what make it a source of truth rather than a nicer place to store the same disagreement.
Where it breaks
A metric is defined in the semantic layer and then reimplemented in a dashboard because the layer’s version was inconvenient.

Field notes on this
- You just inherited RevOps. Start with a charter.
Being told to "own revenue operations" is not a mandate. Until authority is written down, every decision you make is reversible by whoever objects loudest.
- Why four teams report four different revenue numbers
A reconciliation problem may be definitional, technical, or both. Test the metric contract before buying another data platform.
