Atlas versioning for agencies inheriting messy accounts
Version labels that both brand and agency teams can cite during audits.
Agency transitions fail when audience atlases live in slide decks with ambiguous titles. Versioning should mimic lightweight API semantics: semantic labels, a changelog row, and a named approver from the brand side.
Start with a frozen snapshot whenever media ownership changes. Even if the underlying data is imperfect, the snapshot gives the incoming agency a defensible line in the sand.
Add a short “known gaps” section that lists exclusions the brand accepts temporarily. Transparency reduces thrash when the new agency proposes overlapping segments.
Close each version with a readiness note tied to the Predictive Net Response rubric. That linkage reminds everyone the atlas is an input to readiness, not a standalone trophy artifact.
