The challenge
The reporting layer could not support the decision.
A previous migration had stalled with conflicting models, incomplete platform coverage, and client-visible accuracy problems. The legacy pipelines could not support the attribution windows or creative detail the business required.
The implementation
One governed workflow from source to output.
Maven rebuilt the warehouse and dbt architecture, introduced reusable business logic and tests, combined standard extraction with direct APIs, and added automated discrepancy monitoring while maintaining reporting continuity.
