Insurance Data Mesh

The promise of the centralized data lake was unified access to all enterprise data. The reality in most insurance organizations has been a maintenance-intensive bottleneck that serves few domains well.

Data mesh offers a different organizing principle: treat data as a product owned by the domain that generates and understands it. The claims team owns and maintains the claims data product. The underwriting team owns underwriting data. Each domain is responsible for its data quality, documentation, and access standards.

The federated model scales better because the bottleneck of a central team managing all data curation disappears. Domain teams have the context to build data products that are genuinely useful to their consumers rather than generic extracts that require extensive downstream transformation.

The governance challenge is real: federated ownership without federated standards produces a different kind of fragmentation. The successful implementations pair domain ownership with shared infrastructure and common data quality standards.
