A company adopts a data mesh model. The marketing domain's customer engagement data is to be published as a reusable data product. Who should be accountable for its quality, documentation and service levels?
Show answer and explanation
Answer: C
In a data mesh, ownership moves to the business domain that understands the data best. The marketing domain team publishes its engagement data as a data product and is accountable for quality, documentation and service levels. Embedded data engineers help the team build and maintain the product. A central platform team provides shared tooling and governance guardrails, but it does not own domain content. Short engagements and ad hoc consumers cannot carry long-term accountability.
Why the other options are wrong
- A. The platform team supplies self-service infrastructure and standards for the mesh. It does not own the business meaning or quality of domain data, so it should not be accountable for marketing products.
- B. A temporary contractor lacks long-term accountability and institutional knowledge. Data products need durable ownership with service levels, so a short engagement cannot be the owner.
- D. Consumers who query a table most often are not necessarily accountable for it. Ownership is a responsibility assigned to the producing domain, not a function of how frequently the data is used.
