A data governance operating model for external data
As external data use scales, ad-hoc sourcing becomes a risk. A governance operating model brings order. This guide covers how to govern external data in practice.
Why governance is needed for external data
When many teams source data independently, duplication, compliance gaps and untracked licences multiply. A governance operating model defines who can do what, and how, so sourcing stays accountable at scale.
Core elements
- Roles: owners, stewards and approvers.
- Policy: rules for sourcing, privacy and licensing.
- Intake: a defined process for requesting and approving data.
- Catalogue: a record of what is held, with provenance and licence.
The intake process
A clear intake process, requirement, approval, sourcing, onboarding, prevents shadow data and ensures compliance checks happen before acquisition, not after.
Stewardship and accountability
Data stewards maintain quality, provenance and licence compliance for the datasets they own. Clear accountability is what makes governance real rather than a document.
Scaling without bureaucracy
Good governance is proportionate: light for low-risk data, stricter for sensitive or regulated data. The aim is to enable safe sourcing, not to block it.
In a managed model
A managed partner can operate much of this on the buyer behalf, providing a single intake, documented provenance and licence tracking, and a catalogue-ready record.
The intake process that prevents shadow data
The heart of a workable operating model is a clear intake process: a defined route to request data, with requirement definition, compliance and licensing checks, approval, sourcing and onboarding. When intake is easy and quick, teams use it; when it is bureaucratic, they go around it and create shadow data, untracked, unlicensed and ungoverned. Designing intake to be fast for low-risk requests and stricter for sensitive ones is what makes governance real rather than theatre.
Roles, catalogue and proportionality
Assign clear roles, owners, stewards and approvers, and maintain a catalogue that records what is held, with provenance and licence. Crucially, make governance proportionate: light-touch for low-risk public data, stricter for personal or regulated data. The aim is to enable safe sourcing at scale, not to block it; over-heavy process simply drives demand underground.
