The three data roles

Data Owner

The data owner is an executive or senior manager with business accountability for a data domain. They have budget authority, business accountability, and the organizational standing to enforce standards in their domain.

• Resolve data conflicts that data stewards can't resolve
• Ensure domain data is fit for purpose for business use cases
• Sign off on data sharing agreements involving their domain data

Data Custodian

The data custodian is typically an IT or engineering role. They manage the technical infrastructure that stores and processes data, databases, pipelines, storage systems. They implement the access controls defined by governance but don't set the policies.

Building a data ownership model in practice

Most organizations assign data ownership wrong. They either:

• Assign it to IT (wrong: IT owns infrastructure, not business data)
• Assign it to the CDO (wrong: the CDO can't own all data, they set governance standards)
• Leave it unassigned ("we'll figure it out later"), the most common mistake

The right approach: assign ownership at the domain level, mapped to the organizational structure.

Map domains to business owners: Each domain maps to the executive who has business accountability for it. There should be no ambiguity. If two executives claim ownership of the same domain, that's an escalation to the CDO and ultimately the CEO.

Define ownership accountability metrics: Data ownership isn't honorary. Owners are accountable for scores in their domain, which feed into their performance metrics. In organizations that do this well, is a on the executive scorecard.
