Data Governance Framework (2026): Practical Guide and Roles

What a data governance framework covers

Component	What it means
Principles and policy	A short statement of how data is treated, owned and protected
Roles	Data owners, data stewards, data custodians and a governance group
Data standards	Definitions, formats and quality rules for critical data
Data quality management	Measuring, reporting and fixing data issues
Metadata and catalogue	Where data lives, what it means and where it comes from
Access and security	Who can see and change what, in line with UK GDPR
Lifecycle and retention	How long data is kept and how it is disposed of
Issue and change management	How problems are raised, prioritised and resolved

The key roles

Data owner: a senior business leader accountable for a data domain, such as customer, product or finance.
Data steward: the person who maintains definitions and quality rules day to day.
Data custodian: the technical team that runs the systems where the data lives.
Governance group: a small forum that sets priorities and resolves disputes.

How to get started

Pick the data that matters most, usually customer, product, supplier and finance data.
Name an owner and a steward for each domain.
Agree definitions for the twenty or so terms that cause most arguments.
Measure quality on a few critical fields and publish the results.
Fix the causes of the worst issues, not just the records.
Expand once the first domains are working.

Data governance and AI

AI makes data governance more important, not less. Models are only as reliable as the data behind them, and regulators expect organisations to know what data their AI systems use, where it came from and how it is protected. Align data governance with your AI governance framework rather than running the two separately.

Common mistakes

Starting with a long policy document instead of a few owned data domains.
Treating governance as an IT project.
Measuring everything and fixing nothing.
A governance committee with no authority to make decisions.

Common questions

What is a data governance framework?

The roles, policies, standards and processes an organisation uses to manage data as an asset: who owns it, what good looks like and how issues are fixed.

What are the main roles in data governance?

Data owners, who are accountable for a data domain; data stewards, who maintain definitions and quality; and data custodians, who run the systems. A small governance group sets priorities.

What is the difference between data governance and data management?

Data governance sets the rules and accountabilities. Data management is the day to day work of collecting, storing, integrating and maintaining data within those rules.

How long does it take to set up data governance?

A focused start on a few critical data domains can be running within three months, with broader coverage built over the following year.

We help organisations set up data governance that is proportionate, owned by the business and linked to the decisions and systems that depend on it.
