A Practical Data Governance Framework for Mid-Market Organisations

A mid-market data governance framework should make important data easier to trust, access appropriately and fix when it fails. It does not need a large data office, a catalogue of every asset or months of policy writing.

The minimum viable framework is one where every priority data product has an accountable owner, agreed rules, a usable access path and a recurring review. Technology can support those controls, but the framework begins with decisions and roles.

Start with governed outcomes, not the whole estate

Choose two or three outcomes where data failure has a visible commercial, operational or regulatory consequence. Examples include the monthly financial pack, customer reporting, a regulatory submission or an AI use case that retrieves personal information.

For each outcome, identify the smallest set of source data, transformations, models, reports and users that must be governed. This prevents the programme from becoming an inventory exercise before it has helped anyone make a decision.

The DAMA Data Management Body of Knowledge provides a broad, consensus-based view of data management disciplines. It is useful as a reference, but DAMA also describes it as a body of knowledge rather than a prescriptive standard. A mid-market framework should select the controls needed for its context instead of attempting to implement every possible practice at once.

The six parts of a workable framework

1. Scope and principles

Write a one-page charter that states:

• Why governance exists in your organisation.
• Which outcomes and data are in the first scope.
• The principles used to make decisions.
• Who sponsors the work.
• What is explicitly out of scope for now.

Useful principles are operational. Examples include:

• Business owners are accountable for meaning and acceptable use.
• Technical custodians are accountable for reliable implementation and operation.
• Access follows least privilege and a valid business purpose.
• Quality is assessed against intended use, not an abstract ideal.
• Material decisions and exceptions are recorded.
• Data is retained only as long as required by purpose and obligation.

Avoid statements such as "data is an asset" unless the next sentence explains what someone must do differently.

2. Roles and decision rights

Five roles are enough for the first scope. One person may hold more than one role in a smaller organisation, but accountability should remain explicit.

Create a short decision-rights register. For each recurring decision, state who proposes, who approves, who must be consulted, the response time and the escalation route. Start with definition changes, quality exceptions, access approvals, new uses and data-product retirement.

3. Data products and business definitions

Organise governance around usable data products rather than raw asset counts. A data product is a set of data assets packaged for a defined use, with an owner and service expectations.

For each priority product, record:

• Purpose and intended consumers.
• Accountable owner and operational steward.
• Authoritative sources and included assets.
• Critical business terms and measures.
• Refresh frequency and availability expectation.
• Quality rules and current status.
• Sensitivity, permitted use and access route.
• Known limitations.
• Review and retirement date.

Definitions deserve particular discipline. A term such as active customer, recognised revenue or service completion should state the rule, effective date, owner and affected products. If two valid definitions exist for different uses, document the distinction rather than forcing false consistency.

Microsoft Purview governance domains and data products can hold this context and make it searchable. A spreadsheet or lightweight register can support the first design. The tool choice should follow the scale, source coverage and operating need.

4. Quality and issue management

Data quality is fit for use, not perfection. Define rules only where failure changes a decision, creates rework, harms a customer or creates unacceptable risk.

A practical rule record includes:

• The field, measure or event being tested.
• The quality dimension, such as completeness, validity, timeliness or uniqueness.
• The threshold and reason for it.
• The test frequency.
• The owner of the source correction.
• The action when the threshold is missed.
• The time allowed to resolve or accept the issue.

Use an issue register for material failures. Record impact, affected products, root cause, owner, due date and resolution.

If Purview is part of the environment, Unified Catalog data quality can apply rules and report scores across assets, products and domains. The framework must still specify which scores matter and what action follows.

5. Access, acceptable use and lifecycle

Access control should answer more than "can this account open the file?"

For each priority product, define:

1. Who may request access.
2. The valid purposes for use.
3. Who approves and within what time.
4. What level of access is provided.
5. When access expires or is reviewed.
6. Whether export, onward sharing or AI use is restricted.
7. How access is removed.
8. How an exception is recorded.

Classify data according to its actual sensitivity and obligations. Keep the scheme small enough that staff can use it consistently.

Australian entities handling personal information should align controls with the OAIC's APP 11 guidance, including reasonable technical and organisational protection and appropriate destruction or de-identification when information is no longer required. In New Zealand, Privacy Principle 5 requires reasonable safeguards against loss, misuse and unauthorised disclosure. Specific legal obligations still need qualified advice for the organisation and sector.

Purview can support metadata permissions and, for supported scenarios, data-product access policies. Microsoft's roles and permissions guidance should be read alongside permissions in the underlying Azure, Fabric and source resources. Test the full access and revocation path rather than assuming a catalogue role controls every system.

6. Cadence and measures

Governance needs a small operating rhythm.

Weekly operational review

The steward and custodian review material quality failures, overdue access requests and changes affecting the priority products. They resolve routine items or send a clear decision to the owner.

Monthly owner review

Each owner reviews product health, unresolved issues, access exceptions, definition changes and upcoming source or report changes. This is an exception review, not a presentation of every metric.

Quarterly governance review

The sponsor and relevant owners decide priorities, accept or reject material risks, retire unused products and approve expansion into another domain or outcome.

Start with measures that show whether governance is working:

Do not use the number of catalogued assets as the headline measure. It shows platform activity, not whether important data is understood or controlled.

A 90-day implementation sequence

Days 1 to 30: decide

• Select the first two or three outcomes.
• Name the sponsor, owners, stewards and custodians.
• Approve the charter and decision rights.
• Identify priority data products and critical definitions.
• Record applicable privacy, security and sector obligations.
• Establish baseline pain, such as reconciliation time or issue backlog.

Days 31 to 60: build the controls

• Map the minimum data chain and authoritative sources.
• Document products, definitions and classifications.
• Define quality rules and issue handling.
• Design request, approval, review and revocation paths.
• Configure the required Microsoft environment, including Entra ID groups and source permissions.
• If using Purview, scan only the sources required for the first scope and curate the relevant domains and products.

Days 61 to 90: run the operating loop

• Process a real access request from start to finish.
• Trigger or simulate a quality failure and complete remediation.
• Test a definition change and impact assessment.
• Complete the first owner review.
• Measure adoption and service levels.
• Decide whether to improve the pattern, extend it or stop work that has not earned expansion.

When to add Microsoft Purview

Purview becomes more useful when metadata is distributed across several systems, lineage and discovery matter, multiple teams need governed products and manual registers no longer stay current. Its Data Map and Unified Catalog capabilities can make the framework operational across a larger estate.

As explained in Microsoft Purview is not your data governance strategy, the platform cannot provide missing owners or settle business decisions.

If scope, ownership, architecture or the first outcome is unclear, begin with a Data & AI Readiness Assessment. If the use case is ready, a defined Microsoft Fabric consulting and implementation engagement can establish the governed foundation inside your Microsoft environment.
