Portfolio Data Governance

How a multi-brand company can define ownership, quality, access, retention, and correction standards for portfolio data.

Published July 28, 2026Original material

Define data ownership

Every important dataset and report needs a clearly named owner.

Create common definitions

Shared terms reduce confusion across companies.

Control access by purpose

Access should follow a documented operating need.

Preserve correction history

Material changes should retain version and correction records.

Review retention

Data should not be kept without a business, legal, or security reason.

Methodology and limitations

This framework should be adapted to industry, regulation, consequence, and company stage.
