How often should a marketing team update its internal data dictionary?

A marketing team should review and update its internal data dictionary at least once per quarter. Regular maintenance ensures that newly created CRM fields, updated campaign tags, and altered picklist values are documented immediately. It is also important to audit the dictionary whenever major tech stack adjustments or workflow changes occur. Gathering feedback from non-technical users during reviews helps identify unclear definitions that require additional refinement. Keeping documentation updated guarantees that it remains a trustworthy daily reference for the entire organization.
