The Data Documentation Maturity Curve

Data documentation is crucial for managing growing data complexities within organizations, akin to how libraries evolved from simple systems to structured cataloging like the Dewey Decimal System. As data volumes and complexities increase, effective documentation ensures usability, reliability, and governance, enhancing collaboration, improving data quality, facilitating decision-making, and strengthening governance. The Data Documentation Maturity Curve, divided into Crawl, Walk, and Run stages, outlines a framework for organizations to assess and plan their documentation practices as they grow, recommending tools like Excel for initial stages, dbt Docs for intermediate complexity, and more comprehensive data catalogs like Select Star for advanced stages. These tools help manage metadata, streamline data discovery, provide data lineage, encourage collaboration, and maintain data quality, ensuring that organizations can adapt their documentation practices to support scalable and efficient data management.
