Using Data Lineage to Improve Data Quality with Piotr Czarnas

Ensuring data quality is paramount for modern enterprises as they navigate complex data environments across multiple cloud platforms. Piotr Czarnas, founder of DQOps, emphasizes that data quality issues often arise from challenges in data discovery and the reliance on outdated information, leading to ineffective business decisions. He suggests enhancing data discovery and using data lineage to track data flows and transformations across platforms, which aids in pinpointing and resolving quality issues. Czarnas provides a five-step strategy for improving data quality, including engaging data stakeholders, creating a central data quality repository, prioritizing critical data elements, and balancing automation with manual checks. Measuring data quality involves both objective metrics and subjective user feedback to ensure alignment with technical standards and user expectations. The future of data quality lies in integrating data catalogs with quality tools for better governance, involving business users in defining quality standards, and dedicating resources to maintaining data integrity. These approaches help organizations achieve reliable analytics and informed decision-making, crucial in a data-driven business landscape.
