What Is Data Quality?

Data quality is a measure of the overall accuracy and completeness of data used in business operations. It includes factors like accuracy (correctness), consistency (similarity), timeliness (freshness), completeness (completeness), and relevancy (applicability). The goal of data quality management is to ensure that all data being used by an organization meets these criteria. This means cleaning up existing data sets, monitoring new incoming data sources, and ensuring that all systems are updated with accurate information.

Why Does Data Quality Matter?

Data quality matters because it’s the foundation for making informed decisions. Without accurate information, businesses can’t accurately assess their performance or identify areas where they need to improve. Additionally, poor-quality data can lead to inaccurate reporting which can hurt your reputation with customers or vendors. Finally, bad-quality data can be costly if you have to invest time and resources into recovering from mistakes caused by unreliable information.
