Data Quality Assessment

What is a Data Quality Assessment?

A Data Quality Assessment is a distinct phase within the data quality life-cycle that is used to verify the source, quantity and impact of any data items that breach pre-defined data quality rules.

The Data Quality Assessment is a task typically executed by dedicated Data Quality Software. The software is used to first discover the data quality rules, define them against the source data, execute them across the data landscape and then finally provide interrogative reports on the results.

Closely linked with the Data Quality Assessment is the practice of defining and assessing Data Quality Dimensions. These are distinct rule groups or categories that can be assessed to provide comparative analysis of data quality levels across different tables, systems, business functions or even different organisations.

The Data Quality Assessment can be executed as a one-off process or repeatedly as part of an ongoing Data Quality assurance initiative.
