Experts agree that to improve data quality, you must be able to measure data quality. But determining what and how to measure is often challenging. The purpose of this tutorial is to provide participants with a comprehensive and adaptable approach to data quality assessment.
  • The challenges of measuring data quality and how to address them.
  • DQ assessment in context: Understand the goals and measurement activities and deliverables associated with initial assessment, in-line measurement and control, and periodic reassessment of data. Review a template for capturing results of data analysis from these processes.
  • Defining DQ requirements: Learn how to define measurable characteristics of data and establish requirements for data quality. Review a template designed to solicit and document clear expectations related to specific dimensions of quality.
  • Using measurement for improvement: Share examples of measurements that contribute to the ongoing improvement of data quality.
