Managing data quality is among the most vexing of information management issues. Most organizations have persistent and long-standing data quality problems—troubles that grow and propagate with the challenges of data redundancy, purchased applications and databases, legacy databases, multiple data providers and consumers, missing documentation, and uncertainty in defining data quality.

Stepping up to data quality improvement isn’t easy. It demands an understanding of quality management principles and practices, and the ability to apply those practices to a complex and continuously changing data resource. Whether your goal is a broad enterprise-wide data quality program or a highly targeted data quality project, you must begin by understanding the practices and processes of data quality assessment and improvement. This course is designed specifically to provide that foundational knowledge.

There are no prerequisites for this course.
