Managing Data Quality in a data warehouse is a never ending adventure. In this presentation we will be reviewing the process, levers, and technology changes that BCBSA has implemented to try and support the increasing demand for data. This case study follows the evolution of data quality over the past decade with BCBSA's National Data Warehouse (NDW). NDW is a warehouse consolidating data from the 36 companies and over 100 million members that make up Blue Cross and Blue Shield across the US. Questions that will be answered: What are the new processes being employed? What are the new technologies being implemented? What has stood the test of time?
