Letter from the Editorial Director

TDWI proudly presents volume 22 of What Works: Best Practices in Business Intelligence and Data Warehousing. This compendium of content provides an information resource for better understanding the tools, technologies, and methods that are central to this growing industry.


The goal of What Works is to provide a snapshot of the most innovative business intelligence and data warehousing implementations in the industry today. The case studies included in this volume demonstrate the power of BI for industries ranging from retail to education, insurance to transportation.


What Works also includes articles from leading experts in the services, software, and hardware vendor communities. These “lessons” feature perspectives about how to build successful BI environments—including such topics as data governance, getting more value out of enterprise data, and high-speed backup of the data warehouse.


Our Q&A section provides answers from these same experts to the questions they hear most often, complemented by insight from an independent consultant.


Volume 22 features two articles from TDWI’s director of research and services, Wayne Eckerson. In “Is Your BI Environment Protected?” he asks an important question: what is the biggest threat to your BI environment? In “The Real Value of BI Search,” he explains why current trends in BI search may be symptoms of a larger problem.


What Works includes excerpts from TDWI’s recent best practices reports: Deploying Dashboards and Scorecards by Wayne Eckerson and Master Data Management: Consensus-Driven Data Definitions for Cross-Application Consistency, TDWI’s latest report from Philip Russom.


This section features the winners from TDWI’s annual contest, which recognizes organizations for developing and implementing world-class business intelligence and data warehousing solutions.

We hope you enjoy this collection of case studies, best practices, and expert insight, and we look forward to your comments. If there is anything we can do to make this publication more valuable to you, please let us know. And please join me in thanking the companies who have shared their stories and successes, their technology insights, and the lessons they have learned.
