Margy Ross and Bob Becker founded DecisionWorks Consulting in 1994, along with Nancy Rinn. For over 30 years, we’ve helped organizations leverage the information that’s collected by their operational systems to make better business decisions.

We pioneered this industry; our focus has been steadfast! We co-authored the best-selling Kimball Toolkit books on dimensional modeling and DW/BI methodology with Ralph Kimball. We’ve taught our best practices to tens of thousands of students, including over a decade via Kimball University. And we’ve consulted with hundreds of clients. That’s why we are the industry leaders in DW/BI methodology, design and education, especially when it comes to dimensional modeling. Although many competitors are larger, none were more experienced or relentlessly practical.

In 2003, DecisionWorks Consulting began doing business as The Kimball Group with Ralph and Julie Kimball, Joy Mundy, and the late Warren Thornthwaite. While the Kimball Group ceased operations at the end of 2015, the legacy lives on. Margy and Bob continue to offer the same vendor-independent DW/BI consulting and education services. You can still tap into their decades of experience!
