So, your company has a data warehouse? It was most likely implemented based on a specific business case addressing a specific business improvement opportunity. Everybody has to start somewhere. What makes an enterprise data warehouse extremely valuable to your business is when your users start gaining new and actionable insight (information/knowledge/wisdom) not previously available. So why don't we know what the insight would be beforehand? Why is it so difficult to predict and quantify benefits? More importantly, what can the business do to get smarter in this area?

Teradata has explored these questions. The result is a method of visual modeling to support understanding and planning as described in this white paper.
