Tableau and PowerPivot - a subversive partnership?

From the Tableau perspective, why is PowerPivot a credible data source? Since PowerPivot is a 'user-oriented' tool rather than an IT-oriented tool, it is possible that its complexity and offering can be overlooked. PowerPivot fits well with Tableau, which is also aimed at the business user audience. This blog offers a preview of some of the topics that I will cover at the Tableau European Customer Conference 2011, which is being held in Amsterdam. The focus of the blog is to explore how PowerPivot and Tableau can work together for business users, rather than in competition.
