I'm really resisting the urge to yell "INCOMING!!!!!!"

I've read statements from both Inmon and Kimball that their respective takes on datawarehousing (or whatever you want to call it) are a lot closer than most people think and most of the flamewars are the results of people not completely comprehending their approaches.

There are advantages and challenges with each method and as PaulB said, the success/failure of a given DWH has more to do with the skills of the architect than anything else.

I'd look at it as an opportunity to challenge your own ideas about building a DWH and learn why the company uses the approach they do. Conversely, there is also an opportunity to show where some of Kimball's ideas might benefit. Regardless of outcome, it isn't personal, it's just business.
