Business Intelligence is about much more than technology. In my opinion, a BI implementation is not succesfull simply because you installed and connected a dashboard to the companies datasources. A BI project can only be succesfull if the dashboard helps you to meet strategic business goals.
In this view, a BI project has as much to do with performance management and change management as with developing and designing a technological solution to support this process. A newsletter and blog I can recommend on these topics, is the one of Stacey Barr, an Australian performance management specialist and Jeffrey Gitomers Sales Caffeine that I like because it keeps me in touch with what kind of data sales might want to monitor their activities. Any tips on other newsletter of blog that are worthwhile are always welcome!
