That largely depends on the culture of the company. I've been at places that used BI to make decisions, and other places that just used it to nitpick over events from years ago. BI, like every other tool doesn't exist in a vacuum. It has to be present in an environment that has peopeople that know how to help themselves use the self-service attributes (i.e not Boomers), it also has to occur in a culture where KPIs and metrics are understood, and used in day-to-day discussions of the business, there should also be a training component to deploying your BI solution too. Without these aspects being present, your BI solution will devolve into either a sales prop with pretty colors, or it will become a web version of Excel.
