Business intelligence is clearly in transition. Gartner has thrown its weight behind the idea of BI 2.0, although this recent entry into the 2.0 crowd is more about what's wrong with today's BI (e.g., incompatibility among vendors) than it is about what will come next.
Broadly speaking, what's coming next seems to be a shift towards operational BI, which integrates data from strategic, tactical and operational systems to deliver decision support to front-line managers who have to do things like make sure trucks arrive on time. (The "old" BI has been more focused on determining, months in advance, which products should be in those trucks.) In factories, the ability to integrate real-time data into BI so that managers can keep up-to-the-minute track of inventory is seen as a primary example of how the new BI can add value.
Another trend, to return to the 2.0 theme, revolves around making BI more useful to work groups. Several vendors are talking about integrating IM capabilities into their existing BI platforms.
All in all, there's no doubt that traditional BI is under attack, and price is playing a factor. New, low-cost or open source solutions for BPM (a close cousin to BI, if not a sibling) are surely going to have an effect on the evolving BI landscape.
