For a hot technology, business intelligence is mighty long in the tooth. BI has been around in one form or another, with one name or another, for decades. In all that time, it has never lived up to its potential, but business leaders aren't ready to give up on it. The critical question is, Can IT respond to the challenge this time?
IT had its chance to be the BI provider in the 1980s and 1990s and blew it by failing to address the BI challenge as anything more than a technical one. The last decade saw the business units try to take on BI without IT support, with only limited success.
The technical challenge of BI becomes less daunting all the time. Analytical software has improved tremendously, and there have been significant improvements in the hardware and software for managing large amounts of data -- which is good, since vast quantities of data are essential to business intelligence.
