Business intelligence–and its predecessor concepts decision support, executive information systems, and so forth–have been circulating for several decades in business. However, I don’t think it’s ever fully worked. What we’ve done is to throw data (often in the form of difficult-to-navigate data warehouses) and software tools at business users, and said “Go at it.” That’s simply been too hard. We used a lot of terms like “ad hoc queries” and “drill down,” but it simply didn’t happen very often.
