Return on investment (ROI) analysis of business intelligence (BI) can be a useful technique for evaluating alternatives, but only if the process is rigorous and evaluates all of the true costs over the life cycle of the technology. The premise of this paper is that lifetime costs of BI are inordinately high in best-of-breed implementations, that ROI analysis often misses this reality as a result of industry biases, tired methodologies that are too hard to displace, and (component) vendor persuasion. A single architecture, from a single vendor, is a very real alternative, especially given the marked propensity for information technology managers to think in enterprise terms more than ever before.
