The document discusses managing a heterogeneous business intelligence (BI) landscape. It recommends segmenting the BI landscape based on the types of tools, users, and questions. Enterprise reporting tools should be used for high-quality presentation reporting, department tools for intermediate business questions, and specialized tools for data mining and analytics. Companies should develop a strategic plan to transition their BI landscape, focusing on phased implementations of best-in-class solutions for each segment. The transformation will require changes to technology, roles, and processes, and the plan should aim to deliver value and earn a return on investment.
