The approach of Business Intelligence (BI) as a support function for management decisions is established in practice and theory. BI can not just be considered as a simple sequence of isolated single projects. Its coordination requires permanent efforts to keep the BI function and the business organization in alignment. In the context of the present empirical study, BI organizations have been analyzed for the diffusion of BI units and their distinct characteristics. Furthermore these organizations have been classified in different types of BI centers based on development and operational tasks. The results indicate a wide spread implementation of BI units in companies with a multifaceted range of duty. Thereby conclusions for the practical constitution of BI centers are deduced from the results.
