This article reports the findings of a literature review concerning the potential benefits of Enterprise Integration (EI) for organizations. The review reveals the current state of the scientific literature concerning the potential benefits of EI, classified using a conceptual model of the enterprise. We believe that the results provide a consolidated and comprehensive picture of such potential benefits, useful as a baseline for future research. Additionally, the review is expected to assist practitioners in establishing business cases for EI by means of scientifically grounded reasoning about how EI benefits can contribute to the achievement of certain business goals. Additionally, results could be employed to develop methods or models capable of measuring such benefits in financial terms.
