This white paper is based on research conducted by Alliance Best Practice (ABP) originally started in 2002 which is ongoing to this day. So far over 600 organisations have contributed to the research which is ongoing. (For a complete list of contributing organisations and research reviewers see Appendices). The ABP database of findings from the research currently contains over 200,000 entries from organisations in multiple sectors. In each case at least three key stakeholders were interviewed in detail, these stakeholders were;Strategic, Managerial, and Operational. The result is a definitive examination of the common success factors in strategic alliances. Evidence from the ABP database shows that by paying attention to and enhancing the these success factors organisations can significantly improve their alliance relationship success. In addition the identification of common success factors is crucial in building effective alliance scorecards.
