The perceived importance of the topic IT governance increased in the last decade. Best practice reference models (like ITIL, COBIT, or CMMI) promise support for diverse challenges IT departments are confronted with. Therefore, the interest in best practice reference models (BPRM) grows and more and more companies apply BPRM to support their IT governance. But there is limited knowledge about how BPRM are applied and there is no structured method to support the application and lift the full potential of BPRM. Therefore, this paper proposes a structured method for the application of BPRM. Intention of this research is to reduce the inefficiencies caused by inconsistent and ad-hoc use of BPRM. The scientific adequacy as well as the practical applicability is critically discussed by using practical experiences out of an ongoing research project.
