By pursuing design science research (DSR) as the research orientation and utilizing expert interviews, action research and case studies as individual research methods, the authors propose a multisourcing maturity model as an IT governance mechanism. This article contributes in four areas: first, it derives requirements for IT governance mechanisms intended to support the implementation of multisourcing in business groups; second, it identifies the research gap by analyzing current concepts; third, it develops a maturity model; and fourth, it demonstrates the ap­plication of the model with two real-life case examples of leading financial services providers. Moreover, the maturity model provides practical guidance for coping with the challenges of implementing multisourcing by identifying the required capabilities, illustrates a desired evolution path to effectively and efficiently utilize multisourcing, and can be employed for steering multisourcing in business groups.enCCIIMIT-GovernanceIT-Sourcingjournal article
