Multisourcing is described as the blending of services from multiple internal and external vendors. In the case of one of the worldwide leading financial service providers the implementation of the multisourcing concept at the numerous business entities has been challenging since the group follows a federal IT organization model. By applying action research a multisourcing maturity model has been developed as an IT governance instrument. It is inspired by established maturity models and adapts proven methodologies whilst targeting the specific requirements of multisourcing. Thereby the maturity model provides transparency across all business entities, enables continuous monitoring of the multisourcing implementation progress and allows the provisioning of best-practices to a corporate group. With this article the authors provide insights into a real-life example of developing and implementing a multisourcing strategy and suggest an IT governance instrument for a multinational enterprise.enIT-GovernanceIT-Sourcingconference paper
