Abstract
This short paper describes the IT Organization Modeling and Assessment Tool (ITOMAT) and how it can be used for IT governance decision making support. ITOMAT consists of an enterprise architecture metamodel that describes IT organizations. ITOMAT further contains a Bayesian network for making predictions on how changes to IT organization models will affect the IT governance performance as perceived by business stakeholders. In order to make such predictions accurately, the network learns from data on previous experience. Case studies at 35 companies have been utilized for calibration of the network.KeywordsIT governanceIT organizationEnterprise Architecturemodelingmetamodel
