IT GOVERNANCE DECISION SUPPORT USING THE IT ORGANIZATION MODELING AND ASSESMENT TOOL

Abstract

This paper describes the information technology (IT) organization modeling and assessment tool (ITOMAT) and how it can be used for IT governance decision making. The ITOMAT consists of an enterprise architecture metamodel that describes IT organizations. Further, ITOMAT 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. Thorough case studies at 20 different companies have been conducted in order to calibrate the network. Finally, the paper describes a case study where ITOMAT was used to analyze the future impact of two IT organization change scenarios in a medium-sized engineering company.IT governance, IT organization, enterprise architecture, modeling, metamodel
