Today Information Technology (IT) can be found in every modern enterprise. As IT has
become one of the most crucial parts of an enterprise, it has made management aware of the significant
impact IT has on the success of the enterprise. This has led to a significant increase on IT investments. IT
governance aims at assuring that IT delivers more value from IT investments and enforcing IT’s role as a
business enabler.
This master thesis aims at assessing the IT organization at AB Storstockholms Lokaltrafik (SL) from an IT
governance perspective. The purpose of such assessment is to identify problem areas and suggest measures
for improvement. The IT governance framework COBIT (Control Objectives for Information and related
Technology) has guided the theory for IT governance throughout this study. A framework for the
assessment of the IT governance maturity at SL was developed based on the IT Organization Model
Assessment Tool (ITOMAT), a formalized method for assessing the IT governance maturity.
The IT governance maturity of SL obtained the score 2,68 out of 5,00. Considering the fact that SL started
with the process of introducing IT governance to the organization as recent as 3 years ago, the result
obtained is considered high. It indicates that significant progress has been achieved in their IT governance.
Nevertheless, the organization still has significant potential for improvement.
