Organizations today face challenges concerning the rapid environmental changes. The ability to continuously align business and IT is an essential quality of a modern enterprise. DI, a startup company, faces not only the growth of the organization but also constant growth in its system landscape. The alignment of business and IT can enable the organization to respond with suitable solutions to increase its business processes.

The Bachelor thesis is divided into three main phases. The first phase is the business analysis of DI, which involves discovering its vision, acquiring knowledge of its mission, and observing the business strategy. The second phase deals with the enterprise architecture modeling, using the ArchiMate standard to represent DI’s motivation for change in the IT landscape and to represent the company’s core business process with supporting applications. The last phase assesses the alignment between business processes and IT through a set of metrics.

The paper presents a model-driven approach with the modeling language ArchiMate to describe all the necessary aspects of enterprise architecture (EA). The collected findings provide first insights into EA and its corresponding frameworks. As a result, it offers a tool strategy for aligning the business with IT and measuring the alignment to improve efficiency in its business process execution. Consequently, the suggested tool strategy helps DI identify and choose the most appropriate software application that corresponds to its business needs to increase its work efficiency, leading to cost-effectiveness. Moreover, the tool strategy helps DI to cope with challenges and complexities and provides a fundamental understanding to solve the alignment problem between business processes and supporting software applications.
