Both business and IT departments have their own strategies. The IT strategy should support the business. Since the business has growth targets, the IT systems should be ready for it. As the application portfolio is very complex, fast growth is only possible with the acceptance of higher risks. Currently, the understanding between business and IT should be strongly enhanced. There is currently a lack of transparency on the IT side and trust into IT on the business side, which is also due to historical reasons.

The bachelor thesis was elaborated in three steps. First, a literature research on the relevant topics was carried out (IT strategies of the client, architecture patterns, technology trends, integration concepts, KPIs). Subsequently, the metrics were defined based on selected IT strategies and principles. The validation was carried out on five selected IT systems. The values obtained were then inserted into a suitable report. Since the client is operating in the energy sector, an energy label serves as a report, it was created based on the research paper by Schilling et al. (2019).

As a result, the client receives five defined key performance indicators with the respective sub metrics. Through the validation on IT systems, potential improvements have already been identified, which are also included in the thesis. As a second deliverable, the different energy labels are submitted. The labels exist for applications, microservices as well as for entire business units. A proposal for a drill-down into the individual sub metrics was also created. By using the energy label, the IT department of the client is enabled to improve communication with the business departments, since a common level of understanding has been created.
