The Application of the Maturity Model SIMMI 4.0 in Selected Enterprises

The increasing digitalization of business and society leads to drastic changes within enterprises. Therefore, they are confronted with enormous challenges when dealing with digitalization topics. One of these challenges represents the complex field of Industry 4.0/the Industrial Internet (as part of the digitalization), especially the realistic classification of the company’s own IT infrastructure in terms of Industry 4.0 requirements. Addressing these issues with the maturity model SIMMI 4.0 (System Integration Maturity Model Industry 4.0), we provide a toolset for enterprises to assess their current IT system landscape. In this paper, we present the next step of the iterative development of our model—the application of SIMMI 4.0 in selected enterprises as proof of concept. Therefore, we used a questionnaire-based approach to apply our model. We present the results and conclusions from this application as well as several further steps in our long-term research project to improve and refine SIMMI 4.0.
