As a company digitizes processes in its digital transformation (DX) journey, it is important to understand changes before and after processes for assessing the success of the journey. This paper proposes a new holistic approach, Digital TwinCity. By combining software visualization and process mining, the approach enables you to have an understanding of the relationship between all of the parts of the twin processes (e.g, before and after processes). After describing a tool implementing the proposed approach, we introduce its first application in a company.
