From Process and Enterprise Architecture to Digital Enterprise Twin in the Metaverse

The use of innovation potential for new business ideas requires knowledge of the existing initial situation, i.e. the existing business models and processes. Only then can changes or extensions be added quickly. In many companies, this step encounters a process and IT landscape that has often grown over decades and consists of heterogeneous hardware and software and lacks adequate documentation. If necessary, this landscape must be subsequently documented to the extent that the interfaces between old and new systems can be defined. Only in this way can the transformation succeed and be a prerequisite for a composable enterprise. Methods such as ARIS-EPC and BPMN are presented and demonstrated by using an example. The extension of process modelling leads to the description of the entire corporate context in an enterprise architecture. For this purpose, the ARIS house is presented as a framework concept and ways of automatically creating and maintaining an EA are shown. Technologies such as digital twins and the virtual worlds of the metaverse open up imaginative perspectives. Statements that are very specific or refer to specific systems are marked in italics. Readers who are more interested in an overview can skip these parts without losing the content guide. The following figure establishes the connection to the lifecycle in Fig. 1.9.
