Process modeling is a fundamental part of every business analyst’s work. Processes can be visualized and analyzed on the basis of modeled workflows between different people and systems, including the documents used, the regulations to be observed and possible risks. Usually, these models are created by business analysts who interview subject matter experts, observe human activities, read through system manuals and procedure guides, then manually draw their understanding of the process. They represent a human interpretation of how the process should optimally proceed. However, process models do not show how the process actually works in reality and therefore provide little solid analytical basis for workflow improvements.
