Our solution is compatible with the de-facto standard of business process modeling — BPMN 2.0 (Business Process Model and Notation). It can detect various modeling faults and poor design solutions, and highlight them on a model diagram, so users do not need to find which exactly element causes troubles. Highlighted weak spots are interactive — users may hover them and the detailed enough explanation what is wrong with this element is provided. It is accessible and easy-to-use for all non-technical users involved into the business process modeling activity.
