Bizagi is the most user friendly BPM suite that supports BPMN 2.0 all the way from modeling to execution. Although BPMN has been described as hard to fully implement in real-life. Bizagi is a very good tool for researchers to take BPMN theory into practice. Through modeling, running and testing business processes researchers can implement existing process patterns and also discover new ones. Bizagi has high potential to fully support BPMN 2.0 functionality, its support team is highly engaged with users and takes initiative in involving the users through feedback and providing top-notch customer support.
I highly recommend Bizagi to business process students and researchers.
