1.1.Modeling

jBPM currently allows users to create and modify business processes using graphical flow charts.

1.2.Deployment

Guvnor can be used as a knowledge repository, for storing your processes, domain model, business rules, etc. Guvnor provides a web-based management console for inspecting, modifying and testing your knowledge. The Oryx Designer is integrated with the Guvnor console. Guvnor also supports collaboration between different users, scenario testing, packaging, etc。
