Organizational charts outline the internal structure of a company. Illustrating a company this way shows the internal hierarchy and how each role relates to others in the same organization.
Choreography diagrams depict the details of complex collaboration between process participants. This allows for an analysis of how information is exchanged and how participants coordinate their actions. Choreography diagrams are part of the BPMN standard, but are not widely used. We recommend staying with BPMN process diagrams.
For more information on Choreography diagrams, see the OMG BPMN specification document.
Conversation diagrams focus on communications between process participants. They allow for the viewing of relationships at a glance. Conversation diagrams are part of the BPMN standard, but are not widely used. We recommend sticking to BPMN process diagrams when modeling process participant interactions.
For more information on Collaboration diagrams, see the OMG BPMN specification document.
Event-driven process chains
Event-driven process chains (EPC) are used to model business processes. EPCs capture and visualize processes, but are--unlike BPMN--not executable. EPCs generally focus on the lower levels of the process hierarchy (operational sequences of processes). While EPCs were popular in some European countries in the late 90s and early 2000s, they have now been eclipsed by BPMN, which is more appealing to both business users and technical experts. We don't recommend using EPCs.
For more information on EPCs, see this page.
UML use case diagrams
Use case diagrams are used to view what actions can be performed collaboratively between systems and users. They are a part of the UML (Unified Modeling Language) standard. The Signavio Support Team can activate UML use case diagrams for your Signavio Process Manager workspace on request.
For more information on UML use case diagrams, see this page.
UML class diagrams
Class diagrams show the properties, methods, and relationships of a system's classes. They are commonly used to describe object-oriented programing code. They are a part of the UML (Unified Modeling Language) standard. The Signavio Support Team can activate UML class diagrams for your Signavio Process Manager workspace on request.
