BPMN 2.0 is an international standard that comprises both a notation as well as an XML serialization format. This facilitates the interchange between modeling tools and process automation environments.
Signavio was the world's first vendor to offer a comprehensive realization of the BPMN 2.0 standard. Now, Signavio diagrams can directly be used in IT implementation environments.
Most Signavio customers have already switched to version 2.0 over the last months. All those customers who are still using BPMN 1.2 can still edit their diagrams using the Signavio Process Editor or can convert them to BPMN 2.0.
