This document summarizes the key milestones in the development of BPMN 2.0 from 2007 to 2010. It outlines the new capabilities in BPMN 2.0, including a formalized metamodel, refined execution semantics, and new elements. It describes the business value of BPMN 2.0 in simplifying end-user processes and enabling portability. It also outlines the different conformance classes for tools supporting process modeling, execution, BPEL execution, and choreography. Finally, it discusses challenges in testing compliance and possible improvements to the conformance framework.

4. Business Value
End-user Simplification
Shorter learning curve as it is an extension of BPMN 1.x
Skills and investment protection
Unified notation for business processes and business interactions
Enables seamless “design-to-implement”
Vendor Productivity
Portability of process definitions enabled
Extendable language for future innovations
Investment protection

5. Conformance Classes
• For tool vendors whose tools support modeling of
orchestration processes and reasoning and not
necessarily process execution
Process Modeling
• For tool vendors whose tools support deployment of
business process models into execution
environments
Process Execution
• As per process execution, but for BPEL
environments, aligned with the process execution
standard
BPEL Process Execution
• For tool vendors whose tools support modeling of
choreographiesChoreography

7. Adoption Challenges
© SAP 2010, Template / Page 6
How to test compliance
with BPMN 2.0
Can optional elements (or)
attributes be ignored How to add additional
compliance points

8. Possible Improvements
Validate mandatory and optional elements and attributes
Clarify whether
An element (or attribute) is optional and does not have to be supported by
conforming implementations or
The value of the element (or attribute) is optional
Derive all static validation rules mandated by the specification
Introduce BPMN Profiles to simplify BPMN conformance points
Introduce conformance tests
