Slide 2: About Today’s Speaker:
Robert Shapiro
WfMC Chair: Conformance and XPDL Vice Chair: Technical Committee Manager: ProcessAnalytica LLC Senior Vice President, Global 360 Robert Shapiro created the first open-architecture object-oriented graphical modeling toolkit for process modeling. It was the platform for Design IDEF in support of SADT (Structured Analysis and Design Technique) and used to build the first version of CPN (Colored Petri Net) modeling and simulation technology. Robert Shapiro is founder and manager of Process Analytica. He is Senior Vice President: Research, for Global 360. He founded Cape Visions (acquired in 2005) where he directed the development of Analytics and Simulation software used by FileNet/IBM, Fujitsu, PegaSystems and Global 360 Business Process Management products Prior to founding Cape Visions, as founder and CEO of Meta Software Corporation, he directed the implementation of a unique suite of graphical modeling and optimization tools for enterprise-wide business process improvement. Products based on these tools are used by Bank America, Wells Fargo, JPMChase and other major banks to optimize their check processing and Lock Box operations. As a participant in the Workflow Management Coalition and chair of the working groups on conformance and process definition interchange, he plays a critical role in the development of international standards for workflow and business process management. He has been instrumental in the creation and evolution of XPDL and BPMN. He was awarded the Workflow Management Coalition's Excellence Award at the AIIM 2000 Show in New York for his work completing the specifications for workflow process definition interchange. In 2005 he was awarded the Marvin L Manheim Award for outstanding contributions in the field of workflow.

Slide 6: When will BPMN2.0 be Finalized?
• As can be seen from the Open Issues list, there is much work to be done before the FTF can complete it’s work. • It is likely that some significant issues will have to be deferred to a subsequent revision. • Some simplifications are in progress.
– Collaboration and Conversation diagrams are being combined. – Work on SOAML may lead to some minor changes in the BPMN2.0 spec, but actual integration work will not be part of the current FTF.

Slide 8: Why Do We Need Sub-classes
• There are more than 100 graphical elements in BMPN 2.0. • Most BPMN modeling tool vendors will not support all of these symbols with their required attributes. • If vendors make arbitrary choices about which elements to support, models will not be portable between Tools.

Slide 9: Conformance Sub-Classes
• Spreadsheet of Visual elements indicating subclass members.
– BPMN Users Group | Google Groups
• SIMPLE Persona and example.
– Only eight elements.
• DESCRIPTIVE Persona and example.
– Contains SIMPLE. 21 Elements
• DODAF Persona.
– Contains DESCRIPTIVE. 50 elements of the 100 in the Complete Specification.

Slide 11: SIMPLE Persona
• A common situation for use of the SIMPLE class is process capture.
– A business analyst is sitting in a room with a group of process owners. – The session is attempting to map out a currently deployed set of processes that have never been suitably documented. – Technology for such a session may range from a low-tech whiteboard to a laptop and projector. – A process map is drawn by the business analyst as the process owners describe their operations step by step.

Slide 21: Every Vendor can support SIMPLE
• UI that allows the user to designate his or her persona • This would select a pallet of shapes appropriate. • In the process capture persona only eight symbols.
21
Slide 22: DESCRIPTIVE Persona
• A common situation for use of the descriptive class is fleshing out the details omitted in a process capture session.
– Using elements familiar from traditional flowcharting, the business modeler
• extends the routing logic to include the more critical exceptions (such as time-outs) and special cases, • adds information about resource or role requirements for performing activities, • adds some basic information about data flow • and provides an overview of communications between participants/
processes pertaining to the start and end of processes.

Slide 25: DODAF Enterprise Architecture based on Design Primitives and Patterns Guidelines for the Design of Business Process Models (DoDAF OV-6c) using BPMN
25
Slide 26: Roadblocks
• Enterprise Architecture (EA) is a key enabler of enterprise business process integration. • While Architecture Frameworks such as DoDAF exist to guide the development of consistent architecture artifacts, significant roadblocks still exist for effective architecture development, adoption, integration, and federation.
26
Slide 27: Lack of Uniform Representation
• Many of these roadblocks result from the lack of uniform representation for the same semantic content. • Architects use different methodologies to develop models • These models are represented using different modeling languages and created using different modeling tools.
27
Slide 28: Different Modeling Styles
• Even within a single methodology there may exist a variety of different modeling styles, techniques, and practices for similar content. • Moreover, enterprise architecture is necessarily created by different organizations and disciplines. • These in turn employ different terminologies that lead to different perceived business processes.
28
Slide 29: Need Standard Formats for Diagrams
• Standard formats for diagrams • Standard data formats for the exchange of these diagrams • Standard formats for data that moves within and between the architectures that diagrams represent.
29
Slide 30: DODAF Approach
• The proposed solution is a set of architectural primitives (the DODAF sub-class) and corresponding design patterns. • These primitives and patterns provide a core set of ‘building block’ modeling elements founded in the welldefined semantics of the DoDAF Meta Model (DM2). • These building blocks are accompanied by a recommended set of modeling techniques aimed at covering the different views on an Enterprise Architecture.

Slide 31: DODAF BPMN PRIMITIVES

Slide 32: Design Patterns in Context

Slide 33: DODAF SubClass in BPMN Spec
• The Primitives/Lexicon Project has two core deliverables:
– A Core Ontology of Architectural Primitives (PrOnto) providing the basic vocabulary / lexicon of model elements – Well-documented guidelines for modeling with Primitives (PriMo) delivering a comprehensive methodology for consistent model development. – Next Release will include approximately 50 primitives. – The primitives in the release define the DODAF subclass for the revised BPMN 2.0 specification.
33
Slide 34: Diagram Interchange
Tool A
Serialized BPMN Diagram
Tool B
Schema is needed to clarify if the document is written correctly or not.
XML Schema (XSD)
?
But BPMN 2.0 specification has no XSD schema included!
It is essential that the Finalization Task Force product a revised specification that includes a complete XSD for BPMN diagrams!
Slide 35: Redundancy Issues
• Discussion of early proposal for BPMNDI.
– At WfMC Maidenhead conference an early proposal for an xsd for DI (submitted by Bruce Silver) led to a discussion about redundancy between the semantic schema and the DI schema. – Subsequent discussion in the OMG BPMN 2.0 FTF led to common agreement on elimination of redundancy. – Further work by Silver and Scott Schanel led to a new proposal eliminating redundancy.

Slide 37: Deriving an XSD from the Metamodel • Work continues on basing the BPMN DI on the work of the OMG Diagram Interchange group.
– Maged Elaasar continues work on a metamodel and automatic generation of a BPMN DI schema. – Elaasar and Denis Gagne are now trying a bottomup approach building an XSD by hand that is closely alligned with the metamodel. The first version has been posted on the FTF wiki. – Incorporating some ideas from the Silver/Schanel proposal, the Elaasar/Gagne XSD appears to be quite simple. It is being tested against a range of examples. – There remain many details to be discussed.

Slide 41: Recent Work on XPDL 2.2 Schema
• .Scope: – The XPDL 2.2 schema effort is focused on only covering the Process Modeling Conformance class of the BPMN 2.0 specification. • Thus the XPDL 2.2 schema will offer a serialization and interchange transport for BPMN 2.0 Process Diagrams, Collaboration Diagrams and Conversation Diagrams including their layouts.
• Goal:
– The XPDL 2.2 schema is backward compatible with the XPDL 2.0 and XPDL 2.1 schemas. This backward compatibility also extends to XPDL 2.1 schema’s capability to serialize BPMN 1.2 drawings.
• Availability:
– Available as of December 2009. Version bpmnxpdl_39.xsd. – BPMN Users Group | Google Groups

Slide 44: XPDL Time Line
2010 Jan Feb Mar Apr May June July Aug Sep Aug
Feb 8: Documents available for review by WfMC members
March 8: Documents available for public review
April: Vote to approve or reject XPDL 2.2 release.
Slide 45: Predictions for 2010
• Many tool vendors will release versions of BPMN 2.0 modelers before the OMG FTF completes the specification.
– There will be several high quality modelers that are entirely web-based.
• Web-based facilities for converting XPDL and BPMN models will be available:
– Support for conversion between different versions and tools; also between XPDL and BPMN serializations.
• See http://www.businessprocessincubator.com/
• Work will proceed on the standardization of simulation scenarios for BPMN.
45
Slide 46: What You Can Do
• If you care about:
– the ease of use of BPMN for a wide audience, including process capture and high level modeling, not just modeling for execution. – the ability to move process models from tool to tool and/or vendor to vendor.
• Encourage the OMG BPMN Finalization Task Force to:
– Include Process Modeling conformance subsets in the specification – Create an XSD that is easy to work with and specifically designed to support the complete serialization of BPMN2.0 models, including all graphical details.
