4. Workflow / BPM Reference Model

5. Design & Deploy Workflow / BPM Reference Model BPMN XPDL BPEL Standard Application Integration SOAP REST

6. BPMN: Business Process Modeling Notation Defines the way the process LOOKS Provides a dictionary of standard shapes with particular meanings Consistent use of shape/meaning benefits everyone: reduces the learning curve, training on shapes is useful for multiple products

7. XPDL: XML Process Definition Language The FILE FORMAT for a process definition Exchange process definitions between –Different BPM/Workflow Products –Process Modelling/ Simulation tools and BPM/Workflow Products –Supported by more than 70 commercial BPA/ BPM products and interoperability demonstrated; use of tools that support the standard ensures that you are not locked in to any particular vendor Full support for BPMN

8. BPEL: Business Process Execution Language Powerful programming language for Web service orchestration and XML manipulation Oriented toward building composite applications, not necessarily BPM Inflated expectations in media to be universal process language; now disillusioned No support for human activities –Look to BPEL4People effort to add this No sub-processes –Look to BPEL Subprocess effort to add this No on-the-fly process modifications

12. Consider BLOG Based Conversations Keith’s Blog Sandy’s Blog Bruce’s Blog conversation thread Individual blog posts

13. Implications Each blog is on a different server References are made between server Conversation threads knit servers together. No security problem (each person guards their own servers and their own posts.) Cost of system born by poster Style of post controlled by poster Scalability: extremely huge!

14. Distributed Federated Workflow / BPM Accounting Server Development Server Management Server Process Instances subprocess

15. Implications Process Fragements on different servers Wf-XML links knit servers together. No security problem (people start process fragments only on own server.) Cost of system born by people wanting and implementing a process fragment. Process definition controlled by owner Scalability: extremely huge!

16. Large Scale Federated Workflow Business Process Intelligence Warehouse BPMS Servers Worklist Users BPAF Wf-XML WorkCast

17. Business Process Analytics Format Business Process Intelligence Warehouse BPMS Servers BPAF Standardized Event Format –XML Syntax –Defined Attribute Semantics Process State Model Activity State Model Transfer –As a stream –On demand

18. Workcast Protocol BPMS Servers Worklist Users WorkCast Based on RSS & Atom Feed –Aggregates –Syndicates Extended with –Due Date –Priority –Activity State –Assignee –Etc.

19. Consistent Global ID is critical: OpenID Business Process Intelligence Warehouse BPMS Servers Worklist Users BPAF Wf-XML WorkCast OpenID

20. Delegation & Authentication: OAuth BPMS Servers Worklist Users Wf-XML OpenID Server1 access Server2 on user’s behalf OAuth protocol Secure API Authentication

21. Large Scale Federated Workflow Summary Multiple Servers, Federated Processes Collecting WorkItems (Workcast) Collecting History (BPAF) Consistent Identity (OpenID) Security (OAuth) Scalability: Incredibly Huge! BPAF Wf-XML WorkCast
