Session 4 Event processing in Workflows (BPM) Moderator Rainer von Ammon, University of Regensburg Panelists Name Affiliation Helge Hess IDS Scheer - EPC based tooling Daniel Jobst CITT / norisbank – instant credit Ling Liu GA Tech -- Brazil land zoning Francis Parr IBM Research - trade audit, energy process examples

3. AppServer Monitor / Analyze / Act Workflow Modeler Event Modeler Enterprise cockpit Event Store realize scenario process instances set parameters analyse history… Low Level Event Streams Adapters e.g. RFID, topics of Pub/Sub, … Build businesss level events Workflow Engine based on BPEL Rules Engine „special“ SQL resp. other languages IF … AND … FOLLOWED BY… WITHIN… ACTION Model ^= Scenario e.g. credit offers (completed) e.g. payments calculate pott, offer rates, profit… workflows The Technology Challenge and the Principle of BPM/BAM/CEP, e.g. for „Next Generation InstantCredit Systems“

4. Summary / Conclusions: Workflows can be either informal or automated –There is both BPN ( informal ) and BPEL ( executable ) Learnt that customers use “events” to describe their informal, non-automated business processes –Event Driven Process Chains used widely in Europe - events and activities –EDPC visualization tool for the business owner - iteration –Used to correlate gathered measurements of business behavior –Discovery and monitoring of ASIS processes to help TOBE changes or automation –Looking for bottlenecks etc … => ARIS EPC modelling tool and performance management tool - IDS Scheer Executable automated workflow systems e.g. BPEL – mainly invocation coupled –Problem to bridge the gap – event process descriptions – to invocation based SOA –Multiple steps in process to convert some EPC to BPEL – deployed to workflow –generated BAM monitoring capabilities – using events – simple stream –Use of events makes planned monitoring less disruptive, better => Case study (1) norisbank automated BAM using both BPEL and EPC models - compare (2) next generation instant credit system – event stream based monitoring Workflow as a transition network – associated with a project plan – informal WF –Event information on temperature, soil added to regional models  setting zoning assignments to different crops in a Region in Brazil Adding event capabilities to automated Workflow: –Can address by augmenting Workflow systems with event based triggering, request, state publish –Extend from workflow systems out to sensors – monitors as part of Control solution => Examples audit controls in stock trading with EDA triggers and requests; energy monitor In the past workflow initiated by explicit ( open –new account ) requests –Event driven workflow supports “implicit” triggers – potential fraud instance – not a requester

5. Summary Different uses of Event capabilities: –Modelling – getting user descriptions of current processes –Organizing gathered measurements on behavior of currently working business processes –Developing next cycle automated workflows –Developing next cycle BAM using events … Potentially based on –Common concepts models user by business owner, developer –Common underlying systems infrastructure - events, deployment –Coupled systems BPM description Executable automated workflows BAM and performance mangement Loop back
