The important steps: 1. Redesign the business processes for SOA and BPM 2. Make a SOA, identify services, build WSDL-interfaces…3. Precise description of patterns of events

4. Detecting patterns in the event cloud

5. Abstraction of complex event pattern instances to higher level events

Forcast of ED-BPM for the next decades

Forecast of Prof. David Luckham:

  • we need skilled people at least up to 2050…
  • we are only at the end of the period of Simple CEP
slide8

The forecast of ED-BPM for the next decades

The warning of Roy Schulte (VP of Gartner) since 2006…

…we won‘t have enough skilled people who would be able to do all the jobs and projects

The statement of Prof. Mani Chandy (California Techical University) at the Gartner Event Processing Summit 2007…

…The work of IT during the next twenty years will be to complete the evolution of business processes from sequences of slow-moving, disjointed applications to more responsive end-to-end, event-based straight-through flows of action.

A proposal for a curriculum of a new Master course of study“Event-Driven Business Process Management”

Draft V0.1

The business modeller and the event modeller – different qualifications not in personal union

Description:

Curriculum together with required credits and examinations

Certificate:

Master of Science

Programme Duration:

Four Semesters (120 credits/cr)

Mastercourse-EDBPM-v01.doc(www.citt-online.com)

slide10

The business modeller and the event modeller – different qualifications not in personal union

Concept:

The course consists of the fields of study Business Process Management, Complex Event Processing, Business Activity Montoring included Business Intelligence and Data Warehousing, Computer Networks, Messaging as well as several application disciplines like Algorithmic Trading, Supply Chain Management in the retail domain, fraud detection in the banking and insurance domain etc.

All courses are completed with course-related tests and Credits (cr) according to European Credit Transfer System (ECTS) are awarded. All courses are given in English and are designed as distance learning/eLearning courses.

Previous Work

Several Proof of Concept (PoC) Implementations

  • PoC in the logistics domain in cooperation with Deutsche Post AG and Oracle

Event Driven Business Process Management taking the Example of Deutsche Post AG, An evaluation of the Approach of Oracle and the SOPERA Open Source SOA Framework(C. Emmersberger, F. Springer; September 07 – March 08)

  • PoC in the finance domain in cooperation with TeambankApplication for monitoring the credit application easyCredit of Team Bank and the evaluation of several CEP approaches(H.-M. Brands, D. Guschakowski; 2007)

EDBPM Background and Definition

Event-Driven Business Process Management (EDBPM) is a combination of two different disciplines:

  • Business Process Management (BPM): Deals with the management of business processes with the approach to increase the efficiency, flexibility and technology integration of the business.Business Processes describe the unique way of doing business. Today they are seen as the most valuable asset of a corporation.
  • Complex Event Processing (CEP): A concept that deals with handling multiple events within an event cloud to identify meaningful event patterns. It is an emerging technology for obtaining relevant situation knowledge from distributed systems in realtime (= event time + processing time) to monitor or react on emerging errors.

=>EDBPM could improve the business

Logistics Use Case for EDBPM

  • PoC investigates the feasibility of combining Oracles tools for BPEL, CEP and BAM with the latest Sopera Enterprise Service Bus (ESB)
  • Use case serves a PoC implementation for a solution combing the goals of service-oriented architecture (SOA) with the advantages of CEP
  • Use case contains a typical business process at Deutsche Post addressing “shipping”, “monitoring/investigation” and “claim”
  • Sopera services are orchestrated through Oracle’s BPEL engine and implement the process functionalities. They are capable to send events.
  • Oracle’s CEP Engine queries the events and sends results to the BAM application for displaying and alerting purpose

Example:

Simplified Illustration of Components and Interaction

Development:

  • Service development in SOPERA
  • Service orchestration in Oracle BPEL
  • Setup events, which should be sent from the Notification Receiver (event service). Settings are defined as SOPERA policies in XML
  • Development of CEP patterns in Oracle CEP with CQL
  • Design of reports for the BAM dashboard in Oracle BAM

External events (e.g. traffic)

Runtime:

  • Execution of a business process in the BPEL Engine
  • Notification Receiver deals as event service. Creates and sends business and technical events to a specified endpoint (BAM, CEP)
  • Complex Event Processing in Oracle CEP
  • Process reporting in Oracle BAM

Hurdle: Merging Event Information of Oracle and SOPERA

Hurdle:

  • Oracle BPEL Engine and SOPERA are running isolated from each other
  • The SOPERA Web service has no information about the process which has executed the service
  • CEP has no chance to connect events coming from Oracle BPEL with SOPERA Service events

Task:

  • Connect the independent events

Solution:

  • Enhancing the message payload with BPEL process information.
  • BPELContent includes the filed “ProcessID” as an unique identifier for an executed process
  • BPELContent is sent every time when a service is called during process execution. This mechanism closes the gap between Oracle and SOPERA

Intrusive generated events:

Service has to implement code for event generation

Disadvantage:

Existing code has to be changed (e.g. a bank would not allow to change existing code)

Business functionality and monitoring have to work independent. Service should provide only business functionality.

Advantage:

Information which is not part of the payload can be used

Non-intrusive generated events:

Information is extracted out of the payload and the service with adapters and sensors. The extracted information has to be merged to an event.

Disadvantage:

Only payload and public service information can be part of an event

Advantage:

Service Code has not to be changed

Service has not to deal with monitoring functionality

Aggregation and correlation to business level complex events

Several event types influence the business process:

  • Process events: happening during process execution and
    • Business events: providing business content, e. g. parcel allocated to truck
    • Technical events: providing technical content, e. g. service not available
  • External events: events occur outside the business process, but also influencing the process, e. g. weather, traffic

First link between BPM and CEP

Main concepts of both technologies in a general reference model for EDBPM

CONCLUSION

The Paper Provides:

Summary:

  • EDBPM is able to detect possible errors within a business process using CEP technology and alert responsible persons using BAM
  • Added business value compared to pure BPM solutions, but currently hard to implement

Perspective:

  • Automatic reaction on errors has to be implemented in future solutions, e.g. conditional decision and reaction logic
  • Additional use cases can be defined for various domains and first projects on the basis of such “Event Driven BPM” platforms start in 2008
  • Research projects for a faster set-up of EDBPM are currently under preparation

Detailed Information:

  • Further information about the PoC can be seen on www.citt-online.com in a video presentation hold on the 6th CEP/BAM expert meeting in Regensburg

Tasks for the future

Analyzing different domains and provide CEP patterns and

best practices for each domain

Current PhD thesis:

  • Domain Specific Reference Models for Complex Event Processing Patterns in the domain of Finance/Banking (F. Springer)
  • Domain Specific Reference Models for Complex Event Processing Patterns in the Automotive Domain (C. Emmersberger)
  • Domain Specific Reference Models for Complex Event Processing Patterns in the Retail Domain (T. Paulus)
