2 2 Rainer v. Ammon Agenda The forecast of edBPM for the next decades edBPM – a combination of two disciplines: Business Process Management (BPM) and Complex Event Processing (CEP) A reference model for edBPM – how its components work together edBPM-enhancements of the NEXOF-Reference Architecture edBPM-enhancements of modeling and execution standards Domain-specific standards for Notification Event Architectures Standardising Event Processing Languages Domain-specific reference models for use cases and event patterns edBPM-based software solutions and products

3 3 Rainer v. Ammon The forecast of ED-BPM for the next decades The 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

4 4 Rainer v. Ammon The forecast of ED-BPM for the next decades The warning of Roy Schulte (VP of Gartner) since 2006… …we wont 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.

10 10 Rainer v. Ammon Categorizing of ED-BPM use cases Process typeProcess instance Action type {list of domain specific processes} {new, running, all} {instantiate, stop, continue, terminate, change, new define} Development of a taxonomy Example: Use Case Fraud-Management in the Banking-Domain According to the reference model of edBPM-based Fraud-Management, we describe a simple example of the process Withdraw in connection with a potential event pattern of fraud and related processes in order to exemplify the edBPM principle: 1. An instance of a transaction process is started in the case of withdrawing at a certain ATM. 2. A lot of process instances of the same type are instantiated in a more or less short/certain timeframe at different ATMs. 3. Each process step generates an event, if so of different event types (JMS publish/subscribe, special ATM-banking event type according to the banking standard 4. The global event cloud is analyzed in real-time by the CEP-system and optionally by some intelligent components like discriminant analysis and neural networks. A suspicious event pattern is detected because the login-data respectively the card is used more than once and at different locations in a timeframe whereas a service is called in order to check the probability that the same customer could use the same card at the different locations. 5. … [TE1] Tbd [TE1]

12 12 Rainer v. Ammon Modelling of the use cases Typical workpackages before implementing PoCs: SOA-appropriate BP-modeling of the use cases per domain Event-modeling of the use cases and instrumenting process steps and services for an appropriate event generating Definition of BAM-views per use case Description of reference models per use case according to the edBPM/DoReMoPat-pattern framework

13 13 Rainer v. Ammon Pattern 1: Stop one or more running processes upon event This pattern solves the cases ? and ? of para This could be achieved by using the fault handling mechanism available in WS- BPEL In order to activate the corresponding fault handler we can the use event handler that is activated by a complex event occurrence. The event handler throws a fault that stops all the currently running activities. A strong benefit of using loosely coupled event-driven solution is the ability to stop any number of running processes upon a single event: all the processes subscribed to this event will be affected. This is opposed to a conventional peer-to-peer approach that would require explicit sending a request to each one of the processes that should be stopped. Pattern 2: Start a new process instance upon event This pattern solves the cases ? and ? of para Standard WS-BPEL allows starting a new process instance upon an incoming message (via the receive element). We extend the receive element with the ability to specify an event name or an event pattern instead of a message. In order to activate a new process instance the enhanced receive version could be used. If there are several possible events or messages that should start the same process the pick element can be used in a similar manner. Pattern 3: Activate a task or a process in the absence of the expected event within some time period This pattern solves the cases ? and ? of para The absence of some event is an event pattern by itself. It can be specified in an event processing language and detected by an event processing system. Therefore, this pattern is a special case of the above one (start a new process upon event). Pattern 4: Suspend a process and resume upon event This pattern solves the cases ? and ? of para This pattern can be implemented using one of the synchronous BPEL constructs, i.e. receive or pick. For this specific use case (fraud) pick is preferable because it allows handling time out situations, that is what happens if the false positive decision is never made. Pattern 5: Start a process modification/adaptation upon event This pattern solves case 10 of para 3.2. The pattern can be implemented using the enhanced version of the event handler mechanism. The event handler is activated upon an instance of the specified trigger event (e.g. Too Many False Positives). The enclosed activity can modify the BPEL variable that participates in fraud detection pattern calculation, or submits an update request to the event processing system. If the case requires modifying the workflow, the workflow adjustment could be considered as a separate process that is started upon this event. As soon as the new process version is available, it will be activated. The process and possible issues of activating a modified process in presence of an older version of the process is out the scope of this paper.... edBPM-enhancements of standards, e.g. WS-BPEL Master thesis Alex Kofman Technion University Haifa
