Roadmap

What is BPM?

A business process is a process that describes
the order in which a series of steps need to be executed,
using a flow chart.

Business Process Management

Why BPM?

Visibility

Monitoring

Higher-level

Continuous improvement

Speed of development

Increased agility

Key Characteristics

Open-source, lightweight

Native BPMN 2.0

High-level business processes

Business user & developer collaborate


Modularized, pluggable, standards


(One of the) most advanced open-source BPMN2 engine

Adaptive, ad-hoc, dynamic processes

Integration and unification with business rules and complex event processing

Service Repository

Example: Notification

[ [ "name" : "Notification", "parameters" : [ "Message" : new StringDataType(), "From" : new StringDataType(), "To" : new StringDataType(), "Priority" : new StringDataType(), ], "displayName" : "Notification", "icon" : "icons/notification.gif" ]]

Example: Notification

class NotificationHandler implements WorkItemHandler { public void executeWorkItem(WorkItem wI, WorkItemManager manager) { String from = (String) wI.getParameter("From"); String to = (String) wI.getParameter("To"); String m = (String) wI.getParameter("Message"); // send email EmailService service = ...; service.sendEmail(from, to, "Notification", m); manager.completeWorkItem(wI.getId(), null); }}

class NotificationHandler implements WorkItemHandler { public void executeWorkItem(WorkItem wI, WorkItemManager manager) { String from = (String) wI.getParameter("From"); String to = (String) wI.getParameter("To"); String m = (String) wI.getParameter("Message"); // send email EmailService service = ...; service.sendEmail(from, to, "Notification", m); manager.completeWorkItem(wI.getId(), null); }}

Ready for the future?

Traditional BPM systems have problems with change, complexity, flexibility, data-intensive applications, etc.

Adaptive Case Management (ACM)

Unstructured, non-lineair or flexible processes

Event-driven BPM (edBPM)

Motivation

A business solution usually involves the interaction between these technologies.Technology overlap

Business overlap

Attribute the same importance to the three complementary business modeling techniques

Events

Processes
