How to Link WSDL-Services To BPMN-Processes

Since BPMN2.0 it is not only possible to design processes but to also execute them using a process engine. The process flow has a appropriate visual representation in the standard. But executable processes are mostly data driven. They interact with external services and exchange data with them. In addition to that processes maintain their own internal . . . → Read More: How to Link WSDL-Services To BPMN-Processes

Create Interactive BPMN Models Using JavaScript

In this tutorial I would like to show how to visualize BPMN files in a web browser.
All we need is jQuery for easy DOM navigation, XMLJS to parse the BPMN file and Raphael to visualize it. Since BPMN version 2.0 the BPMN XML file contains additional diagram interchange information. This information together with the actual process . . . → Read More: Create Interactive BPMN Models Using JavaScript

Integrated Process Management with Open Source

If you ever tried to create an execution environment to automate business- or integration processes based on Open Source products, you know that this is not an easy task. Although Open Source products like Activiti or Apache Camel are of high quality, they do not run with production grade quality out-of-the-box. For serious usage scenarios typically . . . → Read More: Integrated Process Management with Open Source

Business Process Evolution and Versioning

(Automated) business processes evolve over time! And they usually evolve faster than IT systems do.
So how can business process changes be delivered to the users quickly?

Let’s look at an example:
Assume we have a process for vacation planning for the staff of a large company. Initially the process was automated based on the knowledge of the human . . . → Read More: Business Process Evolution and Versioning

It is going to take place in several German cities during autumn 2012. I am going to present ways to achive efficiency in the area of process automation using . . . → Read More: Agile Process Management with Open Source

BPMN 2.0 Model Interchange with Enterprise Architect, Signavio Modeler and Activiti Designer

I have been using the Enterprise Architect modeling tool for many projects. I like the tool especially due to its quick modeling capabilities and productivity. Therefore is ideal for workshops with participants from IT and business. Performing live modeling together with the domain experts is a very efficient approach to gather accurate information related to processes . . . → Read More: BPMN 2.0 Model Interchange with Enterprise Architect, Signavio Modeler and Activiti Designer

Executable BPMN for Business Analysts?

People asking for the differences between BPMN and BPEL they often hear BPMN is graph oriented whereas BPEL is block oriented. But what does that actually mean and why is it important?

Block orientation means that there is no way back in the process like a goto statement. In BPEL a common workaround is to use loops . . . → Read More: Executable BPMN for Business Analysts?

Activiti and the Open Source Reference Platform

Now that Activity published the first release (version 5.0) of their Open Source BPMN 2.0 engine and toolset, it was time to integrate it in our Open Source Reference Platform for SOA (OSRP).

Despite some initial weaknesses, such as BPMN error handling, Actitivi is very promising if you are looking for a lightweight, Open Source BPM engine. Especially the . . . → Read More: Activiti and the Open Source Reference Platform

Three challenges of BPMN 2.0

There are three major challenges in using BPMN 2.0 as a holistic (360°) approach to Business Process Management (BPM):

Semantic Alignment
BPMN like all other high-level process languages is context agnostic. This is good, as it allows a wide adoption throughout the industry. On the other hand it means that it does not explicitly express concepts found in business . . . → Read More: Three challenges of BPMN 2.0

Goto is not Evil

Those of you who tried to convert BPMN to BPEL know the “Goto”-Problem which stems from the fact that BPMN is graph oriented while BPEL is block oriented.
This makes it hard to transform one into the other and causes pain in todays BPMN undertakings.
Although goto is banned in modern programming languages, business-like modeling languages definitely need . . . → Read More: Goto is not Evil
