Last week we reported some interesting statistics about BPMN's adoption in the industry. While the relationship between BPM and SOA is no longer a question, we presented in this article a possible relationship between BPMN, and the standards of SOA: WSDL, WS-BPEL and SCA.
It is no surprise that the activity surrounding BPMN is also increasing rapidly.
In January, the OMG released BPMN v1.1.
About a month ago, Tyler Anderson, published a detailed tutorial on how to "Execute Business Processes with Eclipse" (free after registration) which details how to use the Eclipse SOA Tools Platform (STP) to:
- Install Eclipse STP, Eclipse ATL, the BABEL BPMN2BPEL tools, and Apache ODE
- Model a business process in Eclipse STP
- Transform the Eclipse STP's BPMN format to BABEL's BPMN format
- Transform BABEL's BPMN format to BPEL
- Create an Apache ODE deployment descriptor
- Write Web Service Definition Language (WSDL) for your business process
- Prepare the generated BPEL for deployment Deploy to Apache ODE
Last week, Michael zur Muehlen and Jan Recker published the results of a survey investigating the utilization rate of BPMN constructs. Michael argues:
BPMN is a complex language. [It] consists of 52 distinct graphical elements: 41 flow objects, 6 connecting objects, 2 grouping objects, and 3 artifacts [detailed in a 300 pages specification]. That’s a lot of vocabulary to learn, given that each graphical elements has meaning and rules associated with it. So what is the minimum subset of BPMN that a process modeler should know? The answer: Less than you think.
Bruce Silver, an independent industry analyst and consultant, disagrees somewhat with the approach of this survey.
Stepping back, what he calls the core set of BPMN has, to me, absolutely zero BPMN-ness to it. It’s just flowcharting. In fact, except for message start event, his core plus extended core set is still just swimlane diagrams that have been around for decades.
Bruce also published recently on SAP's Business Process Expert community (BPX) a comprehensive 6 part elearning series on BPMN (free after registration). The second part of the series provides a 20 minute introduction to BPMN.
Antoine Lonjon, from MEGA, just published a white paper on this topic.

Kevlin Henney examines code samples to see what can be learned from them starting from the premise that one won’t write great code unless he knows how to read it.
Jason Ayers share the observations he made watching a team of developers collaborating in real time on the same code base, pushing XP, pair programming and continuous integration to their extremes.
Michael Snoyman presents Yesod, a web framework written in Haskell and containing a web server, templating, ORM, libraries (templating, gravatar, etc.).
Richard Kreuter and Kyle Banker on how to avoid classical RDBMS transactional systems by using compensation mechanisms, transactional messaging or transactional procedures.
Attila Szegedi talks about performance tuning Java and Scala programs at Twitter: how to approach GC problems, the importance of asynchronous I/O, when to use MySQL/Cassandra/Redis, and much more.
One category of risk that project teams need to ensure they address is business value failure – delivering a product that fails to provide value for the business investor.
InfoQ spoke to the authors of Software Systems Architecture on a couple of new topics, the System Context viewpoint and Agile, which have been added to the second edition.
