Tom Baeyens on jBPM 4.0

Tom’s blog is one of my favorite to keep track of, partly because he takes a fairly pure software engineering approach to the business problem of BPM.  It sounds ironic perhaps, that I would find this interesting, given that our focus at BP3 is all about business process improvement, and *business* results. However, there is something refreshing about Tom’s approach to BPM, as embodied in the jBPM project.  There is also something pure about trying to provide tooling for a problem, without worrying about certain commercial interests that affect the behavior of enterprise software vendors. I still think the commercial vendors are providing an overall user experience that is closer to what the business (and IT) wants out of BPM for truly business-facing processes.  However, efforts like jBPM have a real chance at becoming the de-facto plumbing behind commercial products, by providing (as Tom would put it) a “bottom up” set of foundational building blocks that build up to what you need for a BPM solution. Will jBPM be the chief open source answer to BPM the way that Apache was for web servers?  Too early to tell, and there are other efforts – but if jBPM lives up to its billing, and its core team of contributors keep at it, it seems plausible. I’ve been thinking about what would happen if someone took a very BPMN centric point of view and tried to overlay it on jBPM – could they describe all of the behaviors in jPDL?  Would the Process Virtual Machine (PVM) have all the necessary primitives to support the BPMN aspects?  Could the end-result be tied into an existing modeling framework/toolset? Here’s the slideshow Tom gave at a recent BeJUG meeting:
