This week the BCS SPA group held a fascinating session titled “Modelling Choreography” by requirements analyst Ashley McNeile. Ashley described some of the past efforts to model and implement choreographies, using types of process algebra such as  Robert Millner’s Calculus of Communicating Systems (CCS) and its derivative Pi-Calculus. However, Ashley… Read More →

One of the surprising (and for me, interesting) sessions at DEBS 2011 was the edBPM section – where event processing collides with business process management (or business processes, anyway). While much of the BPM world concentrates on workflow-oriented BPM (supported with automated services), there are several interesting areas (or extensions)… Read More →

This might seem an odd question, but there are 2 schools of thought here: An event is a point in time. An event is an activity that can take a period of time. Taking the latter view, we can say things like: Earthquake MMM took place from date-time D1 to… Read More →

IDC’s Stephen Hendrick gave the keynote on the 2nd day of BRForum, titled “BRMS at a Crossroads”. The gist of Stephen’s talk was the need for BRMSs to evolve to the next level. Interestingly this seemed to be the first conference mention of “cloud computing” – a welcome respite from… Read More →

iGoogle duly delivered a reference (but not the referencing blog post) to an interesting IBM Research paper on “providing a new foundation for the Management of Business Operations and Processes”. To summarise (or at least, my interpretion was) : activity diagrams (and by extension, process diagrams) are problematic due to… Read More →

I had promised Prof David Luckham at the last EPTS meeting I would post some notes from a BCS event I attended a while back, given by the IT department of JET. The topic came up again in a response to Tim Bass’ Linkedin CEP blog where Tim implied the… Read More →

Tim Bass recently challenged [*1] the assertion that Complex Event Processing provides “situation awareness” and quoted a Wikipedia article covering this topic from the usual human element. The article interestingly includes a generalized diagram of situation awareness  [reference Endsley, M. R. (1995b). Toward a theory of situation awareness in dynamic… Read More →

… became the topic on one of the last days of OMG this week, with an interesting debate on the relationships between case management and dynamic business processes / activities, records management, and the BPMN roadmap. So what’s on the cards, and what is the relationship to event processing? Firstly,… Read More →

… has hit the newswires [*1,2,3] along with an IDC comment that TIBCO BusinessEvents is “the undisputed CEP leader, with a market share of 40.2 percent”. TIBCO BusinessEvents version 3 has already been in the hands of customers for a few weeks, and has lots of interesting cool features, such… Read More →
