Thankfully, Tom Debevoise and James Taylor have recently joined forces to address the drought of books on DMN and its integration with BPMN. They have updated the former’s Microguide to Processing Modeling in BPMN to include decision modeling and published it as the Microguide to Process and Decision Modeling in BPMN/DMN. As an admirer of both Tom’s precise, example-laden earlier work and James’ impressive work on decision management, I have a very high opinion of their book. See why here… (more…)

The tasks therein not only have no stipulated running order, they don’t have to execute at all. Until recently, when modelling business processes, I’d use ad-hoc processes to denote business activities for which order was irrelevant or ‘unknowable’. But the use of BPM tools has thrown up a new rationale for ad-hoc processes. One which may make their use considerably more common… (more…)

I now understand that, in some cases, this ability to select jobs is the last thing workers or the SMEs really want… (more…)
