It’s conventional wisdom in business that 80% of the problems are caused by 20% of the work – the “exceptions.” In BPM, therefore, you’d think that exception handling would be a critical focus of process modeling and analysis. In most cases you’d be wrong.
Certainly the designers of the Business Process Modeling Notation (BPMN) standard at BPMI (now part of OMG) had exception handling in mind from the start. BPMN introduces to process modeling the notion of intermediate events.
