هم اکنون حدود يک سال از انتشار آخرین نسخه زبان مدلسازي فرآيندهاي کسب و کار (BPMN) تحت عنوان BPMN 2.0 مي گذرد. ورژن 2 از استاندارد BPMN يکي از ورژن هايي است که مدت زمان طولاني براي ارائه آن همگان منتظر بودند و طبق اظهار نظر OMG، يک نسخه تکامل يافته و پايدار مي باشد. به همين خاطر است که از سال گذشته تا کنون هيچگونه زيرورژن يا اعلاميه اي توسط OMG در خصوص BPMN منتشر نشده است.

He notes that versions 1.1 and 1.2 were successful in part because they allowed business analysts to create process diagrams that were expressive and rich enough to address complex issues such as exception handling. That meant it was possible for process-execution vendors to use BPMN as the activity-flow layer of the executable design, to which they could simply attach the execution detail to each shape in the process diagram without having to redo the diagram in a different language.

However, says Silver, that detail wasn’t standardized. Thus, each vendor tool handled the task in it in its own way. Of course, he acknowledges, not every company wants to commoditize its run time. So even with some of the industry's biggest players having fully fledged process execution based on BPMN 2.0, many others will continue to do it their own way—and, Silver adds: "There will be all the usual finger-pointing about whether or not your product is based on the standard."

Another change in BPMN 2.0 relates to the concept of choreography. The underlying idea is that "a set of processes form choreography if they communicate and there is no overarching process in charge of it," explains Jon Siegel, OMG's vice president for technology transfer. He says BPMN is fantastic at modeling, but the addition of choreography represents a major step forward in version 2.0. He says choreography was inserted belatedly because BPMN was first designed and came into widespread use a time when there wasn’t as much Internet-based commerce and choreographic processes were unusual, if they happened at all.
