Comments on: Demystifying the Event Driven Gateway http://www.processmodeling.info/posts/demystifying-the-event-driven-gateway/ Insightful information on business process modeling from Rick Geneva Mon, 15 Aug 2011 13:07:11 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Rick Geneva http://www.processmodeling.info/posts/demystifying-the-event-driven-gateway/comment-page-1/#comment-92 Rick Geneva Fri, 05 Feb 2010 22:24:53 +0000 http://www.rickgeneva.com/wp/?p=201#comment-92 Alexandr, Thanks for your comment, and for contributing to this site. You have an excellent question. I'm going to do a quick reply on this now and I plan to do a full post on this topic in the near future, so check back soon. Can you use a multiple event in place of an event driven gateway? Yes. Should you? That's the more important question. The multiple gateway hides a lot of complexity that might be nice to show if those details affect how the process operates. Also, the multiple even is only good for the pattern where any one of the events on the gateway all lead to the exact same activity after an event occurs. An event based gateway allows you to include multiple handling steps after the event occurs. So either all of the events have the same outcome, or you will need a gateway either way. There is an alternate pattern that includes a multiple event, with a data-based gateway immediately after that asks the question "which event was it". So my thought is, just make it an event-based gateway to begin with. This topic deserves more attention. Give me a few days and maybe I can put together some example diagrams. Best regards, Rick Geneva Alexandr,
