Comment on Demystifying the Event Driven Gateway by Rick Geneva

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

Rick, could you explain difference between Event-based gateway and Multiple event?

Comment on Highlights from BPMN 2.0: New Event Types by Rick Geneva

Kim,
Thanks for the comment.
I have to confess I’m getting a bit behind on my postings. I have to balance writing in this blog with writing in my next book the Microguide to Processs Modeling in BPMN 2.0. I’m pushing hard to get it on the market by early Q2. Initially my writing partner and I thought we’d do just a quick update to the last book. But after digging deep into the BPMN 2.0 spec we realized that we are looking at a total rewrite. Much has changed in the spec, and along with this changes our recommendations and patterns are changing as well.

I believe you are correct. I forgot to enclose the escalation path into the dashed subprocess (in-line subprocess). Thank you for pointing this out. I will correct it soon. I could have said that I was planning to do this in a later post and my diagram was deliberate, but you would have called me out on that, wouldn’t you? So maybe the next post in the series will be about subprocess, in-line subprocess, and stand-alone subprocess. This topic needs to be addressed anyway. So thanks for your contribution to my site.

Hi Rick,

Thanks for a helpful site, in as plain a language as one can get with BPMN

It’s my understanding from the BPMN 2.0 spec (page 218) that “The Escalation Start Event is only allowed for triggering an in-line Event Sub-Process.” If that’s the case, then I think in your “Escalation Event Example (non-interrupting) picture above, you need to show the handle escalation within an Event Sub-process. Or do I misunderstand the spec?

Greg,
Thanks for helping to spread the word. Keep your eye out for the next update. I’m a bit behind due to customer workload on the day job, but I should have another one out before the holiday.

Comment on Highlights from BPMN 2.0: Event Gateways by Rick Geneva

Rick Geneva — Thu, 03 Dec 2009 03:30:08 +0000

Greg,
Good to hear from you, and thanks for your kind comments. There’s a lot of nice things about BPMN 2.0. There are many use cases now covered that were neglected before. Now the problem isn’t so much how to create a diagram, but rather which way is the best, of the many options that will achieve the same results. Subtle differences make all the difference in diagram interpretation, and process execution optimization. My first round of blog posts is going to cover what’s new in BPMN 2.0. After this I plan on writing some more on the use cases and the problems that are solved. The hardest part of the new spec is understanding what has changed. There’s a lot of new stuff in the diagrams, and I haven’t even touched the mapping to BPEL yet.

Rick,

I agree with your assertion about the event based inclusive gateway.
When adopted by BPM vendors, it will definitely simplify process triggers (be they intermediate or instantiation) based on a combination of received events.

Good job with the Blog by the way.

Cheers,
Greg
