Scientific performance benchmark of open source BPMN engines

In May 2016, a group of authors from the universities of Stuttgart (Germany) and Lugano (Switzerland) has conducted a profound performance benchmark of three open source BPMN process engines, Camunda being one of them.

As the authors state in their introduction:

„This work proposes the first microbenchmark for WfMSs that can execute BPMN 2.0 workflows. To this end, we focus on studying the performance impact of well-known workflow patterns expressed in BPMN 2.0 with respect to three open source WfMSs. We executed all the experiments under a reliable environment and produced a set of meaningful metrics.“

Besides Camunda, two other well-known …

Camunda Roadshow – [x] done

This and last week we did a roadshow through 7 German speaking cities (Berlin, Hamburg, Düsseldorf, Frankfurt, Munic, Zurich and Vienna). Even if we knew beforehand that there is a lot of interest in Camunda we were surprised by the big amount of people showing up at every single meeting. In total we had more that 550 people in 7 cities! It was an even mixture between business focused roles (like Business Analysts or Project Managers) and technical ones (like Developers). We got a lot of good feedback and so much concrete requests, so I think we will do a …

Camunda Review 2015

For anyone interested in Camunda, here is my 2015 review.

Revenue

Our total company revenue grew by 79%.

They keep using our product and therefore still want the support.
Our customer service is pretty good.

We’re still profitable.

New Camunda Modeler already plays in BPMN Champions League

The brand-new Camunda Modeler based on bpmn.io just proved that it can already play in The Champions League of BPMN modeling. What is The Champions League of BPMN modeling? Well there are dozens if not hundreds of tools that can draw BPMN and produce the process diagrams that we have all come to love in the last 13 years. That is not really a challenge in 2015. The Champions League in terms of BPMN is represented by the Model Interchange Working Group (MIWG) at the OMG. It provides a test suite for training the tools and also organizes live demonstrations …

Neues BPM-Poster jetzt verfügbar

Viele Geschäftsprozesse bestehen aus regelbasierten Entscheidungen, strukturierten Workflows und unstrukturierter Fallbearbeitung. Durch die Integration der OMG-Standards DMN (Entscheidungen), BPMN (Prozesse) und CMMN (Cases) können solche Geschäftsprozesse ganzheitlich modelliert und automatisiert werden.

Das brandneue BPM-Poster visualisiert dieses Konzept mit einem einfachen, aber praktischen Beispiel aus der Versicherungswirtschaft: Wenn jemand eine Kfz-Versicherung beantragt, wird ein BPMN-Prozess angestoßen. Der erste Schritt im Prozess ist ein Business Rule Task, der automatisch feststellt, ob bestimmte Risiken bestehen. Wenn keine Risiken bestehen, kann automatisch policiert werden. Wenn nur Risiken vom Typ „gelb“ bestehen, muss der Antrag manuell geprüft werden, und wenn Risiken vom Typ „rot“ gefunden wurden, …

Why BPMN is not enough

At this year’s BPMCon, some people asked me about CMMN and DMN, and how they are related to BPMN. They were not yet aware that CMMN and DMN are no substitutes for BPMN, but supplements. I have tried to put this in a nutshell here:

BPMN is the right tool if you want to describe business processes that have a certain degree of predictability (or should become more predictable as a result of your process improvement project). If you really know BPMN, you can create process diagrams that are easy to read and directly executable in a BPMN process engine. That …

New BPMN Plugin for WordPress

Wanna show some BPMN?

Do you run a blog, and would you like to to display BPMN diagrams in your posts?

You could draw those diagrams somewhere, export them as PNG or whatever and insert them in your post. But that is not very handy, especially when the diagrams are a bit bigger and people can’t read them anymore. Zooming and out would be nice.

Thanks to Neville Lugton, there is a solution!

You’re a WordPress User?

If yes, read on. If not, get lost.

Install bpmn.io for WordPress

You can install „bpmn.io for WordPress“ directly from the WordPress Plugin Store. Just search for bpmn, …

Why DMN is the next big thing and you will be excited

Every 6 months we publish a so-called „minor release“ of the Camunda BPM platform. The upcoming release 7.4 is scheduled for 30 November, and it will support the new OMG-standard for decision management, DMN.

DMN is currently our priority 1 topic, for a simple reason: We believe, that DMN will become as important for automating decisions, as BPMN has become for automating processes.

I will briefly explain why we think that and then describe how Camunda will embrace DMN, which will make you very excited 🙂

Why DMN is the next big thing – Part 1: The problem

Decision Model and Notation (DMN) – the new Business Rules Standard. An introduction by example.

DMN is a brand new standard of the OMG, it stands for Decision Model and Notation and is clearly related to BPMN and CMMN. DMN defines an XML format and is executable on Decision/Business Rules Engines. It is currently on the home stretch of standardization and camunda will release camunda BPM 7.4 including DMN in November. Over the last months we discussed a lot of Business Rules use cases with clients and sketched solutions in DMN. So high time to give an introduction into DMN and present some learnings we had so far.

The example: Task Assignment/Routing of new claims

The …
