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.

BPMN and Decision Tables

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

There is a new kid on the block of BPM Blogs: Our tech lead Daniel Meyer started blogging, and since Daniel strives for excellence in anything he does, I would strongly recommend to

follow him on twitter and
read his latest post about how to express asynchronous service invocations in BPMN.

From Push to Pull – External Tasks in BPMN processes

Push vs. Pull

A process engine typically call services actively (e.g. via Java, REST or SOAP) from within a Service Task. But what if this is not possible because we cannot reach the service? Then we use a pattern we called “External Task” – which I briefly want to describe today.

Picture on the right taken from – thanks!

Context and problem

A couple of recent trends increased the need for this pattern, namely:

Cloud: When running process/orchestration engines in the cloud you might not be able to reach the target service via network connections – and VPNs or Tunneling is always cumbersome. It is …

Orchestration using BPMN and Microservices – Good or bad Practice?

Orchestration and Microservices

Martin Fowler recommends in his famous Microservices Article: “Smart endpoints and dumb pipes”. He states:

The microservice community favours an alternative approach: smart endpoints and dumb pipes. Applications built from microservices aim to be as decoupled and as cohesive as possible – they own their own domain logic and act more as filters in the classical Unix sense – receiving a request, applying logic as appropriate and producing a response. These are choreographed using simple RESTish protocols rather than complex protocols such as WS-Choreography or BPEL or orchestration by a central tool.

I do not agree! I think even – …

This was not about Sales or Marketing, but just about showing-off the things we’re proud of, and showing it off to peers who understand and appreciate the passion behind it.

But bpmNEXT is even more, it is the global gathering of a …
