DMN – Decision Model and Notation

DMN is a new emerging standard by the OMG (Object Management Group) which can be used for “Business Decision Management”.

It can be integrated seamlessly with BPMN and CMMN and allows modeling complex decision logic as Decision Tables. Such decision tables are understandable by business domain experts but can also be executed directly:

DMN Decision Table

Representing complex decision logic with DMN has many advantages:

  • Compact representation of decision logic
  • Business/IT Alignment: makes it easier for Business experts and developers to collaborate
  • Business Agility: Decision Tables are easy to change and can be redeployed at runtime without changing the application
  • Explicit Versioning: Decision Tables can be explicitly versioned using a repository
  • Auditing and Reporting: executed decision tables can be audited to understand why individual decisions were taken and to aggregate statistics and reports

More introductory information on DMN can be found in the DMN Tutorial.

Camunda 7.4 provides end-to-end DMN Modeling and execution features:

To get started quickly, see the following Example.

New Camunda Modeler

To learn about the new Camunda Modeler, read the Release Blogpost.

Modeling for execution and matching process engine version: Camunda Modeler is compatible with Camunda Process Engine versions 7.4.0, 7.3.3, 7.2.6 or higher. Also please see the migration note about the Extension Namespace URL.

Job Executor Improvements

There are two significant improvements to the Job Executor:

BPMN Heatmap

The BPMN Heatmap is a new feature in Cockpit.
It overlays a BPMN diagram with a “heatmap”, showing the relative frequency with which activities and paths in a process are executed.

The BPMN Heatmap

Or in other words: some tasks are simply “hotter” than others :).

Extended BPMN Support

The release adds support for new BPMN symbols in the process engine.

Most prominently, Escalation is now supported. The support for compensation and signal events has been completed.
The following new events are added:

On top of this, it is now possible to

Extended CMMN Support

Camunda Process Engine now supports CMMN 1.1. Consider the migration note in the update guide.

On top of this, the following new features were added:

New Documentation

We have spent considerable time and effort to give the documentation a complete makeover.
We hope that the new documentation is easier to work with than the old one.

Just compare:

  • Monitoring Camunda Platform 7 with Prometheus

    Monitoring is an essential facet of running applications in a production system. Through this process, organizations collect and analyze data, and determine if a program is performing as expected within set boundaries. When combined with alerting, monitoring allows for detecting unexpected system behavior to mitigate exceptional situations as fast as possible. Furthermore, tracking the performance of a system enables organizations to improve those aspects that have the biggest impact with higher priority. One essential aspect of monitoring is the list of key metrics you want to observe. There are different categories of statistics that can be of interest here. To observe the defined metrics, there are plenty of application monitoring tools on the market today. They differ in many aspects...

  • Securing Camunda 8 self-managed cluster and applications...

    Directory services are an effective way to manage an organization’s users, groups, printers, devices, and more. Most organizations accomplish this using Active Directory, Apache Directory, Oracle Internet Directory, or other similar tools. Recently I worked with a customer who wanted to see how he could secure the Camunda 8 Platform and process applications with such a directory. Their requirements consisted of: Allowing Directory users to access Camunda applications (Tasklist, Operate, Optimize) Accessing secured Tasklist & Operate APIs from our custom project Securing the custom project In this article, I’ll briefly explain the 3 easy steps taken to fulfill their requirements which include: Federate users from the Directory service into Keycloak Declare an application in Identity to access Camunda APIs Configure...
