BPMN and DMN for Processing Business Data with Camunda

Andr辿 Borgonovo
Andr辿 Borgonovo

Camunda is an open source platform that can be used to model and execute BPMN and DMN processes. The presenter's organization used Camunda to empower business analysts to build and validate business rules without IT intervention. They modeled BPMN processes with start/end events, gateways, and service tasks pointing to decision tasks using DMN. While the Camunda modeler had some bugs, they were ultimately able to process over 100k records and 25M child records. Involvement of business analysts in rules improved the project, and decision tables helped organize complex rules.

INTRO BPM = Business Process Management BPMN = Business Process Model and Notation DMN = Decision Model and Notation
PROJECT VISION AND GOAL WHY WE WANTED TO USE BPM? Empower Business Analysts on having access to data processing Business Rules, so they can build it by their own and check its validity and consistency. Therefore the Business Areas are partially free to evolve without IT intervention.
THE TOOL WE CHOOSE Camunda is an open source platform for workflow and business process management. You can model and execute BPMN 2.0, CMMN 1.1 and DMN 1.1. Free & Open source Customized code is created with well-kown languages such as Java, Groovy and Javascript They have their own Modeler Enterprise version with enterprise support Trusted by big players like Allianz, Generali, Red Bull and Zalando

BPMN IN CAMUNDA OUR APPROACH No custom code on any other IDEs (Eclipse) The BPMN processes were modeled with: Start events, Gateways and End events Service Tasks (with Groovy scripts) Service Tasks (for HTTP Connectors) Decision Tasks (pointing to DMN)
DMN IN CAMUNDA OUR APPROACH Business Analysts have full access to Decision Tables Technical team Works on it for preparing the name of variables and planning the Hit Policy. Then they work for consuming it from the BPMN process definition.
ARCHITECTURE
SOME CONSIDERATIONS To take the initial steps on Camunda we had a hard time. When a professional with previous experience entered the game, we really started making good steps; Camunda team is very available, but for professional support you need to hire them (they say the Enterprise Support). The other option is to take the community support, which was nice when we needed; Even if it seems to be right, test it and test it again! Camunda Modeler has some weird bugs, but in the end of the day you can work with it. Keep your services that will communicate with Camunda on the same Resource Group (same network) avoiding problems with slow data transfer through the Internet;
IMPRESSIONS & RESULTS Involvement of Business Analysts on rules that are actually used by the product is very beneficial for the project; Decision tables simplify long lists of rules, helping on organization and clarification; You can use Camunda without Eclipse (which is nice), but you need to know Groovy and code in a poor IDE for coding. We took Camunda for processing, in the first data load, plus than 100K records, plus around 25M child records. Camunda can handle it, but you need to plan and architecture its infrastructure pretty well.
