Citizen Identity Enrolment using BPMN and DMN

Citizen Identity Enrolment using BPMN and DMN At a recent ‘Hack Day’, I decided I wanted to explore a combined BPMN and DMN solution using the latest Camunda implementation. For a use case I settled on identity enrolment. Identity enrolment requires a combination of process, interactive user tasks and is rich in decision logic. Hence a perfect use case for the combined offering. At a high level, identity enrolment can be abstracted to the following pattern. An applicant makes a claim over an identity and presents supporting evidence to substantiate their claim. This evidence is then verified and a decision made based on the weight of supporting evidence, whether the applicant’s claim over the identity is accepted or not. In…

Testing DMN Decision Tables

We did a very successful roadshow the last weeks showing DMN amongst other topics. One thing which was always discussed is how to validate/test DMN decision tables. I want to start with a quote of myself (to give you a good impression on my ego ;-)): When authoring rules in a more agile, business-friendly way, do not forget about testing them in a more agile, business-friendly way. This post shows various approaches discussed on the roadshow.

Converting Excel Worksheets to DMN

Decision Model and Notation (DMN) is the new kid on the block when it comes to defining decisions and business rules. Like BPMN and CMMN, it tries to bridge the gap between human readable definition of business-relevant aspects and technical realization. DMN therefore has a graphical representation as well as an XML-based serialization format and Camunda provides you with a beautiful editor to manage both. So why not go full DMN any minute now? Probably because you work with business rule definitions for much longer than DMN is around and you manage them in Excel. Recreating these with the DMN editor is a tedious task. That is where Camunda’s newest community extension comes into play: The Excel worksheet to DMN…

A new blog for Camunda BPM posse

I was delighted when Daniel asked me to valify (as Robert says) the Camunda BPM Team Blog and make it fit our CI (nope, for once, this ain’t meaning Continuous Integration). Here’s the little story about that work… erm… fun and some show-off about the new blog features.

Impressions from Camunda Community Day 2015

Or in other words: Our most awesome community day yet! Last week our annual Camunda Community Day took place. I always enjoy that day very much because it gives me the opportunity to get in touch with community contributors and users. I always learn a lot during these days and I take a lot of energy away from it. Same as last year, the Community Day took place here at the Camunda office in exactly the same space in which we normally sit behind our desks and write code. We had to limit reservations to 100 (including ourselves). Two things struck me with this: when we announced the date in Camunda Network, it was almost instantly sold out, and almost…

Spring Boot Support in Camunda – new Community Extension

I am very, very excited about this: the Camunda community now actively collaborates around providing support for Spring Boot. This is extremely cool and allows users to deploy Camunda process engine including the Rest Api and the Webapplication in Spring Boot. The project is in a very early stage, if you want to participate, join the ongoing discussion on the dev list and checkout the sources in GitHub! Many thanks to Oliver Steinhauer who provided an initial implementation that the community decided to collaborate around.

Camunda + Liferay Community Meeting

Yesterday evening we met at our Partner Ancud IT in Nuremberg (Germany). Ancud presented their experiences using Portals (namely the Open Source Portal Liferay) in combination with Process Engines (namely Camunda :-)). That was already a topic in a recent webinar, you can check out the recording online: English or German. Afterwards we had interesting discussions about DMN use cases and a “social collaboration hub” research project. But let’s start from the beginning. Camunda + Liferay A process application needs a user interface. According to Ancud experiences this is most often a portal – or at least some home grown portal like thing. Personally I am not yet convinced as we still do a lot of non-portal projects – but…
