The future of digital operations – Combine case, process and decision

Blog: Groudlion

Based on last years’ experience in implementing case management solutions, we gained best practices to configure better CMMN models in the Ground lion platform. More specifically, to model more efficient and with more detail for execution in our runtime environment. Furthermore, we became more and more convinced that CMMN, BPMN and DMN have a future together, despite their own focus.

From an analyst perspective

To be clear, these three modelling notations are meant to describe what happens in real life and to be a standard language which leaves no room for misinterpretations. However, using it as a basis to configure and build a user-friendly, operational IT system, is something different.  In our opinion BPMN, CMMN and DMN are three different ways to look at the same reality. Each of the notations can define what is going in its own way. The question we hear frequently is how to decide which notation to use in which situation. Our vision has evolved from ‘choosing between them’, towards ‘combining them’ (if useful), which leads to the closest detail in your analysis. Because, if you look at the same object from every angle, the combination will provide you with the broadest and most thorough overview. One notation highlighting certain concepts more visually explicit than another. Off course this means an analyst should master all three notations…

Let us explain with the example of making a large investment:


From an execution perspective

The modelling part sounds quite logical, right? When using these models directly for execution in an IT system, even more care and detail is needed. If the business operation contains largely ad-hoc and event-based activity, CMMN will make for an easier modelling and starting point. Process fragments inside a case model should be described through BPMN, and system automated decisions through DMN compliant expressions. If your business operation is a clear repeatable sequence of activity, use BPMN as a starting point, including system automated decisions in DMN.
