Why is it worthwhile for business analysts to model decisions with DMN? The OMG standard pursues a top-down approach, offering a consistent methodology, from the analytical definition of requirements to the operational implementation. We explain four reasons for decision modeling with DMN.
DMN Models Uncover How Value Is Created
The easiest way to get start with DMN decision modeling is via the graphical Decision Requirements Diagrams (DRD). The DMN standard defines some (few) basic elements with which any decision can be fully modeled. The basic elements are shown in the figure below in the palette to the left.
Subject matter experts, business analysts or even IT users create these graphical models via drag & drop in a graphical editor, for example ACTICO Modeler. In this way, they visualize systematically, how a decision is made, what data is needed, which systems and organizational units are involved and which sub-decisions have to be made in advance.
This creates a clear picture of added value in the company. Particularly exciting is the decision modeling in the team. Because not infrequently, teams come to completely new knowledge through the analytical approach. Already that is one reason to model decisions with DMN.
