DMN-diagrams should be given unique names so that they can be structured. The name of a diagram should not be duplicated.
The name of a diagram should reflect the purpose of the decision making process. The name should be oriented towards the output of the top level decision because it is the essential goal of the decision making process.
If you would like to name a diagram within the editor, just click on the default label “New Decision Diagram” on the header and enter the new name.
