Requriment diagram specification


Is there any specification about requirement diagram entities and the possible relations? Is this diagram type an invention of the Visual Paradigm people or is there any standard about this?

Thx Marko

Hi Marko,

I’m sorry for my late reply. You can find the specification of Requirement Diagram in “OMG System Modeling Language (OMG SysML) v1.0” (

If there are any further inquiries, please do not hesitate to contact me.
