Linking Requirements

After creating requirements on upper (here: stakeholder) and lower (here: system of interest / coffee machine) level they need to be linked in order to create traceability. This can be done easily via drag & drop. To do so, click on the orange chain symbol as indicated below, drag it to the other level, and drop it on the orange/black chain symbol of the target requirement. The linking can be done in both directions and has always the same meaning. It is a direct link between an upper- and a lower-level requirement.
