You can edit relationships and element properties directly in matrices. Clicking the selected cell allows for

This feature not only facilitates management of ordinary relationships between elements, but also allows for a faster creation of traceability links between elements, for example, between requirements and the architecture or requirements and test cases. Such an improvement saves huge amounts of time in comparison to linking elements in diagrams. It significantly increases applicability and usability of matrices.

 

To create a new relationship between model elements in the dependency matrix

Commands on the shortcut menu of the cell, for creating a new relationship, depends on criteria specified in the Criteria area of the matrix:

  • Possible relationship types correspond to the types specified as dependency criteria (see solid-line boxes in the following figure).
