Relationship Matrix and traceability

[MichaelB123a]

Hi,

I'm using the Relationship Matrix to map requirements to components, test cases etc.

I've set up two tiers of requirements - we have a whole bunch of customer requirements from different customers and then a rationalized set of product requirements.

I've currently mapped product requirements to one or more customer requirements. The product requirements are also then mapped to test cases with a trace association.

The trouble I'm having is using the Relationship Matrix to see the indirect relationships between a customer requirement and a test case:

customer reqt <-> product reqt <-> test case

I presume this is down to the Relationship Matrix only supporting one-hop relationships? Is there any way of achieving this if I were to change the type of relationships? For example, if I made the customer reqt a specialization of the product reqt? (tried that, didn't work   )

Maybe it's not possible, just wanted to see if it might be. Any help would be very much appreciated.

Thanks,

Michael

You are correct, the relationship matrix is for direct relationship maintenance. An alternative in the GUI is to use the traceability view - it shows all the connections for a selected element, you can also create it on diagrams for an element at a time using 'Insert Related Elements'.  If you need to get the information in a report and the supplied functionality does not work for you then you may need to use a SQL query as the source for the output.

Thanks very much for your reply, I'll figure out another way of doing this.

Yes, the request to be able to report on traceability in this way without needing to craft your own SQL has been out there for a very long time.
