Visual matrix model type to represent many-to-many relationships

Good Day,

I have been contemplating a matrix model for some time, and would like the community's comment on this idea, or ways to represent the same concept without cumbersome connection attributes, etc.

I would like to know what the possibility is of a proper graphic matrix model in future – one where the row and column objects are reused from database models, and connections, with descriptions, are created by putting a suitable connection “object” into the appropriate cell.  The model that seems to look a bit like this is the Balanced Scorecard Model.  In order for this matrix model to work, there should be no restriction on what objects can be used as the row/column objects, and no restriction to connect any two objects via a third object in a cell.

An example of a possible view of such a model is shown below:

Example Uses:

1. Compare what requirements are satisfied by which solution capabilities
2. Compare As-Is components to To-Be components, in a graphical format.
3. Any association that represents many-to-many relationships, eg. Risks and controls, where one control mitigates several risks, while one particular risk may have several controls.  By allowing the “connection object” to be placed in a FAD, it would further allow the particular context to be included in the process models, since each connection object represents a unique case.

Your comments are most welcome.
