Heatmap showing relationship fan-out

[YogaMatt]

(Perhaps this should ultimately be in the suggestions / requests section, but I wanted to see if someone had solved the problem out of the box.)

How to generate a heatmap based on the extent to which model elements are covered by other model elements?
Current problem: showing how business capabilities are fulfilled by the IT components of different vendor offerings; looking for gaps and excessive coupling.
But it is a general problem : how to gauge requirements coverage, as another example.

An idea for how it might be solved out of the box is to run a script over the model elements to set the values of certain tags based on coverage rules. I'd rather not write it afresh but I'm not afraid of recoding if someone has a start point.

Many thanks in anticipation.

And seasons greetings!

Hi there, it's a bit hard for anyone to answer this question for you as they have no idea what meta-model (or even which methodology)  you have adopted for modelling your environment.  Not to mention that you're using overloaded terms in your question.

Hi there Glassboy 
Perhas your question has helped me get to an answer in a way.
I was under the impression that the heatmap chart could be applied generally and widely regardless of the meta-model or the methodology. With the heatmap being a felxible tool, I understood it would be in the way you configure each heatmap that you'd reconcile the variations arising from metamodel/methodological differences. If that is not right, why not?

The flexibility of the heat map functionality is irrelevant when you're asking people to guess how you've modelled your environment.  By forcing people to guess, you're asking people to do a lot of work that is probably going to be wrong.  There is very little to motivate anyone to answer your question.

Taking a wild swing in dark, you want a heat map based on the number of a particular type of incoming relationship, which I don't see a heat map doing for you in a practical way.

Thank you - I suspect you're right that the HEATMAP will not function out of the box as I would like it to.
