On this occasion, I spoke of using technical debt as part of the evaluation of a portfolio of applications, along different axes. After this post, I was thinking about what I could do with a 3D graph of such a portfolio, using the eXcentia’s plugin ‘3D City Model’ (1).

I have already presented this plugin in previous articles: City Model, City Model – New release, Critical City where I explained how to customize the 3D graph using our own formulas, and finally the ABC metric to investigate the metric of the same name. Continue reading →
