Hi Matt,
Thanks a big time for the map. I have looked it and did use your "method" in mapping my IT Architecture. It is a pitty that there is no other efficient way of mapping interdependencies (which are most important for me). In our compamny, most of the IT Arch. parts are implemented as independent projects or as part of bigger projects. Since projects involve budgets and sometimes need to be prioritised, mapping interdependencies is very important in order to make a qualitative and quick decisions.
I will attempt mapping using your methodology (a bit modified) and will let you know on how it came out.
