Hi Vyv,
I was trying to ask you what is the territory you wanted to do a map. Since there are many many ways to come up a map, from primitive caveman drawing on their walls telling people where the tiger is hiding to hunt them, all the way towards Google Maps today that helps you to go from point A to point B. Therefore, talking about map is always secondary to talking about your goals/purposes/intentions, and there are many many types of maps (mapping methodologies) exist in your toolbox. The "system map" you talk about might be just one of those tools, and I'm not sure if the members of CYBCOM are familiar with or interested in it. Thus my questions of clarifying your purpose.
For example, if you purpose is to find better methods to enable a group to work together more effectively and efficiently, I would recommend the WINTOP Roundtable Leadership training course. See the following two video clips, short one 2 minutes, longer one about half an hour:
Also if you like to post your thoughts to our Club of Remy as a Call for Discussants, we might be able to do a Zoom meeting if there are two more people interested in your topic.
Regards - Jason
