Answer 3

Now they will begin to advise X-Mind, Mindjet MindManager, freemind, ConceptDraw, Microsoft Visio, LibreOffice Draw, Dia ...)
But maybe there really is something specifically for software development? ..
Interesting ..
(look here, for now ... - https://en.wikipedia.org/wiki/List_of_concept-_and... )
If anything, by the way, here is a picture in Mindjet MindManager on This topic...)) I
also recommend taking a closer look at sourceforge.net/projects/tuftsvue Visual Understanding Environment (VUE) . vue.tufts.edu
I've been looking for something like this for a long time. And now, thanks to this topic, I found it)
Most often I use: X-Mind, less often Microsoft Visio, less often Explain1.5.0.0 , less often TheBrain, even more rarely Mindjet MindManager, less often ThinkBuzan iMindMap, less often Dia and LibreOffice Draw. Now here is the Visual Understanding Environment (VUE) found). Will rise to the first place), or to the second. But it is rather for other purposes.

Answer 5

UML and DFD with pencil or markers. Felt-tip pens are more convenient, because perception is more comfortable in color.
If necessary for the presentation - in Libreoffice Impress.
A complex structure is already a design error. Everything should be primitive and, if possible, multi-level ("divide and conquer" - have you heard that?). On any particular aspect, BL, DFD, functional logic, API - the result should be primitive and fit on one A4 sheet.
If it does not fit, then there is something to divide and simplify. It's very simple.
By the way, well-designed software is written very quickly.
