Like just about every other productivity technique, “Mind Mapping” has vociferous proponents and those who’ve tried it but never quite made it stick. The general idea is to try to represent a complex but related series of thoughts and topics onto a diagram that helps to organise them, and to aid recall. Mind maps are perhaps more useful for the person doing the mapping as a way of sorting their own brain out, than as a means of communicating to other people or even to record those thoughts for much later consumption.
Like writing a status report, the act of doing the report or compiling the map prompts valuable activity more than the resulting artefact which might never be read. Research has shown that more visually oriented people are likely to get more out of mind mapping, and using a mind map to try to remember stuff has a fairly short shelf life.
If you’ve not tried mind mapping, the simplest way is to start with a blank sheet of paper and a pen. Read some more here about the concepts. Or here, realising that the site is basically trying to sell you mind mapping software. There’s a more balanced view of different software packages, here.
You don’t need to pay for your mind mapping software, though… OneNote could be a great way of doing it, especially if you have a PC with a stylus. There are a few 3rd party addins to OneNote (desktop version) that provide additional functionality for mind mapping, though the same don’t necessarily work with the Modern App version – something that’s been picked up on the User Voice forums.
If you’ve got Visio on your PC, you could try the Brainstorm template, using Visio’s core strength of creating and associating shapes, moving them around, hyperlinking between them as appropriate and so on.
This functional approach can be a bit too structured and formal, some people preferring a much more freehand, flowing kind of mind map to basically do a brain dump. Maybe a good way of publishing an already-sketched mind map?
There are some more brainstorming tips and tricks for Visio 2016 here.
Another option is to try some specific mind mapping software – there are some very good examples of such in the Microsoft Store. One particularly good app is Mind Maps Pro, which is free for a few days (as of end of June 2018 – install it now; even if you don’t try it right away, it’ll save you a good few £/$/€/etc as and when you give it a go).
The app has simple hierarchical mapping features, and some freehand support – including Ink – with easy additions of structure, auto-layout and the like – it’s a great way to creating a mind map on Windows. It can automatically sync your maps to OneDrive, too, and export to PDF/PNG.
