One organizational technique I use often is that of Mind Mapping.

A mind map is a visual way of breaking down ideas and concepts hierarchically. A mind map starts with a central idea or concept and then branching out from that central idea are the keywords that represent the different aspects of that central idea, and, and out until the concept is fully explored or you’ve run out of space on your paper.

While I’ve done paper mind maps for years I have had great luck with using software to rapidly develop mind maps for a variety of purposes such as in project planning and especially in working through a task or concept analysis for instructional design projects.

The two pieces of software that I have used and enjoyed are MindMeister and MindNode.
MindMeister is a free cloud-based tool found here: https://ift.tt/106IvSM which has some excellent collaboration abilities.

MindNode is a MacOS and iOS software that syncs between devices but doesn’t really have the collaborative component the same way MindMeister does. It’s also a bit pricy coming in at about $55 if you go all in. https://mindnode.com/

I’d encourage you to try your hand at mind mapping your current project or challenge. It’s a lovely technique that can help get things organized.
