If you haven’t used Mind Mapping software before, it basically is a node based visual schematic builder. Mind Maps allow users to quickly and easily put together a tree based node structure. You can show a hierarchy of Ideas, Objects, Options, Processes and just about anything else you can think of. Nodes can be titled, color coded, and referenced. Most Mind Map software allows you to expand and contract different child node trees with their parents and branching nodes.
When brainstorming for one of my own projects I used it for a broad range of concepts. This way I could give a full presentation on the scope of the work and all it’s parts. This tool is helpful when trying to communicate the website structure and functionality. Sometimes side project would go cold after getting swamped with work. A clean mind map made easy to reference again and jump back on it later that year. I can’t tell you how much time it saved us when everyone had to switch gears and try to get on the same page again.
