The idea map is another useful planning technique for writers wishing to work offline. Similar to mind mapping and concept mapping, the idea map helps writers to lay out ideas before drafting.
The illustration shows a completed idea map created by a scientist proposing the hiring of two researchers for his lab. During the brainstorming phase, he grabs a sheet of blank paper and a bunch of varied color makers. First, he draws a circle in the middle of a sheet with his topic: "need two researchers." Next, he draws spokes from the circle, one color per spoke, to highlight the supporting points: benefits, problem, causes, recommendations, plan. Then come more sub-points and sub-sub-points within those supporting ones.
For the organizing phase, he structures the points as they will appear in his draft, starting with the ask (1. need two researchers), following the listed numerical and alphabetical order. You can imagine what this writer will be discussing in his proposal by reading the idea map he has created.
