First, I start with my brainstorming notes. By this time, I have a bunch of random plot ideas, mini scenes, and sometimes even snippets of dialogue written down. I like to go through and highlight which ideas I intend to use then start putting them in order chronologically. Next, I start filling in the blanks and adding substantive details. For example, if two of my ideas involve being on different planets, I'll figure out how the characters traveled and if anything eventful happened along the way.
For Renegades, I wrote out about 200 index cards with one sentence descriptions of the major plot points I was going to put in my outline.

For a more visual person like myself, seeing the book laid out was very helpful. Here's an example I found with post-its:
Lastly, I typed up my outline in a typical outline format, like this:
