By laying out the information in a mind-map, I can have a eagle eye view of the whole project, and then, I can find where the overlaps on the character concept may be. For example, if I'm designing a sci-fi character who is introverted, I might give them a hoodie and a mask, this will make them more comfortable with that character trait, I can see this from a far, by laying out all that I know about the character, before starting to draw. A hoodie, in this case, would not only fit the environment they live in, but it would also be a nod to their personality.
