Last week I was pulled into the tail end of a project which had just got pushed back to the end of February for complications. The project was now billed at 3 guys, 3 weeks. After spending an hour in a meeting I came up with a solution that is going to be implemented on Tuesday by one guy. Same risk, but a fraction of the work.
I know most of the time when you think about 10xers you think about some kind of math / programming / algorithm god, but don't discount big picture skills. Unfortunately I'm not sure how you teach big picture skills or put them down on a resume.
