While being detail-oriented, analytical and trained in systematic problem solving might help in some cases, the bigger benefit is the training/experience in changing levels of abstraction.

Sometimes you need to be able to think about long-term industry trends, and other times you need to be able to zoom down to a very specific issue and you need to be comfortable with the nuance that issue involves.
