> How can a manager evaluate another person's skills when he doesn't have the knowledge in the first place?

Are you wanting to only ever work for people who have a superset of your knowledge? Who know everything you do (for evaluation purposes) but probably also even more? That sounds miserable.

I consider it part of my job to produce results that demonstrate my skill to my manager. I don't want to be micromanaged, and the most effective way I've found to get independence of method is by demonstrating quality of results.
