It can certainly do that...
...if you don't manage people well. Any good manager knows that you have to have SMEs who know more in order to succeed properly.
Basically, a good manager needs to know how to MANAGE, not necessarily how to do the job. As a computer science major with 23 years in high tech, at the end of my corporate career I knew much less about the technical aspects of the work than my people did. After all, they are the SMEs. I knew how projects work, how to manage people and projects, and enough about the different aspects of the project and its technical requirements so that I couldn't get my leg pulled without knowing it (or at least strongly suspecting it).
