Many people get promoted early on in their career because of their technical expertise. In order to go to the next level, however, they need to have someone else replace them. Management will likely not promote someone to a higher position if there are no substitutes for that person's current position.

Another reason why many people hit a glass ceiling is because they fail to change their mindframe. As you go up the ladder, you will need "to rally people behind your vision and state your case crisply." It's common sense: going into management is about managing people. Even if you are very good at what you do, but can't manage people, you won't go into "management." In that regard, being effective at communicating with others is key.
