Your personal network is a very valuable resource. It does matter who you know and by whom you are known. Organizational theory and management have obvious connections. You are constantly applying your knowledge of how organizations function just to stay on top of your job. Such an understanding, however, is not a part of some other disciplines.
General theory is also quite valuable.
This is the essence of sociology and theory is an important tool in understanding, or framing some situation. So often people get caught up in the local or immediate issues. Sociological theory helps one see the larger and longer range picture. In addition to theory, methodological skill is always in demand. But beyond competence, you must be creative.
