I understand that you feel frustrated; your role does not match your expectations. So maybe you should find out the meaning and the purpose of your role. In the end, you are paid for adding value in the corporate environment; your contribution can happen in many ways, e.g. by hosting more effective meetings or by improving decision frequency and speed etc. Adding value in a corporation is not always about technical achievements, but also about improving the team and the game (as a social process). If this is not your cup of tea, you might be better served by a technical role in some specialized consulting company.
