Should a manager (or CEO) in an IT company have an IT background to perform in the organization?
My project manager at the company I work at, has no technical knowledge in the websites we build.
I think this is obviously acceptable, however when we get questions about how certain parts of the website work, I have to answer the questions.
Is it quite common for a project manager to not know the details of how each project works? And should this be the case?
