Can a nontechnical person holds the position of a technical department

I have a query that can a non technical person be a head of technical department just because he is an IAS. Most of the technical departments in state government such as District Development Authorities, Power etc. have an IAS as the VC or MD who sits over experienced and senior technical persons without having any technical know abouts and thus ensuring that right decisions are not been taken for the developmnent of people. Also there is no fixed rule defined for giving these posts to bureaucrats. If the revenue of authority is high then it is given to a senior IAS eg. Noida Authority and if revenue is less it is given to a PCS or Junior IAS eg. Saharanpur Authority. The country is fast becoming slave to ego of bureaucrats
