(i) Implementation of Governmental Policies and Laws: It is the responsibility of the bureaucracy to carry out and implement the policies of the government. Good policies and laws can really serve their objectives only when these are efficiently implemented by the civil servants.

(ii) Role in Policy: Formulation: Policy-making is the function of the political executive. However, the Bureaucracy plays an active role in this exercise. Civil Servants supply the data needed by the political executive for formulating the policies. In fact, Civil servants formulate several alternative policies and describe the merits and demerits of each. The Political Executive then selects and adopts one such policy alternative as the governmental policy.

(iii) Running of Administration: To run the day to day administration in accordance with the policies, laws, rules, regulations and decisions of the government is also the key responsibility of the Bureaucracy. The political executive simply exercises guiding, controlling and supervising functions. 

(iv) Advisory Function: One of the important functions of the Bureaucracy is to advise the political executive. The ministers receive all the information and advice regarding the functioning of their respective departments from the civil servants. As amateurs, the ministers have little knowledge about the functions of their departments. They, therefore, depend upon the advice of bureaucracy. As qualified, experienced and expert civil servants working in all government departments, they provide expert and professional advice and information to the ministers.
