An office is primarily concerned with the collection and supply of information. Accurate and up-to-date information relating to the organisation and other agencies affecting the organisation is always required for taking decisions and formulating policies. Besides, the office has assumed many other responsibilities, such as safeguarding assets, personnel management, procurement of assets etc. which are incidental to the primary function. Therefore, the functions of a modern office may be classified into two categories:
(a) Basic functions, and
(b) Administrative functions.
