Most interdepartmental communication is done over phone, but when the information has to be communicated in writing then memorandums are used. Memos are also issued in the cases of disciplinary actions to be taken against employees. The format of a memo is almost the same.
Office circulars are used to convey the information to a large number of employees. It is used for internal communication, so it is brief and formal.
The format of office orders is similar to memorandum but the purpose for which it is issued will differ. It is usually issued in matters affecting rights and privileges of employees. Office order carry a number since it will be in force till revoked.
