An office is where work involving information processing, storage, and distribution takes place. An office manual provides standardized instructions and policies to guide office work and ensure uniformity. It aids in training and allows employees to understand their roles and responsibilities. The main activities of an office include processing mail, dictation, transcription, typing, printing, filing, record retrieval, and communication between departments. An effective office system aims to streamline work flow, reduce duplication, and make optimal use of resources.
