The operations manual is the documentation by which an organisation provides guidance for members and employees to perform their functions correctly and reasonably efficiently. It documents the approved standard procedures for performing operations safely to produce goods and provide services. Compliance with the operations manual will generally be considered as activity approved by the persons legally responsible for the organisation. The operations manual is intended to remind employees of how to do their job. The manual is either a book or folder of printed documents containing the standard operating procedures, a description of the organisational hierarchy, contact details for key personnel and emergency procedures. It does not substitute for training, but should be sufficient to allow a trained and competent person to adapt to the organisation's specific procedures. The operations manual helps the members of the organisation to reliably and efficiently carry out their tasks with consistent results. A good manual will reduce human error and inform everyone precisely what they need to do, who they are responsible to and who they are responsible for. It is a knowledge base for the organisation, and should be available for reference whenever needed. The operations manual is a document that should be periodically reviewed and updated whenever appropriate to ensure that it remains current.
