SOP means Standard Operating Procedure.

A standard operating procedure is a set of step-by-step instructions compiled by an organization to help workers carry out complex routine operations. SOPs aim to achieve efficiency, quality output and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations.

Every SOP must have the signature of the approving authority within your chain of command before it is a legal document.
