From Wikipedia
A standard operating procedure (SOP) is a standardized way of doing a task or the set of step-by-step instructions that document how it is done. SOPs are compiled by an organization to help workers carry out routine operations. SOPs aim to achieve efficiency, quality output, and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations.
