Standard Operating Procedure (SOP), often shortened to "the SOP," is a standardized plan adopted by an organization for the orderly and efficient carrying out various activities such as work, production, or services. The SOP is a company-wide standard that includes everything from greeting your coworkers in the morning to what to do if there's a fire. While it may appear overly restrictive at times, its goal is to minimize variation and mistakes. Every business activity has at least one best practice that can lead to success and efficiency if adhered to deliberately and consistently.
