What is the standard operating procedure (SOP)?

The standard operating procedure (SOP) refers to a specified protocol for executing processes in a consistent manner. SOPs are integral to ensuring that tasks are carried out in a uniform way, which helps maintain quality control, enhance efficiency, and minimize errors in various settings, particularly in fields like bioscience and laboratory work. By providing detailed instructions for specific operations, SOPs help guarantee that all personnel—regardless of their experience level—are able to perform tasks according to the same standards.

In contrast to other options, the role of SOPs extends beyond just safety guidelines, chemical hazard documentation, or equipment categories. While aspects like safety and personal protective equipment are critical in the workplace, they do not encompass the broader function of SOPs, which is to standardize processes across the board. Thus, identifying a standard operating procedure as a specified protocol for executing processes underscores its fundamental purpose in maintaining systematic and safe operational practices.
