The term standard operating procedure, or SOP, is used in a variety of different contexts, including healthcare, aviation, engineering, education, industry, and military.

The U.S. military sometimes uses the term Standing — rather than StandardOperating Procedure, because a military SOP refers to a unit's unique procedures, which are not necessarily standard to another unit. "Standard" could imply that there is one (standard) procedure to be used across all units.

Procedures are ongoing processes with unlimited ending time frames, while projects have definite starting and ending points. Installing a unit, or establishing a business, is a project with tasks that ends at point the unit or business is "standing". The term SOP means the procedures that are executed after the unit or business "stands". Hence, standing operating procedures.

Clinical research and practice[edit]

In clinical research, the International Conference on Harmonisation (ICH) defines SOPs as "detailed, written instructions to achieve uniformity of the performance of a specific function". SOPs get usually applied in pharmaceutical processing and for related clinical studies. There the focus is always set on repeated application of unchanged processes and procedures and its documentation, hence supporting the segregation of origins, causes and effects. Further application is with triage, when limited resources get used according to an assessment on ranking, urgence and staffing possibilities.[1] Study director is mainly responsible for SOPs. The Quality Assurance Unit are individuals who are responsible for monitoring whether the study report and tests are meeting the SOP. SOP's can also provide employees with a reference to common business practices, activities, or tasks. New employees use an SOP to answer questions without having to interrupt supervisors to ask how an operation is performed.[citation needed] The international quality standard ISO 9001 essentially requires the determination of processes (documented as standard operating procedures) used in any manufacturing process that could affect the quality of the product.[2]
