SOP
Short for Standard Operating Procedure
A documented, step-by-step process for performing a routine business task consistently and safely.
Definition
A Standard Operating Procedure (SOP) is a written document that describes the exact steps a person or team must follow to complete a recurring task. SOPs exist to drive consistency, safety, compliance, and training efficiency — when everyone follows the same documented procedure, work quality becomes predictable and audit-defensible. A well-written SOP includes a purpose, scope, prerequisites, numbered steps, safety notes, and revision history.
Why it matters
Organizations with documented SOPs have measurably lower error rates, shorter onboarding times, and stronger audit outcomes. Regulated industries (healthcare, pharmaceutical, aviation, food safety) legally require SOPs for many activities. For unregulated businesses, SOPs are the difference between a business that scales cleanly and one where institutional knowledge walks out the door with every resignation.
