SOP

Standard Operating Procedure — a documented step-by-step instruction for performing a routine operation consistently.

SOP

SOP (Standard Operating Procedure) is a critical concept in quality, health, safety, and environmental management.

What Is SOP?

A Standard Operating Procedure (SOP) is a detailed, written set of instructions that describes how to perform a specific task or process consistently and correctly. SOPs ensure that activities are carried out uniformly regardless of who performs them, reducing variation, errors, and risk. Key components of an SOP include: purpose, scope, responsibilities, equipment/materials, procedure steps (numbered and sequential), safety precautions, quality checks, references, and revision history. SOPs are required by virtually every management system standard and are typically classified as Level 3 documents (below quality manual and procedures).

SOP Requirements Under UK Law

ISO 9001:2015 Clause 7.5 requires documented information necessary for process effectiveness. FDA 21 CFR Part 211 (pharmaceutical) and 21 CFR Part 820 (medical devices) mandate detailed SOPs for manufacturing processes. GMP requires SOPs for all operations affecting product quality. HSE guidance recommends written safe systems of work for hazardous activities. The document hierarchy typically follows: Level 1 (Quality Manual/Policy), Level 2 (Procedures), Level 3 (SOPs/Work Instructions), Level 4 (Forms/Records). Average organisation with 100+ employees maintains 150-300 SOPs.

Key Components of SOP

  • Manufacturing SOP
  • Quality control SOP
  • Safety SOP
  • Maintenance SOP
  • Cleaning SOP
  • Calibration SOP
  • Emergency response SOP
  • IT/system SOP

SOP in Practice

A cosmetics manufacturer (90 employees) manages 245 SOPs in Q-Hub's Document Hub. When a production process changes, the Process Engineer creates a new SOP revision in Q-Hub. The document enters a 3-stage approval workflow: Technical Review (2 days), Quality Approval (1 day), Plant Manager Sign-off (1 day). Average total approval time: 3.8 days (down from 18 days with paper). On approval, Q-Hub automatically: distributes to 32 affected operators, requires electronic acknowledgement within 5 working days, schedules practical competency assessment, archives the previous version, and updates the training matrix.
