Never Print New SOP Versions Without QA-Issued Control Numbers

Do Not Print New SOP Versions Without QA-Issued Control Numbers

Remember: New or revised SOPs must never be printed or used without an official QA-assigned control number — this ensures traceability and compliance.

Why This Matters in GMP

Standard Operating Procedures (SOPs) form the backbone of GMP systems by defining consistent, validated, and regulatory-compliant processes. Each new version of an SOP must be reviewed, approved, and assigned a unique control number by the Quality Assurance (QA) department to prevent unauthorized distribution, outdated practice, or untraceable documentation use. Skipping this control step leads to confusion on shop floors, improper training, and potential deviation from approved protocols.

For example, printing and distributing an SOP draft without QA authorization might result in incorrect sampling procedures or non-validated cleaning methods being used. This could trigger product contamination, equipment failure, or failed regulatory audits. Control numbers serve as the formal reference for version history, employee training, and revision justification. Failing to follow this protocol jeopardizes the integrity of the document control system.

Regulatory and Compliance Implications

21 CFR Part 211.100 mandates that written procedures must be followed and deviations investigated. EU GMP Chapter 4 requires all documentation to be appropriately authorized,

current, and version-controlled. WHO GMP also highlights the need for unique identifiers for each document version and control over their reproduction and issuance.

During inspections, regulators routinely request a list of current SOPs, control numbers, version history, and issuance logs. Discrepancies between the master list and floor copies, or absence of control numbers, are flagged as major data integrity and document control failures. Unauthorized SOPs may render activities non-compliant, triggering CAPA, batch holds, or inspection observations.

Implementation Best Practices

Establish a centralized document control system managed by QA. Before printing any SOP, ensure that it has been reviewed, approved, assigned a document ID, and issued a control number. Use a master list or document control register to track active SOPs, their revision dates, and assigned locations.

Restrict SOP printing rights to trained QA personnel or document control administrators. Include watermarks or “DRAFT” stamps on pre-approval versions to prevent unintentional use. Train all departments to verify control numbers before SOP use or display. Archive all obsolete versions with a reason for revision and removal date documented.
