Document Lifecycle
A GMP document control system manages documents, most centrally standard operating procedures, through a defined lifecycle spanning drafting, review, approval, distribution, periodic review, revision, and eventual retirement or obsolescence, ensuring at every stage that only current, approved versions are actually in use on the manufacturing floor or in the laboratory. Each lifecycle stage should have clearly defined responsibilities and required approvals, since a document control system with an ambiguous or inconsistently followed approval pathway risks documents entering active use without having received the genuine, substantive review the system is designed to require before implementation.
Version Control
Robust version control ensures every document copy in active use is unambiguously identified by version number and effective date, and that superseded versions are promptly and reliably removed from circulation once a new version takes effect, preventing personnel from inadvertently following an outdated procedure that no longer reflects the currently approved process. This becomes particularly challenging for paper-based document systems, where physically retrieving every distributed copy of a superseded document can be genuinely difficult to fully guarantee, which is a significant part of why many facilities have moved toward electronic document management systems offering centralized, single-source access that inherently eliminates this specific risk.
Access and Training
Document control should ensure personnel have ready access to the current version of any procedure relevant to their role, and that personnel are trained on a new or revised procedure before it becomes effective for their actual use, since a procedure that has been formally approved but not yet trained to the personnel who need to follow it creates a genuine gap between documented expectation and actual practiced behavior on the floor. Training records connecting specific personnel to specific document versions provide important evidence, useful both for internal quality assurance and for demonstrating training compliance during regulatory inspection, that personnel were genuinely trained on the specific version of a procedure they were actually expected to be following.
Retention Requirements
Documents and their associated records must be retained according to a defined retention schedule, typically tied to the product's shelf life plus an additional regulatory retention period, and retained in a form that remains genuinely accessible and legible throughout that full retention period, which for electronic records requires attention to format obsolescence and data migration as underlying systems change over the years of required retention. Superseded document versions should also be retained, even though no longer in active use, since a historical version may need to be referenced during an investigation into a batch manufactured under that earlier version of the procedure.
Periodic Review Requirements
Beyond revision triggered by a specific identified need, documents should undergo periodic scheduled review, commonly on an annual or biennial cycle depending on the document's risk category, confirming the procedure remains accurate, complete, and reflective of actual current practice even in the absence of any specific triggering event prompting revision. This periodic review catches gradual drift between documented procedure and actual practice that might otherwise go unaddressed indefinitely if revision were triggered only by an explicit request or an identified problem, rather than also occurring proactively on a defined schedule.
Electronic Document Management Systems
Electronic document management systems increasingly replace paper-based document control, offering centralized access control, automated workflow routing for review and approval, and built-in obsolescence of superseded versions, but these systems require their own computer system validation confirming the software reliably performs its intended document control functions. Transitioning from paper to electronic document control is itself a significant change requiring careful planning, including a clear approach for handling documents that remain in transition between the two systems during the changeover period.
Handling Uncontrolled or Obsolete Documents
A document control system should include explicit controls preventing use of uncontrolled document copies, such as photocopies or informally saved electronic files that may not reflect the current approved version, and clear marking of obsolete or superseded documents to prevent their accidental future use. Facilities should periodically audit actual documents in use at the point of use, on the manufacturing floor or in the laboratory, to confirm they match the current controlled version according to the document control system, rather than assuming the system's records alone guarantee this alignment without any direct, physical verification.
