The Audit Moment of Truth
The auditor asks: "Show me how you control your SOPs."
You pull up a folder of Word documents. Some have version numbers in the filename. Some have approval signatures. Some have neither. The auditor starts taking notes.
This is how nonconformities happen.
Document control isn't about templates that look professional. It's about systems that prove - to auditors, to regulators, to yourself - that you know what's current, who approved it, and what changed.
What Document Control Actually Requires
ISO 9001:2015, clause 7.5.3, requires controlled documents to be:
Identified and Traceable
Every document needs:
- Unique identifier (document number)
- Version/revision indicator
- Title
- Effective date
When someone references "SOP-QA-001," there's no ambiguity about which document.
Reviewed and Approved
Before release:
- Technical review (is it accurate?)
- Quality review (does it meet standards?)
- Management approval (is it authorized?)
Each review/approval documented with name and date.
Available at Point of Use
The people doing the work need access to current procedures. This means:
- Distribution control (who gets copies)
- Access systems (electronic or physical)
- Location management (where documents are used)
Protected from Unintended Changes
Once approved, documents can't be casually edited. Controls include:
- Read-only access for most users
- Change control process for modifications
- Version locking after approval
Subject to Change Control
Changes to approved documents require:
- Change request/initiation
- Review of change impact
- Re-approval
- Communication to affected parties
- Removal of obsolete versions
Retained per Defined Schedule
Retention requirements specify:
- How long to keep superseded versions
- How long to keep obsolete documents
- Format for retention (paper, electronic)
- Destruction procedures when retention expires

Version numbering convention:
- Major version (1.0, 2.0): Significant changes requiring full re-training
- Minor version (1.1, 1.2): Clarifications, corrections, minor updates
Standard Sections
1. Purpose Why this procedure exists. One to three sentences.
2. Scope What's covered and what's not. Where it applies. Who it applies to.
3. Definitions Terms used in the document that need clarification.
4. Responsibilities Who does what. Roles, not individual names (people change, roles persist).
5. Procedure The actual steps. Numbered, clear, actionable. Written in imperative mood ("Record the temperature" not "The temperature should be recorded").
6. References Related documents, forms, work instructions, regulations.
7. Attachments Forms, checklists, flowcharts embedded or referenced.
FDA 21 CFR Part 11 Compliance
For FDA-regulated industries (pharmaceuticals, medical devices, biologics), electronic records and signatures have specific requirements.
What Part 11 Requires for Electronic Documents
Validation: Systems must be validated to ensure accuracy, reliability, and consistent intended performance.
Audit trails: Computer-generated, time-stamped records showing who did what and when. Trails can't be modified.
Access controls: Limit system access to authorized individuals. Unique user IDs, not shared logins.
Electronic signatures: Must be linked to records, include name and date/time, be unique to individual.
Signature manifestations: Printed records must display name, date/time, and meaning of signature (approval, review, etc.).
Implications for SOP Management
If managing SOPs electronically:
- Document management system must be validated
- All access and changes logged automatically
- Electronic approvals meet signature requirements
- System prevents unauthorized changes
- Printouts show complete approval information
Word documents alone don't meet Part 11 unless:
- Stored in validated document management system
- Access controlled through system permissions
- Audit trails generated by system
- Electronic signatures meet regulatory definition
DocMods provides audit trails for document changes, supporting Part 11 requirements when integrated with validated document management systems.
Document Control Process
Creation and Drafting
- Identify need for new/revised SOP
- Assign document number from controlled log
- Draft using approved template
- Save in "Draft" status in document management system
Review Cycle
- Technical review by subject matter expert
- Quality review for compliance with standards
- Changes incorporated from reviews
- Document moved to "Pending Approval" status
Approval
- Final approver reviews document
- Approver signs (electronic or wet signature)
- Effective date assigned
- Document moved to "Approved" status
Distribution and Training
- Document published to controlled locations
- Training requirements identified
- Affected personnel trained on new/revised content
- Training documented in training records
Change Control
- Change request submitted
- Impact assessment completed
- Revision drafted
- Review and approval cycle repeated
- Superseded version archived
- New version distributed
Periodic Review
- SOPs reviewed on defined schedule (annually typical)
- Review confirms continued adequacy
- No change needed = review documented
- Changes needed = change control process
Common Audit Findings
Finding: Obsolete Documents in Use
What auditors see: Old versions at workstations, outdated procedures in binders.
Prevention:
- Controlled distribution with retrieval of superseded versions
- Electronic-only access (eliminates paper version control)
- Watermarks ("UNCONTROLLED IF PRINTED")
- Regular audits of point-of-use documents
Finding: Missing or Incomplete Approval
What auditors see: Signatures missing, dates missing, wrong approval authority.
Prevention:
- Template with mandatory fields
- Approval workflow that requires completion
- Checklist before release
Finding: Inadequate Revision History
What auditors see: Version numbers but no description of what changed.
Prevention:
- Require meaningful change descriptions
- Reference change control or CAPA numbers
- Maintain comparison documents (redlines) in records
Finding: No Evidence of Review
What auditors see: Documents unchanged for years with no evidence anyone verified continued adequacy.
Prevention:
- Defined periodic review schedule
- Review documentation even when no changes made
- Review tracking in document management system
Finding: Training Not Linked to Documents
What auditors see: SOP revised but no evidence personnel were trained on changes.
Prevention:
- Training requirements defined in change control
- Training completion linked to document version
- Training records reference specific SOP versions
Building Your Document Control System
Minimum Viable System (Small Organizations)
- Master Document Log: Spreadsheet tracking all controlled documents, version, status, location
- Template: Standard Word template with required header/approval blocks
- Storage: Shared drive with folder structure (Draft, Approved, Superseded)
- Procedure: Written procedure for document control itself (SOP for SOPs)
Cost: Near zero, just discipline.
Intermediate System (Growing Organizations)
Add:
- Document management software: SharePoint with workflows, or dedicated QMS like MasterControl
- Electronic approval: Built-in signature workflows
- Automatic distribution: Users access from controlled library
- Training integration: Link training records to document versions
Cost: $5,000-50,000/year depending on system and users.
Enterprise System (Regulated/Large Organizations)
Add:
- Validated system: IQ/OQ/PQ validation documentation
- Part 11 compliance: Full audit trails, electronic signatures
- Integration: Connect to training, CAPA, change control systems
- Reporting: Compliance dashboards, audit preparation tools
Cost: $50,000-500,000+ implementation plus ongoing.
Using AI for SOP Development
AI can accelerate SOP creation without compromising compliance:
What AI Does Well
First draft generation: Describe the process, AI generates structured SOP draft following your template.
Consistency checking: AI reviews SOPs for consistent terminology, format, and cross-references.
Gap identification: AI compares SOPs to regulations or standards, flags missing requirements.
Plain language rewriting: AI simplifies complex procedures into clear, actionable steps.
What AI Requires Human Oversight
Technical accuracy: AI doesn't know your actual process - subject matter experts must verify.
Regulatory compliance: AI suggestions may not meet specific regulatory requirements for your industry.
Approval authority: Humans approve - AI assists but doesn't authorize.
Training determination: Humans decide who needs training on what.

The Bottom Line
Your SOP template is only as good as your document control system. A beautiful template in an uncontrolled environment creates beautiful nonconformities.
Build the system first:
- How documents are numbered
- Who approves what
- Where documents live
- How changes happen
- How training connects
Then create templates that support that system.
When the auditor asks "show me how you control your SOPs," you should be able to demonstrate a system, not just show documents. The template is evidence that the system exists. The system is what keeps you compliant.
