Audit Planning Workflow
Plan risk-based internal audit program:
List all QMS processes requiring audit Assign risk level to each process (High/Medium/Low) Review previous audit findings and trends Determine audit frequency by risk level Assign qualified auditors (verify independence) Create annual audit schedule Communicate schedule to process owners Validation: All ISO 13485 clauses covered within cycle
Risk-Based Audit Frequency
| Risk Level | Frequency | Criteria |
|---|---|---|
| High | Quarterly | Design control, CAPA, production validation |
| Medium | Semi-annual | Purchasing, training, document control |
| Low | Annual | Infrastructure, management review (if stable) |
Audit Scope by Clause
| Clause | Process | Focus Areas |
|---|---|---|
| 4.2 | Document Control | Document approval, distribution, obsolete control |
| 5.6 | Management Review | Inputs complete, decisions documented, actions tracked |
| 6.2 | Training | Competency defined, records complete, effectiveness verified |
| 7.3 | Design Control | Inputs, reviews, V&V, transfer, changes |
| 7.4 | Purchasing | Supplier evaluation, incoming inspection |
| 7.5 | Production | Work instructions, process validation, DHR |
| 7.6 | Calibration | Equipment list, calibration status, out-of-tolerance |
| 8.2.2 | Internal Audit | Schedule compliance, auditor independence |
| 8.3 | NC Product | Identification, segregation, disposition |
| 8.5 | CAPA | Root cause, implementation, effectiveness |
Auditor Independence
Verify auditor independence before assignment:
[ ] Auditor not responsible for area being audited [ ] No direct reporting relationship to auditee [ ] Not involved in recent activities under audit [ ] Documented qualification for audit scope
Audit Execution
Conduct systematic internal audit:
Prepare audit plan (scope, criteria, schedule) Review relevant documentation before audit Conduct opening meeting with auditee Collect evidence (records, interviews, observation) Classify findings (Major/Minor/Observation) Conduct closing meeting with preliminary findings Prepare audit report within 5 business days Validation: All scope items covered, findings supported by evidence
Evidence Collection
| Method | Use For | Documentation |
|---|---|---|
| Document review | Procedures, records | Document number, version, date |
| Interview | Process understanding | Interviewee name, role, summary |
| Observation | Actual practice | What, where, when observed |
| Record trace | Process flow | Record IDs, dates, linkage |
Audit Questions by Clause
Document Control (4.2): Show me the document master list How do you control obsolete documents? Show me evidence of document change approval
Design Control (7.3): Show me the Design History File for [product] Who participates in design reviews? Show me design input to output traceability
CAPA (8.5): Show me the CAPA log with open items How do you determine root cause? Show me effectiveness verification records
See references/iso13485-audit-guide.md for complete question sets.
Finding Documentation
Document each finding with:
Requirement: [Specific ISO 13485 clause or procedure] Evidence: [What was observed, reviewed, or heard] Gap: [How evidence fails to meet requirement]
Example: Requirement: ISO 13485:2016 Clause 7.6 requires calibration at specified intervals.
Evidence: Calibration records for pH meter (EQ-042) show last calibration 2024-01-15. Calibration interval is 12 months. Today is 2025-03-20.
Gap: Equipment is 2 months overdue for calibration, representing a gap in calibration program execution.
Nonconformity Management
Classify and manage audit findings:
Evaluate finding against classification criteria Assign severity (Major/Minor/Observation) Document finding with objective evidence Communicate to process owner Initiate CAPA for Major/Minor findings Track to closure Verify effectiveness at follow-up Validation: Finding closed only after effective CAPA
Classification Criteria
| Category | Definition | CAPA Required | Timeline |
|---|---|---|---|
| Major | Systematic failure or absence of element | Yes | 30 days |
| Minor | Isolated lapse or partial implementation | Recommended | 60 days |
| Observation | Improvement opportunity | Optional | As appropriate |
Classification Decision
Is required element absent or failed? ├── Yes → Systematic (multiple instances)? → MAJOR │ └── No → Could affect product safety? → MAJOR │ └── No → MINOR └── No → Deviation from procedure? ├── Yes → Recurring? → MAJOR │ └── No → MINOR └── No → Improvement opportunity? → OBSERVATION
CAPA Integration
| Finding Severity | CAPA Depth | Verification |
|---|---|---|
| Major | Full root cause analysis (5-Why, Fishbone) | Next audit or within 6 months |
| Minor | Immediate cause identification | Next scheduled audit |
| Observation | Not required | Noted at next audit |
See references/nonconformity-classification.md for detailed guidance.
External Audit Preparation
Prepare for certification body or regulatory audit:
Complete all scheduled internal audits Verify all findings closed with effective CAPA Review documentation for currency and accuracy Conduct management review with audit as input Prepare facility and personnel Conduct mock audit (full scope) Brief personnel on audit protocol Validation: Mock audit findings addressed before external audit
Pre-Audit Readiness Checklist
Documentation: [ ] Quality Manual current [ ] Procedures reflect actual practice [ ] Records complete and retrievable [ ] Previous audit findings closed
Personnel: [ ] Key personnel available during audit [ ] Subject matter experts identified [ ] Personnel briefed on audit protocol [ ] Escorts assigned
Facility: [ ] Work areas organized [ ] Documents at point of use current [ ] Equipment calibration status visible [ ] Nonconforming product segregated
Mock Audit Protocol
Use external auditor or qualified internal auditor Cover full scope of upcoming external audit Simulate actual audit conditions (timing, formality) Document findings as for real audit Address all Major and Minor findings before external audit Brief management on readiness status
