+
+### 5.1 Corrective Action Process
+
+Corrective actions are initiated in response to identified nonconformities from sources including:
+
+**Sources of Nonconformities:**
+- Customer complaints (per SOP-[NUMBER])
+- Internal nonconforming product (per SOP-[NUMBER])
+- Internal audit findings (per SOP-[NUMBER])
+- Process monitoring out-of-specification results
+- Product inspection failures
+- Supplier nonconformances
+- Regulatory inspections or observations
+- Management review action items
+- Risk management outputs
+- Returned or rejected product
+
+**5.1.1 CAPA Initiation**
+
+1. When a nonconformity is identified, the individual discovering it:
+   - Completes a CAPA Request Form (Attachment A) or enters information into CAPA system
+   - Describes the nonconformity clearly and completely
+   - Attaches supporting documentation (NCRs, complaints, audit findings, etc.)
+   - Submits to Quality department
+
+2. CAPA Coordinator:
+   - Receives CAPA request
+   - Assigns unique CAPA number: CAPA-[YEAR]-[###]
+   - Logs CAPA in tracking system
+   - Routes to Quality Manager for review
+
+3. Quality Manager:
+   - Reviews CAPA request for completeness and clarity
+   - Determines if corrective action is warranted
+   - Assigns priority (see Section 5.3)
+   - Assigns CAPA Owner
+   - Sets due date based on priority
+   - Approves initiation of CAPA investigation
+
+### 5.2 Preventive Action Process
+
+Preventive actions are initiated proactively to address potential problems before they occur.
+
+**Sources of Preventive Action:**
+- Trend analysis of complaints, NCRs, or other data
+- Risk management activities (per SOP-[NUMBER])
+- Process capability studies
+- Near-miss events
+- Lessons learned from other organizations or devices
+- Changes in regulations or standards
+- Proactive process improvements
+- Management review outputs
+- Employee suggestions
+
+**5.2.1 Preventive Action Initiation**
+
+Process is similar to corrective action (Section 5.1.1), but:
+- Describes potential nonconformity and its possible consequences
+- Includes data or rationale supporting the need for preventive action
+- May have different prioritization based on risk of occurrence
+
+### 5.3 CAPA Prioritization
+
+All CAPAs are prioritized based on:
+- Severity of impact (safety, regulatory, customer impact)
+- Frequency or likelihood of occurrence
+- Detectability before reaching customer
+
+**Priority Levels:**
+
+| Priority | Criteria | Due Date for Completion |
+|----------|----------|-------------------------|
+| **Critical** | Safety issue, regulatory requirement, major customer impact, Class I recall potential | [X] days |
+| **High** | Significant quality impact, repeat issue, moderate customer impact, regulatory reporting | [X] days |
+| **Medium** | Moderate impact, isolated occurrence, minor customer impact | [X] days |
+| **Low** | Minor impact, isolated occurrence, no customer impact, improvement opportunity | [X] days |
+
+Priority is determined by Quality Manager in consultation with CAPA Owner and affected department managers.

+
+**For Simple Issues:**
+- 5 Whys technique
+- Cause and effect analysis
+
+**For Complex Issues:**
+- Fishbone (Ishikawa) diagram
+- Fault tree analysis
+- Failure mode and effects analysis (FMEA)
