CAPA Officer Corrective and Preventive Action (CAPA) management within Quality Management Systems, focusing on systematic root cause analysis, action implementation, and effectiveness verification. Table of Contents CAPA Investigation Workflow Root Cause Analysis Corrective Action Planning Effectiveness Verification CAPA Metrics and Reporting Reference Documentation Tools CAPA Investigation Workflow Conduct systematic CAPA investigation from initiation through closure: Document trigger event with objective evidence Assess significance and determine CAPA necessity Form investigation team with relevant expertise Collect data and evidence systematically Select and apply appropriate RCA methodology Identify root cause(s) with supporting evidence Develop corrective and preventive actions Validation: Root cause explains all symptoms; if eliminated, problem would not recur CAPA Necessity Determination Trigger Type CAPA Required Criteria Customer complaint (safety) Yes Any complaint involving patient/user safety Customer complaint (quality) Evaluate Based on severity and frequency Internal audit finding (Major) Yes Systematic failure or absence of element Internal audit finding (Minor) Recommended Isolated lapse or partial implementation Nonconformance (recurring) Yes Same NC type occurring 3+ times Nonconformance (isolated) Evaluate Based on severity and risk External audit finding Yes All Major and Minor findings Trend analysis Evaluate Based on trend significance Investigation Team Composition CAPA Severity Required Team Members Critical CAPA Officer, Process Owner, QA Manager, Subject Matter Expert, Management Rep Major CAPA Officer, Process Owner, Subject Matter Expert Minor CAPA Officer, Process Owner Evidence Collection Checklist Problem description with specific details (what, where, when, who, how much) Timeline of events leading to issue Relevant records and documentation Interview notes from involved personnel Photos or physical evidence (if applicable) Related complaints, NCs, or previous CAPAs Process parameters and specifications Root Cause Analysis Select and apply appropriate RCA methodology based on problem characteristics. RCA Method Selection Decision Tree Is the issue safety-critical or involves system reliability? ├── Yes → Use FAULT TREE ANALYSIS └── No → Is human error the suspected primary cause? ├── Yes → Use HUMAN FACTORS ANALYSIS └── No → How many potential contributing factors? ├── 1-2 factors (linear causation) → Use 5 WHY ANALYSIS ├── 3-6 factors (complex, systemic) → Use FISHBONE DIAGRAM └── Unknown/proactive assessment → Use FMEA 5 Why Analysis Use when: Single-cause issues with linear causation, process deviations with clear failure point. Template: PROBLEM: [Clear, specific statement] WHY 1: Why did [problem] occur? BECAUSE: [First-level cause] EVIDENCE: [Supporting data] WHY 2: Why did [first-level cause] occur? BECAUSE: [Second-level cause] EVIDENCE: [Supporting data] WHY 3: Why did [second-level cause] occur? BECAUSE: [Third-level cause] EVIDENCE: [Supporting data] WHY 4: Why did [third-level cause] occur? BECAUSE: [Fourth-level cause] EVIDENCE: [Supporting data] WHY 5: Why did [fourth-level cause] occur? BECAUSE: [Root cause] EVIDENCE: [Supporting data] Example - Calibration Overdue: PROBLEM: pH meter (EQ-042) found 2 months overdue for calibration WHY 1: Why was calibration overdue? BECAUSE: Equipment was not on calibration schedule EVIDENCE: Calibration schedule reviewed, EQ-042 not listed WHY 2: Why was it not on the schedule? BECAUSE: Schedule not updated when equipment was purchased EVIDENCE: Purchase date 2023-06-15, schedule dated 2023-01-01 WHY 3: Why was the schedule not updated? BECAUSE: No process requires schedule update at equipment purchase EVIDENCE: SOP-EQ-001 reviewed, no such requirement WHY 4: Why is there no such requirement? BECAUSE: Procedure written before equipment tracking was centralized EVIDENCE: SOP last revised 2019, equipment system implemented 2021 WHY 5: Why has procedure not been updated? BECAUSE: Periodic review did not assess compatibility with new systems EVIDENCE: No review against new equipment system documented ROOT CAUSE: Procedure review process does not assess compatibility with organizational systems implemented after original procedure creation.

Root Cause Validation Before proceeding to action planning, validate root cause: Root cause can be verified with objective evidence If root cause is eliminated, problem would not recur Root cause is within organizational control Root cause explains all observed symptoms No other significant causes remain unaddressed Corrective Action Planning Develop effective actions addressing identified root causes: Define immediate containment actions Develop corrective actions targeting root cause Identify preventive actions for similar processes Assign responsibilities and resources Establish timeline with milestones Define success criteria and verification method Document in CAPA action plan Validation: Actions directly address root cause; success criteria are measurable Action Types Type Purpose Timeline Example Containment Stop immediate impact 24-72 hours Quarantine affected product Correction Fix the specific occurrence 1-2 weeks Rework or replace affected items Corrective Eliminate root cause 30-90 days Revise procedure, add controls Preventive Prevent in other areas 60-120 days Extend solution to similar processes Action Plan Components ACTION PLAN TEMPLATE CAPA Number: [CAPA-XXXX] Root Cause: [Identified root cause] ACTION 1: [Specific action description] - Type: [ ] Containment [ ] Correction [ ] Corrective [ ] Preventive - Responsible: [Name, Title] - Due Date: [YYYY-MM-DD] - Resources: [Required resources] - Success Criteria: [Measurable outcome] - Verification Method: [How success will be verified] ACTION 2: [Specific action description] ...
