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.
Fishbone Diagram Categories (6M)¶
| Category | Focus Areas | Typical Causes |
|---|---|---|
| Man (People) | Training, competency, workload | Skill gaps, fatigue, communication |
| Machine (Equipment) | Calibration, maintenance, age | Wear, malfunction, inadequate capacity |
| Method (Process) | Procedures, work instructions | Unclear steps, missing controls |
| Material | Specifications, suppliers, storage | Out-of-spec, degradation, contamination |
| Measurement | Calibration, methods, interpretation | Instrument error, wrong method |
| Mother Nature | Temperature, humidity, cleanliness | Environmental excursions |
See references/rca-methodologies.md for complete method details and templates.
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 |

| Specificity | Measurable deliverables | Vague commitments |
| Timeline | Aggressive but achievable | No due dates or unrealistic |
| Resources | Identified and allocated | Not specified |

Effectiveness Verification¶
Verify corrective actions achieved intended results:
- Allow adequate implementation period (minimum 30-90 days)
- Collect post-implementation data
- Compare to pre-implementation baseline
- Evaluate against success criteria
- Verify no recurrence during verification period
- Document verification evidence
- Determine CAPA effectiveness
- Validation: All criteria met with objective evidence; no recurrence observed
Verification Timeline Guidelines¶
| CAPA Severity | Wait Period | Verification Window |
|---|---|---|
| Critical | 30 days | 30-90 days post-implementation |
| Major | 60 days | 60-180 days post-implementation |
| Minor | 90 days | 90-365 days post-implementation |
Verification Methods¶
| Method | Use When | Evidence Required |
|---|---|---|
| Data trend analysis | Quantifiable issues | Pre/post comparison, trend charts |
| Process audit | Procedure compliance issues | Audit checklist, interview notes |
| Record review | Documentation issues | Sample records, compliance rate |
| Testing/inspection | Product quality issues | Test results, pass/fail data |
| Interview/observation | Training issues | Interview notes, observation records |
Effectiveness Determination¶
Did recurrence occur during verification period?
├── Yes → CAPA INEFFECTIVE (re-investigate root cause)
└── No → Were all effectiveness criteria met?
├── Yes → CAPA EFFECTIVE (proceed to closure)
└── No → Extent of gap?
├── Minor gap → Extend verification or accept with justification
└── Significant gap → CAPA INEFFECTIVE (revise actions)
See references/effectiveness-verification-guide.md for detailed procedures.
