RCA (ROOT CAUSE ANALYSIS) IN PHARMACEUTICAL INDUSTRIES
AS PER REGULATORY REQUIREMENTS
1. PROBLEM IDENTIFICATION
What Happens
Clearly define the deviation, OOS, OOT, complaint, breakdown, audit observation, or incident.
Includes
- Deviation description
- Date & time of occurrence
- Product/Batch details
- Area/Department involved
- Immediate impact assessment
- Initial containment action
2. DATA COLLECTION
What Happens
Gather all relevant information related to the event.
Checks
- BMR/BPR review
- Equipment logs
- Environmental monitoring records
- Training records
- Analytical data
- CCTV records (if applicable)
- Interviews with personnel
- Maintenance history
3. INVESTIGATION
What Happens
Analyze the event and identify contributing factors.
Tools Used
- 5 Why Analysis
- Fishbone (Ishikawa) Diagram
- Brainstorming
- Process Mapping
- Trend Analysis
- Fault Tree Analysis
Potential Sources
- Man (Personnel)
- Machine (Equipment)
- Material
- Method
- Measurement
- Environment
4. ROOT CAUSE IDENTIFICATION
What Happens
Determine the true underlying cause of the issue.
Verification
- Supported by evidence
- Repeatable findings
- Data-based conclusions
- No assumptions
- Scientifically justified
Types of Causes
- Human Error
- Procedural Gap
- Equipment Failure
- Material Defect

- Product quality review
- Compliance verification
Acceptance Criteria
- No recurrence observed
- CAPA completed
- Process remains in control
9. RCA REPORT & CLOSURE
What Happens
Document investigation and conclusions.
Report Includes
