1. Brief Description:
The Post Risk Analysis for the Automatic Vertical Round Bottle Sticker Labeling Machine (Cepha Block) evaluates equipment-related risks after qualification and during its intended use in powder oral dosage manufacturing. The machine is designed for labeling round bottles at approximately 100–120 containers per minute, depending on product and label size. The assessment follows the FMEA methodology in line with ICH Q9 and evaluates potential failure modes using Severity, Occurrence, Detection, and Risk Priority Number (RPN). Key areas assessed include design and installation qualification, reference-document availability, MOC verification, calibration, operational checks, safety features, equipment controls, cleaning, machine speed, and change control. Risks are classified as Critical, Major, Moderate, or Minor, with CAPA required for RPN values above 25. The report also includes risk-control measures, post-action review, summary, conclusion, and final approval by Head-QA.

The flow diagram presents the systematic Post Risk Analysis process for Automatic Measuring Cup Placement (Cepha Block) using the Failure Mode and Effects Analysis (FMEA) methodology. The process begins by defining the equipment, objective, scope, and risk-assessment approach. The multidisciplinary team includes Quality Assurance, Production, Quality Control, Engineering, and Store, with ICH Q9 used as a key reference.
Potential failure modes, their causes, and possible effects are identified and evaluated by assigning Severity (S), Occurrence (O), and Detection (D) ratings. The Risk Priority Number (RPN = S × O × D) is then used to determine the risk level and need for control measures. Risks requiring improvement are controlled through appropriate corrective actions and subsequently re-evaluated. The final stage includes review of residual risk, preparation of the risk-assessment summary and conclusion, documentation of control measures, and final approval by Head-QA, confirming that identified risks are adequately controlled.
3. Brainstorming – Post Risk Analysis for Automatic Measuring Cup Placement (Cepha Block) Not Prepared:
The Post Risk Analysis for Automatic Measuring Cup Placement (Cepha Block) is intended to verify that risks associated with the equipment remain adequately controlled after installation, operation, performance, and safety considerations have been assessed. The approved methodology specified in the document is FMEA (Failure Mode and Effects Analysis), with participation from Quality Assurance, Engineering, Production, Quality Control, and Store.
If the post-risk analysis is not prepared, identified failure modes may not be formally reassessed, residual risks may remain undocumented, and the effectiveness of existing control measures may not be demonstrated. This can result from inadequate FMEA knowledge, unclear responsibility, incomplete technical information, insufficient cross-functional involvement, or lack of timely review. The FMEA process requires evaluation of Severity, Occurrence, Detection, and RPN, followed by suitable risk-control actions where required. Therefore, the post-risk analysis should be completed, reviewed, documented, and approved to provide evidence that remaining risks are acceptable and adequately controlled.
4. 5-Why Analysis – Post Risk Analysis Not Done:
The 5-Why Analysis identifies the underlying reasons why the Post Risk Analysis for Automatic Measuring Cup Placement (Cepha Block) was not completed. The analysis starts with the immediate issue—post-risk analysis was not planned or initiated—and progressively examines contributing causes such as unclear responsibility, weak cross-functional communication, absence of a defined SOP or timeline, and inadequate implementation of the risk-management system. The concerned functions for the risk assessment include Quality Assurance, Production, Quality Control, Engineering, and Store.
The root cause is concluded as insufficient implementation and tracking of the post-risk assessment process by QA. Corrective actions include establishing a defined procedure and timeline, assigning responsibilities, strengthening communication between departments, providing FMEA/risk-management training, conducting the pending post-risk analysis, and documenting residual risk. This approach helps ensure that equipment-related risks are formally reviewed and controlled.
5. Heat Map (FMEA) Post Risk Analysis for Automatic Vertical Round Bottle Sticker Labelling Machine Not Done:
The Post Risk Analysis for the Automatic Vertical Round Bottle Sticker Labelling Machine is required to confirm that risks identified during design, installation, operation, performance, and routine use remain adequately controlled. If the post-risk analysis is not completed, residual risks related to incorrect label placement, missing labels, label misalignment, wrong label application, sensor malfunction, speed variation, bottle handling, rejection-system failure, and operator error may remain unidentified or undocumented.
Non-completion may also result in inadequate evaluation of existing control measures and lack of evidence that the machine continues to operate within acceptable GMP requirements. The assessment should review potential failure modes using a suitable risk-management tool such as FMEA, evaluate Severity, Occurrence, and Detection, calculate the RPN, and identify any additional CAPA where required. Completion of the post-risk analysis helps ensure label accuracy, traceability, product identification, process reliability, patient safety, and regulatory compliance.
