Post Risk Analysis For Automatic Measuring Cup Replacement

1. Brief Description:

The Post Risk Analysis for Automatic Measuring Cup Placement is a Quality Assurance FMEA report prepared for equipment used in the Cepha Block for powder oral dosage manufacturing. The document evaluates risks associated with equipment design, installation, operation, performance, cleaning, safety, documentation, calibration, utilities, and qualification activities. Its objective is to identify potential failure modes, assess their effects and causes, and rank risks using Severity, Occurrence, and Detection scores to calculate the Risk Priority Number (RPN). Risks are categorized as Critical, Major, Moderate, or Minor, with CAPA required for RPN values above 25. The assessment reviews issues such as inadequate DQ/IQ/OQ documentation, missing reference documents, MOC verification, calibration checks, motor operation, safety features, cleaning, change control, and operating speed. Existing controls, SOPs, trained personnel, and qualification checks are used to reduce risk and confirm the equipment remains capable of supporting product quality and operator safety throughout its intended operational lifecycle.

2. Flow Diagram:

The flow diagram presents the Post Risk Analysis process for Automatic Measuring Cup Placement using the FMEA methodology. It begins with defining the equipment and assessment scope, followed by collection of background information related to design, installation, operation, performance, and safety. Potential failure modes are then identified and their possible effects and causes are evaluated. Each risk is rated for Severity (S), Occurrence (O), and Detection (D), and the Risk Priority Number (RPN = S × O × D) is calculated. Risks are classified as Critical, Major, Moderate, or Minor according to predefined RPN criteria. Existing controls such as SOPs, qualification checks, training, cleaning, and safety measures are reviewed. Where necessary, CAPA is implemented, followed by residual-risk reassessment, documentation of risk-control measures, preparation of the summary and conclusion, and final approval to confirm that identified risks are adequately controlled.

3. Brainstorming:

Post Risk Analysis for Automatic Measuring Cup Replacement – Not Done indicates that the formal FMEA-based evaluation has not yet been completed after implementation or replacement of the measuring cup system. The source document defines the purpose of post-risk assessment as evaluating risks related to the equipment’s design, installation, operation, performance, and safety using the FMEA methodology.

Until the assessment is performed, potential failure modes such as inadequate qualification documents, incorrect cup placement, calibration issues, cleaning deficiencies, safety concerns, operating-speed problems, and equipment-performance failures may not be systematically evaluated. The FMEA should assign Severity, Occurrence, and Detection ratings and calculate the Risk Priority Number (RPN) to determine whether additional controls or CAPA are required. Completion of the post-risk analysis is important to confirm that existing controls are effective and that residual risks to product quality, equipment performance, and operator safety are acceptable.

4. 5 Why Analysis:

The 5 Why Analysis for Post Risk Analysis for Automatic Measuring Cup Replacement – Not Done is used to identify the underlying reason why the required post-risk assessment was not completed after equipment replacement. The analysis starts with the immediate problem: the post-risk assessment was not planned or initiated. Further questioning identifies poor communication of the requirement, unclear responsibility for initiating and tracking the assessment, inadequate implementation or follow-up of the applicable SOP, and insufficient awareness, training, and management monitoring. The analysis therefore indicates that the main root cause is a weak system for SOP implementation, responsibility assignment, training, and follow-up of post-risk assessment activities. This is relevant because the source risk-management document requires post-assessment using FMEA for the Automatic Measuring Cup Placement equipment and defines responsibilities involving Quality Assurance, Engineering, Production, Quality Control, and Store. Addressing the root cause can help ensure timely risk reassessment and documented control of residual risks.

5. Heat Map:

The Heat Map for Post Risk Analysis for Automatic Measuring Cup Replacement – Not Done visually represents the potential risk associated with failure to perform the required post-risk assessment. The diagram uses Severity, Occurrence, and Detection principles from the FMEA methodology to prioritize risk and support decision-making. The example shown highlights a Moderate Risk, indicating that additional control measures and documented assessment should be planned. According to the source document, risks with an RPN of 26–50 are classified as Moderate and require CAPA, while higher RPN values fall into Major or Critical categories. The heat map emphasizes that leaving the post-risk analysis incomplete may allow potential equipment-performance, product-quality, safety, qualification, or compliance risks to remain insufficiently evaluated. The highlighted score in the diagram is illustrative; actual Severity, Occurrence, and Detection ratings should be assigned by the authorized cross-functional team based on documented evidence and existing controls.
