Interview Questions for FDA Quality System Regulation 21 CFR Part 820

21 CFR Part 820, the FDA’s Quality System Regulation, establishes the minimum requirements for quality systems for medical device manufacturers. It’s designed to ensure that devices are safe and effective. The regulation covers a wide range of activities, from design and manufacturing to distribution and servicing. Key requirements include establishing and maintaining a quality system, design controls, production and process controls, nonconforming materials, corrective and preventive actions (CAPA), customer complaints, device tracking and identification, quality audits, and recordkeeping.

• Quality System: This forms the foundation, outlining the organization’s structure, responsibility, and procedures to ensure quality. Think of it as the overarching blueprint.
• Design Controls: This section emphasizes a rigorous process for design and development, including defining user needs, developing design outputs, and verifying and validating the design.
• Production and Process Controls: This ensures consistent manufacturing processes that meet pre-defined specifications. This includes proper validation of equipment and processes.
• Corrective and Preventive Actions (CAPA): This is a critical system for identifying, investigating, and correcting problems that affect product quality or compliance. It’s a proactive approach to avoid recurrence.
• Recordkeeping: Meticulous documentation is paramount, covering all aspects of the quality system. This is essential for demonstrating compliance to the FDA.

Think of it like building a house – each section represents a crucial step, from planning (quality system) to construction (production controls) and inspections (audits). Skipping a step or neglecting a vital element can compromise the entire structure.

A Quality Management System (QMS) is the backbone of compliance with 21 CFR Part 820. It’s a structured approach that encompasses all the processes, procedures, and resources needed to ensure consistent production of safe and effective medical devices. The QMS acts as a framework to implement and maintain the requirements outlined in the regulation. It provides a systematic way to manage all aspects of the device lifecycle, from initial design through post-market surveillance.

Think of a QMS as the operating manual for a medical device company’s quality efforts. It dictates how each department operates within the framework of 21 CFR Part 820. A robust QMS ensures consistent product quality, minimizes risks, streamlines processes, and facilitates compliance auditing.

For example, a well-defined QMS will include documented procedures for design control, process validation, CAPA, and complaint handling. These procedures serve as practical guides for employees, ensuring consistent application of regulatory requirements and preventing deviations from established standards.

Ensuring compliance with 21 CFR Part 820.22(a) regarding design controls requires a systematic approach that meticulously follows each stage of the design process. This isn’t a one-time effort but an ongoing process of verification and validation throughout the lifecycle of the product.

• Define User Needs: Clearly define the intended use and performance requirements of the device. This includes understanding the target users and their needs.
• Develop Design Output: Create detailed design specifications and drawings that meet the user needs. These should include materials, processes, and testing plans.
• Design Verification: Confirm that the design meets the predetermined specifications. This often involves testing and simulations.
• Design Validation: Demonstrate that the finished device meets its intended use and performs as expected in real-world conditions. This often includes clinical trials or field testing.
• Design Transfer: Ensure a smooth transition from the design phase to the manufacturing phase. This involves providing manufacturing with all necessary information and training.
• Design Changes: Establish a system for managing any changes to the design, ensuring that all changes are documented, reviewed, and approved.

Imagine designing a car. You would need to first determine what the car should do (user needs), then plan its parts (design output), test its engine (design verification), and finally test-drive it (design validation). Similarly, design controls ensure a similar structured approach is followed for a medical device.

A Corrective and Preventive Action (CAPA) system is a critical component of a quality system, designed to proactively identify, investigate, and correct problems that may affect product quality or compliance. It’s not just about reacting to problems, but also preventing them from happening in the future.

In the context of 21 CFR Part 820, a CAPA system is essential for addressing nonconformances, customer complaints, and audit findings. The goal is to prevent recurrence of similar issues. This system involves several key steps, such as investigation of the root cause, implementation of corrective actions to fix the immediate problem, and implementation of preventive actions to prevent similar problems from happening in the future.

For example, if a manufacturing defect is identified, the CAPA process involves investigating the root cause (e.g., faulty equipment, insufficient training), implementing corrective actions (e.g., repairing or replacing the equipment, providing retraining), and preventive actions (e.g., improving maintenance procedures, developing a more robust training program).

A robust CAPA system demonstrates to regulatory bodies the commitment to continuous improvement and product quality. It shows the FDA that the company is proactive in addressing potential risks.

Documentation is the cornerstone of compliance with 21 CFR Part 820. It’s the evidence that proves your company is meeting the regulatory requirements. Without proper documentation, it is impossible to demonstrate compliance to regulatory bodies like the FDA during an inspection. This extends to every aspect of the QMS, from design controls to CAPA.

Documentation serves several critical purposes:

• Evidence of Compliance: Documents serve as verifiable proof that all required processes and procedures have been followed.
• Traceability: Documents allow tracing the history of a product, from raw materials to final delivery. This is crucial for product recalls or investigations.
• Process Improvement: By reviewing records, companies can identify trends, problems, and areas for improvement.
• Training and Communication: Documents serve as training aids and improve communication among employees.

Imagine a detective solving a crime – they rely on evidence. Similarly, FDA inspectors rely on documentation to verify a company’s compliance with 21 CFR Part 820. Incomplete or inaccurate records can lead to citations, warnings, or even product recalls.

My experience with conducting internal audits according to 21 CFR Part 820 encompasses planning, execution, reporting, and follow-up. I have led numerous internal audits across various medical device companies. My approach involves a risk-based methodology, focusing on areas of highest risk and potential for noncompliance.

The process typically starts with developing an audit plan that outlines the scope, objectives, and timeline of the audit. This plan includes the specific areas to be audited, the procedures to be reviewed, and the personnel involved. During the audit, I gather evidence by reviewing documents, observing processes, and interviewing employees. Following the audit, a comprehensive report is prepared, detailing any findings, including observations, nonconformances, and recommendations for improvement.

I am proficient in using audit management software to track findings, manage corrective actions, and ensure timely closure of audit recommendations. I am also well-versed in various audit methodologies and techniques, including process mapping and sampling techniques, to optimize the effectiveness and efficiency of the audit process.

Handling nonconformances identified during internal audits is a crucial step in maintaining compliance with 21 CFR Part 820. My approach involves a systematic process that ensures effective corrective actions and prevents recurrence.

• Immediate Response: Upon identification of a nonconformance, the immediate priority is to contain the issue and prevent further impacts.
• Root Cause Analysis: A thorough investigation is conducted to determine the root cause(s) of the nonconformance, rather than just addressing the symptoms.
• Corrective Action Plan: A corrective action plan is developed and documented to address the immediate nonconformance. This includes specific steps, responsible parties, timelines, and verification methods.
• Preventive Action Plan: In parallel, preventive actions are implemented to prevent similar issues from recurring. This might include process improvements, employee training, or equipment upgrades.
• Verification and Validation: Once implemented, the corrective and preventive actions are verified and validated to ensure their effectiveness.
• Documentation: The entire process, from identification of the nonconformance to the final verification of corrective actions, is thoroughly documented.

This structured approach ensures that nonconformances are not only addressed immediately but also prevent future occurrences. This reduces risks and demonstrates a commitment to continuous improvement, all key aspects of maintaining compliance.

Preventative actions (PAs) and corrective actions (CAs) are both crucial for maintaining compliance with 21 CFR Part 820, but they address different stages of quality issues. Think of it like this: PAs are about preventing problems before they happen, while CAs are about fixing problems after they’ve occurred.

Preventative Actions (PAs): These are proactive measures designed to eliminate the potential for nonconformities. They address potential problems identified through risk assessments, audits, process capability studies, or even customer feedback, before they lead to actual product defects. For example, if a risk assessment reveals a potential for contamination during a particular manufacturing step, a PA might involve implementing improved cleaning procedures, installing new equipment, or enhancing operator training.

Corrective Actions (CAs): These are reactive measures taken to address actual nonconformities that have already occurred. They aim to correct the immediate problem, identify its root cause, and prevent recurrence. Imagine a batch of product fails a quality test. A CA would involve isolating the affected batch, investigating why it failed (e.g., faulty raw materials, equipment malfunction), correcting the issue, and preventing it from happening again (e.g., implementing stricter quality checks, replacing faulty equipment).

• Key Differences Summarized:
• PA: Proactive, addresses potential problems, prevents nonconformities.
• CA: Reactive, addresses existing nonconformities, corrects problems and prevents recurrence.

Both PAs and CAs require thorough documentation, including the problem description, root cause analysis, corrective actions taken, and effectiveness verification. A well-defined CAPA (Corrective and Preventative Action) system is essential for any medical device company to effectively manage both.

Ensuring traceability of materials and components is paramount in medical device manufacturing. It allows you to track the entire history of a product, from raw material sourcing to final delivery, enabling quick identification and remediation of any quality issues. This is achieved through a robust system of identification and record-keeping.

This usually involves a unique identification number (UID) assigned to each component or batch of materials at every stage of the process. This UID is then tracked through a system of documentation, often including:

• Supplier Certificates of Analysis (CoA): Documenting the quality of incoming raw materials.
• Material Receiving Logs: Recording the receipt and identification of materials.
• Batch Records: Detailed records of each manufacturing batch, linking materials and components used.
• Device History Records (DHR): Comprehensive history of the device, including all materials and components.
• Databases and ERP Systems: Digital platforms for streamlined tracking and reporting.

For example, a specific lot of silicone used in a catheter would have a UID that’s traceable back to the silicone supplier, through the manufacturing process, and ultimately to the final product. If a problem arises with that catheter, tracing the UID allows quick identification of the potentially faulty silicone lot and facilitates any necessary recall or corrective action.

Managing change control under 21 CFR Part 820 is critical for maintaining product quality and regulatory compliance. Any change impacting the design, manufacturing process, or quality system needs rigorous control to ensure that changes don’t negatively affect the safety and effectiveness of the product.

My experience involves establishing and maintaining a formal change control process, encompassing these key steps:

• Change Request Submission: A formal request detailing the proposed change, its rationale, and potential impact.
• Change Evaluation: A team assesses the risk associated with the change, considering its impact on design, manufacturing, and quality.
• Change Approval: Authorized personnel review and approve the change based on the risk assessment.
• Change Implementation: The change is implemented following the approved plan.
• Change Verification: The implemented change is verified to ensure it meets specifications and doesn’t introduce new problems.
• Documentation: Meticulous documentation is maintained throughout the entire process.

I’ve worked with various change control systems, both paper-based and electronic. In one instance, we implemented a new automated packaging system. Our change control process ensured that the system was properly validated, operator training was conducted, and all documentation was updated to reflect the change before implementation. This ensured a smooth transition and minimized the risk of nonconformities.

Validation is a critical aspect of 21 CFR Part 820, ensuring that processes, equipment, and systems consistently perform as intended. My experience spans various validation activities, including process validation, equipment qualification, and software validation.

Process Validation: This involves demonstrating that a manufacturing process consistently produces a product meeting predetermined specifications. This typically includes defining acceptance criteria, performing validation runs, and analyzing the data to confirm process capability. For example, I’ve been involved in validating sterilization processes for medical devices, ensuring the effectiveness of the process in eliminating microorganisms.

Equipment Qualification: This ensures that equipment is suitable for its intended use. It involves activities such as Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ). I’ve worked on qualifying various pieces of equipment, such as autoclaves, cleanrooms, and analytical instruments.

Software Validation: This ensures that software used in manufacturing or quality control performs as intended. This includes risk analysis, design verification, and testing. I have experience validating software used for data acquisition, process control, and quality management systems.

In all validation activities, thorough documentation is crucial, including protocols, reports, and any deviations addressed.

Handling customer complaints effectively is vital for maintaining product quality and customer satisfaction. The process under 21 CFR Part 820 typically involves these steps:

• Complaint Receipt and Recording: All complaints are promptly received, documented, and assigned a unique identification number.
• Complaint Evaluation: The complaint is evaluated to determine its nature and severity, including any potential risk to patient safety.
• Investigation: A thorough investigation is conducted to determine the root cause of the complaint. This may involve reviewing manufacturing records, interviewing personnel, and testing the product.
• Corrective Action: Corrective actions are implemented to address the root cause of the complaint and prevent recurrence. This may involve modifying manufacturing processes, improving quality control procedures, or issuing a field corrective action.
• Response to Customer: The customer is informed of the investigation findings, corrective actions taken, and any necessary follow-up actions.
• Documentation: All aspects of the complaint handling process are meticulously documented.

For example, if a customer reports a malfunction in a device, we would immediately investigate, identify the root cause (e.g., defective component), implement corrective actions to prevent future occurrences, and provide a timely response to the customer outlining the steps taken. All this is documented in detail, contributing to our CAPA system.

Investigating a potential product nonconformity requires a systematic and thorough approach. The goal is to identify the root cause, implement corrective actions, and prevent recurrence. My approach usually follows these steps:

• Initial Assessment: Gather information about the nonconformity, including the affected product(s), the nature of the nonconformity, and any associated complaints.
• Data Collection: Collect relevant data, including manufacturing records, test results, and any other relevant documentation.
• Root Cause Analysis: Use appropriate tools, such as 5 Whys, fishbone diagrams, or fault tree analysis, to identify the root cause(s) of the nonconformity.
• Corrective Actions: Develop and implement corrective actions to address the identified root cause(s).
• Verification: Verify the effectiveness of the implemented corrective actions to ensure that the problem is resolved and is unlikely to recur.
• Documentation: Maintain detailed records of the investigation, including the nonconformity description, root cause analysis, corrective actions, and verification results.

For instance, if a batch of products fails a sterility test, I would analyze the manufacturing process, examine the sterilization equipment logs, and review the raw materials used to pinpoint the cause. This could range from equipment malfunction to contamination during manufacturing. Once identified, corrective and preventative actions would be implemented to rectify the issue and prevent future failures.

Supplier quality management is integral to 21 CFR Part 820, as the quality of incoming materials and components directly impacts the final product’s quality and safety. My experience encompasses establishing and maintaining a robust supplier management system to ensure that our suppliers consistently meet our quality requirements.

This involves:

• Supplier Selection and Qualification: Rigorous evaluation of potential suppliers to assess their capability and compliance with regulatory requirements. This includes audits and review of their quality systems.
• Supplier Monitoring: Ongoing monitoring of supplier performance through regular audits, review of quality metrics, and evaluation of CAPA effectiveness.
• Incoming Inspection: Inspecting incoming materials and components to ensure they meet specifications and quality standards.
• Supplier Corrective Actions: Working with suppliers to address and resolve any quality issues.
• Documentation: Maintaining detailed records of supplier performance, inspections, and corrective actions.

For example, we might perform audits of our raw material suppliers to assess their GMP (Good Manufacturing Practices) compliance. If a supplier fails to meet our standards, we would work with them to develop a Corrective Action Plan. This collaborative approach helps ensure consistent supply of high-quality materials, minimizing the risk of issues impacting our products.

21 CFR Part 820, the FDA’s Quality System Regulation for medical devices, mandates meticulous record-keeping. These records aren’t just paperwork; they’re the lifeblood of demonstrating compliance and ensuring product safety. They document every step, from design and development to production, distribution, and post-market surveillance. The regulation specifies what records must be maintained, how long they must be retained, and the requirements for their accuracy and accessibility.

• Design Controls (820.30): Records detailing design inputs, outputs, design reviews, verification and validation activities, and design changes are crucial.
• Production and Process Controls (820.40): This includes records of manufacturing processes, equipment calibration, materials testing, and production records (batch records).
• Corrective and Preventive Actions (CAPA) (820.100): Detailed documentation of deviations, nonconformances, investigations, root cause analyses, and corrective actions implemented is paramount.
• Quality Audits (820.22): Reports from internal and external audits detailing findings and corrective actions.
• Supplier Control (820.50): Records demonstrating the management and control of suppliers, ensuring their processes meet the required quality standards.

Failing to maintain accurate and complete records can lead to significant consequences, including warning letters, recalls, and even injunctions from the FDA. The level of detail required depends on the classification and risk of the medical device.

Ensuring the accuracy and integrity of quality records is paramount. It’s not just about filling out forms; it’s about establishing a robust system that prevents errors and ensures traceability. Think of it like building a sturdy house – you need a solid foundation.

• Standard Operating Procedures (SOPs): Detailed SOPs dictate exactly how records should be created, handled, stored, and retrieved. Everyone involved follows the same procedure, reducing variation and errors.
• Electronic Record-Keeping Systems: Secure, validated electronic systems offer many advantages, including audit trails, version control, and easier accessibility. Proper validation and security measures are essential.
• Training and Accountability: Comprehensive training ensures that personnel understand record-keeping requirements and their responsibilities. Clear roles and responsibilities prevent confusion and accountability is vital.
• Regular Audits and Reviews: Internal and external audits verify that the record-keeping system is functioning as intended. Regular reviews can identify areas for improvement.
• Data Integrity Checks: Regular checks and balances such as data reconciliation and comparisons can uncover anomalies and prevent data corruption.

For example, imagine a batch record with a missing signature. A robust system will flag this immediately, preventing potential issues. If the discrepancy is found later, it can be difficult and time consuming to trace the cause of the missing signature.

My experience in managing quality records spans over [Number] years, encompassing roles in [mention relevant roles]. I’ve been directly involved in establishing and maintaining compliant record-keeping systems for medical devices, ranging from Class I to Class III. This includes:

• Implementation of electronic document management systems (EDMS): I’ve led projects to implement and validate EDMS systems, ensuring data integrity and regulatory compliance. This involved selecting the right software, developing SOPs, training personnel, and managing the transition.
• Archiving and Retrieval of Records: I’ve developed and implemented procedures for securely archiving records, both physical and electronic, ensuring easy retrieval when needed. This includes managing long-term storage, version control, and data backup.
• Record Retention Policies: I’ve developed and implemented policies compliant with 21 CFR Part 820 and other relevant regulations, determining appropriate retention periods for various types of records.
• Responding to Audits and Inspections: I’ve directly supported FDA and Notified Body inspections, providing evidence of compliance and resolving any discrepancies.

In one instance, I streamlined our CAPA process by implementing a new electronic system, reducing the time to closure by 40%. This improved efficiency and transparency. The result was a more efficient and less labor-intensive system for tracking and managing CAPAs.

Root cause analysis (RCA) is critical in identifying the underlying reasons for deviations, nonconformances, and other quality issues. It’s not about assigning blame, but about understanding the ‘why’ behind the problem to prevent recurrence. I am experienced in several RCA methodologies, including:

• 5 Whys: A simple yet effective method involving repeatedly asking “why” to drill down to the root cause. This is especially useful for simple issues.
• Fishbone Diagram (Ishikawa): A visual tool to brainstorm and categorize potential causes, helping to identify root causes systematically.
• Fault Tree Analysis (FTA): A more complex method used to identify potential failures and their contributing factors, often used for complex systems or processes.
• Failure Mode and Effects Analysis (FMEA): A proactive approach to identify potential failures in a system and assess their severity and probability, enabling preventative measures.

In a recent project, we used a combination of 5 Whys and Fishbone diagrams to investigate a recurring manufacturing defect. By systematically identifying the root causes (worn tooling and inadequate operator training), we implemented corrective actions to prevent recurrence. The result was a significant reduction in product defects, improving product quality and reducing waste.

Ensuring compliance with 21 CFR Part 820 in a manufacturing environment requires a holistic approach, encompassing all aspects of the quality system. It’s not a checklist but a culture of quality embedded in every process.

I’ve developed and implemented comprehensive training programs for various roles within medical device manufacturing. For example, I created interactive online modules for operators, focusing on Good Manufacturing Practices (GMPs) and record-keeping. The modules were followed by hands-on training and regular refresher courses. This ensured consistent understanding of procedures and compliance with 21 CFR Part 820.

Risk management in 21 CFR Part 820 is a proactive approach to identifying, analyzing, evaluating, and controlling risks throughout the entire product lifecycle. It’s not just about reacting to problems; it’s about preventing them. The FDA expects manufacturers to have a comprehensive system in place to minimize risks that could lead to unsafe or ineffective medical devices.

This involves several key elements:

• Hazard Analysis: Identifying potential hazards associated with the design, manufacture, and use of the device.
• Risk Assessment: Evaluating the likelihood and severity of each hazard.
• Risk Control: Implementing measures to mitigate or eliminate identified risks. These controls might involve design changes, process improvements, or additional testing.
• Risk Monitoring: Continuously evaluating the effectiveness of implemented controls and making adjustments as needed. This often involves post-market surveillance.

For example, imagine a company manufacturing infusion pumps. A risk assessment might identify the potential hazard of inaccurate drug delivery. Risk control measures could include rigorous testing of the pump’s accuracy, redundant safety mechanisms (e.g., alarm systems), and thorough operator training. Ongoing monitoring would track field performance and any reported incidents.

Ensuring product labeling complies with 21 CFR Part 820 is crucial for patient safety and regulatory compliance. Labels must accurately reflect the device’s intended use, provide necessary warnings and precautions, and meet specific FDA formatting requirements.

My approach involves:

• Adherence to FDA Regulations: Ensuring the label complies with all relevant FDA regulations, including font sizes, warning statements, and required information like lot numbers and expiration dates.
• Label Artwork Review: Verifying that the label’s design is clear, unambiguous, and easy to read. This includes checking for any potential errors in printing or layout.
• Controlled Document Management: Maintaining a controlled system for creating, reviewing, approving, and distributing labels. Revision control is paramount to avoid unintended use of outdated labels.
• Post-Market Surveillance: Monitoring for any issues related to labeling in the field.

Imagine a scenario where the instructions for use on a surgical instrument are unclear. This could lead to improper use and potentially serious complications. A rigorous labeling process helps prevent such scenarios.

Handling deviations and out-of-specification (OOS) results requires a systematic and thorough approach. It’s essential to investigate the root cause, document findings, and implement corrective and preventive actions (CAPA) to prevent recurrence.

My experience involves:

• Immediate Investigation: Initiating an investigation as soon as a deviation or OOS result is identified. This involves collecting all relevant data and information.
• Root Cause Analysis: Determining the underlying cause(s) of the deviation or OOS result. Tools like Fishbone diagrams or 5 Whys can be very useful.
• Corrective and Preventive Actions (CAPA): Implementing actions to correct the immediate issue and prevent similar occurrences in the future. This might involve equipment calibration, process improvements, or employee training.
• Documentation: Maintaining detailed records of the entire process, from the initial identification of the deviation to the implementation and verification of corrective actions. This documentation is crucial for audits.
• Management Review: Regular review of deviation and OOS reports to track trends and identify systemic issues.

For example, if a batch of sterile syringes fails a sterility test, a thorough investigation might reveal a problem with the sterilization cycle. CAPA might involve recalibrating the sterilizer, retraining personnel, and improving monitoring procedures.

Process validation is a critical element of 21 CFR Part 820, demonstrating that manufacturing processes consistently produce products that meet predetermined specifications. My experience encompasses all phases of process validation:

• Process Design: Participating in the design and development of manufacturing processes, ensuring they are robust and capable of consistently producing high-quality products.
• Validation Planning: Developing comprehensive validation plans that define the scope, methodology, and acceptance criteria for validation activities.

• Data Analysis: Analyzing validation data to demonstrate that the process consistently meets predefined specifications. Statistical methods are often employed.
• Report Writing: Preparing detailed validation reports that document the entire process, including results, conclusions, and any necessary deviations.
• Deviation Management: Addressing and documenting any deviations from the validation plan.

For instance, validating a sterilization process might involve demonstrating that the process consistently achieves sterility levels meeting FDA requirements. This includes monitoring temperature, pressure, and other critical parameters.

Quality audits are essential for maintaining compliance with 21 CFR Part 820. They provide an independent assessment of the quality system’s effectiveness and identify areas for improvement. They can be internal or external.

Internal audits are conducted by company personnel to assess compliance with internal procedures and regulations. External audits are conducted by regulatory agencies or independent third parties.

My experience includes:

• Audit Planning: Developing audit plans that define the scope, objectives, and methodology of the audit.
• Audit Execution: Conducting audits according to established procedures, collecting evidence, and documenting findings.
• Report Writing: Preparing comprehensive audit reports that summarize findings, including observations, non-conformances, and recommendations for corrective actions.
• Follow-up: Following up on corrective actions to ensure their effectiveness.
• Continuous Improvement: Utilizing audit findings to improve the quality system.

Regular audits help ensure that the quality system is working as intended and identify any potential weaknesses before they lead to product non-compliance or regulatory issues.

Handling discrepancies during document reviews requires a methodical approach to ensure accuracy and regulatory compliance. Discrepancies can range from minor typographical errors to significant deviations from approved procedures.

My approach involves:

• Clear Documentation of Discrepancies: Documenting each discrepancy clearly and concisely, including the location, nature, and potential impact.
• Immediate Communication: Communicating the discrepancy to the responsible individual or team promptly.
• Investigation and Root Cause Analysis: Investigating the root cause of the discrepancy to determine if it’s an isolated incident or indicative of a larger problem.
• Corrective Action: Implementing appropriate corrective actions to resolve the discrepancy and prevent recurrence. This may involve correcting the document, revising procedures, or providing additional training.
• Verification of Corrective Action: Verifying that the corrective action has effectively addressed the discrepancy.
• Change Control: Implementing changes through formal change control processes to ensure traceability and prevent unintended consequences.

For instance, if a document contains an incorrect specification for a critical material, immediate corrective action would be required to update the document and verify that no affected products have been manufactured using the incorrect specification.
