beneficial in prioritizing risks based on their likelihood and impact. Document these assessments meticulously in a risk management file that addresses all potential hazards.

Step 2: Protocol Design for Validation Activities

The next step involves designing a validation protocol that aligns with both the URS and the risk assessment findings. The protocol should detail the methods to be used for the validation of the SCADA/PLC system’s data extraction processes. This document serves as a roadmap for the entire validation process and should include:

• Objective: Clearly state the purpose of the validation.
• Scope: Define which systems, processes, and data points will be validated.
• Responsibilities: Specify team members involved in the validation and their roles.
• Activities: Outline the procedures for conducting the validation, including testing methods, statistical analysis, and acceptance criteria.

Incorporate references to relevant guidelines, such as the FDA’s Process Validation Guidance, which emphasizes the importance of developing robust validation protocols.

Step 3: Executing the Qualification Stages (IQ, OQ, PQ)

With the protocol in place, initiation of the qualification stages—Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ)—is paramount. Each of these stages serves a specific purpose:

Installation Qualification (IQ)

In this phase, you verify that the SCADA/PLC systems are installed correctly and in accordance with the manufacturer’s specifications. This may involve documentation checks, equipment calibration, and ensuring that the environment meets specified standards. Maintain comprehensive records of all checks performed during this stage.

Operational Qualification (OQ)

OQ focuses on verifying that the SCADA/PLC functions as intended under normal operating conditions. Conduct tests on the automation system’s critical functions, such as data accuracy and response times. For example, test the robustness of data extraction processes against expected operational limits. Document any deviations and ensure corrective actions are taken.

Performance Qualification (PQ)

PQ is the final qualification stage where you demonstrate that the SCADA/PLC system consistently performs according to the URS under actual operating conditions. Take representative samples during operations to analyze data consistency and stability over time. Use statistical criteria to validate that data meets specified thresholds, ensuring ongoing compliance with regulatory expectations.

Step 4: Process Performance Qualification (PPQ)

The Process Performance Qualification (PPQ) phase transitions from validation to a more continuous verification approach. During this stage, gather data during multiple production cycles to validate the system further. Important tasks include:

• Batch Records: Review and compile batch records to confirm data consistency across multiple runs.
• Statistical Analysis: Employ statistical tools to validate the processes, including control charts and trend analyses, ensuring that outcomes are within control limits.
• Documentation: Meticulously document all findings and analyses for regulatory review. This should include raw data, summaries, and interpretative analyses.

Interactions with regulatory resources like Annex 15 will reinforce the necessity of adhering to these guidelines during PPQ. Further guidance is also available from bodies such as EMA’s process validation guidelines, ensuring compliance and best practices.

Step 5: Continued Process Verification (CPV)

CPV represents a commitment to ongoing verification of process performance and product quality throughout the life cycle of a product. After the successful validation of the SCADA/PLC data-pulling automation, establish systematic procedures for continued monitoring. Key components of CPV include:

• Data Analysis: Regularly analyze data collected through the SCADA/PLC systems to monitor for any trends, deviations, or anomalies.
• Change Control: Implement a robust change control system to manage any modifications to the SCADA/PLC setup and associated processes. Continuous documentation is essential for ensuring compliance.
• Periodic Review: Conduct quarterly reviews of the CPV data and processes to ensure that expectations are being met and that any necessary improvements are made.

The incorporation of data analytics into CPV can provide insights into process reliability and product consistency. Regular updates to the master validation plan, including changes from feedback during CPV, ensure that the approach remains dynamic and responsive to real-world operational factors.

Step 6: Revalidation and Scale Adjustments

As your operations evolve—be it through product variations, regulatory changes, or process optimizations—revalidation will be necessary. Revalidation is a critical step to ensure the system continues to perform effectively over time. Important tasks include:

• Identifying Triggers: Determine conditions that necessitate revalidation (e.g., significant changes to the process, new regulatory requirements).
• Documentation Reassessment: Review all related documentation and any changes implemented in the system to ascertain the need for revalidation.
• Repeat Qualification: Execute OQ and PQ again if substantial changes are made, ensuring the system aligns with prior validations.

Ongoing education on best practices in validation, documentation, and quality control remains crucial to maintaining compliance with established regulatory expectations. By integrating these steps effectively into your workflow, you can ensure robust data integrity and compliance with both FDA standards and EU GMP regulations.

Conclusion: Ensuring Compliance Through Validation Consulting

The automation of data pulling from SCADA/PLC systems plays a significant role in the contemporary pharmaceutical landscape, enhancing efficiency, reliability, and compliance in test method validation. By adhering to these structured validation steps, from URS and risk assessments through to continued process verification and revalidation, organizations within the pharmaceutical sector can uphold the highest quality assurance standards while meeting both FDA and EU regulatory expectations.

Furthermore, organizations should remain engaged with regulatory updates and guidance from official sources such as PIC/S and ISPE to ensure that their validation approaches are aligned with best practices and current trends. The commitment to quality and compliance—a cornerstone of organizational integrity—should drive ongoing training and development as automation technologies rapidly evolve.
