Application of a risk assessment tool to define the extent of qualification/validation activities for analytical equipment and systems

Introduction:As part of a quality risk management system, decisions regarding the extent of qualification and validation for analytical instruments and software should be based on scientifically justified risk assessments.Defining the essential deliverables requires a comprehensive analysis of the analytical purpose and instrument complexity, facilitated by a risk assessment tool that integrates both technical and regulatory criteria.This approach prioritizes critical tests and ensures data reliability and consistency.Objectives: To demonstrate how a risk assessment tool can guide the definition of qualification and validation activities, identifying the essential deliverables necessary to ensure the proper use of analytical instruments.Methodology: A risk assessment tool was developed based on a review of guidelines, including ICH, PIC/S, USP <1058>, and GAMP 5.The assessment followed a three-step approach applied to 88 analytical instruments in a general inventory: (1) evaluating each instrument's relevance to Good Manufacturing Practice (GMP); (2) determining its complexity and assigning a corresponding risk level (A, B1, B2, B3, C1, C2, or C3); and (3) identifying the essential deliverables for each risk category to confirm fitness for intended use. Results:The tool classified the instruments into five GMP-related risk categories: 12 in B1 (very low, firmware with no integrated calculations), 12 in B2 (low, firmware with integrated calculations), 1 in B3 (medium, user-programmable), 6 in C1 (medium, non-configurable systems), and 57 in C2 (high, configurable systems).The required deliverables aligned with each category's criticality were defined: B1 -qualification required; B2 -qualification with calculation checks; B3 -qualification with verification of user-defined functions; C1 and C2 -validation of hardware/software, including critical configuration functionality where applicable. Conclusion:This work represents a significant advancement in applying a scientifically grounded, risk-based approach to defining the extent of qualification and validation for analytical instruments and systems.The proposed tool was easy to implement and provided an integrated assessment of hardware and software, enabling the prioritization of critical tests and the optimization of both time and resources in testing and documentation.
