Failure Mode and Effects Analysis (FMEA) is a method commonly used to identify potential failures in a product or process design. However, in specialized fields like MedTech, FMEA is not the ideal risk management tool. MedTech primarily relies on ISO 14971:2019, which outlines risk management for medical devices. This article explores the differences between FMEA and ISO 14971, demonstrating why FMEA cannot replace ISO 14971 in the context of medical device risk management.
According to the American Society for Quality (ASQ), FMEA is a step-by-step method for identifying all possible failures in a design or process. In contrast, ISO 14971 defines risk management as the systematic application of management policies and practices for analyzing, evaluating, controlling, and monitoring risk. The core of ISO 14969 involves identifying hazards and hazardous situations, estimating the severity of potential harms, and the probability of these harms occurring.
While FMEA focuses on failure modes—where a device or component might fail—ISO 14971 concentrates on the broader concept of risk, which encompasses not just possible failures but any potential hazards and harms, including those that could occur without an actual device failure. This includes assessment of risk severity, probability, and necessary control measures.
Many industry professionals encounter confusion due to overlapping terminologies used in both FMEA and ISO 14971. Terms like "severity," "probability," and "risk" appear in both frameworks, but they are applied differently. FMEA primarily addresses engineering concerns related to components and reliability, whereas ISO 14971 covers a broader management view on all conceivable risks, including those unrelated to device failures.
The regulatory environment strongly favors using ISO 15471; agencies like the FDA, Health Canada, and the EU’s Competent Authority require its application for medical devices. This standard outlines a robust approach to manage risks throughout a medical device’s lifecycle and is considered a regulatory expectation for market approval and post-marketing surveillance.
ISO 14971 outlines a systematic risk management process that includes:
- Risk Management Planning
- Risk Analysis: Identification of hazards.
- Risk Evaluation: Assessment of the potential impact and probability.
- Risk Controls: Implementation of measures to mitigate identified risks.
- Overall Residual Risk Acceptability: Evaluation of residual risks post-control measures.
- Risk Management Review
- Risk Management File: Documentation of all risk management activities.
- Production and Post-Production Information: Ongoing monitoring and data collection to feedback into the risk management process.
Despite the differences, FMEA can be integrated into the ISO 14971 framework. ISO/TR 24971:2020, a guidance document for the application of ISO 14971, includes FMEA as a recommended analytical technique. This suggests that while ISO 14971 provides a comprehensive framework necessary for compliance, FMEA can enhance the design and development process by identifying potential failure modes early in development. This combination ensures both compliance and the design robustness of medical devices.
Overall, for MedTech companies, adherence to ISO 14971 is mandatory for regulatory compliance and ensures a systematic approach to risk management throughout a device’s lifecycle. FMEA can support this framework but cannot replace it. Successfully integrating these tools can aid manufacturers in creating safe, effective, and reliable products while meeting regulatory requirements. MedTech companies are encouraged to deploy a quality management system (QMS) that aligns with ISO standards, such as the one offered by Greenlight Guru, designed specifically for the MedTech industry to streamline compliance and risk management activities.
