Failure Mode and Effects Analysis (FMEA)

‍Failure Mode and Effects Analysis (FMEA) is an organized way to predict and analyze every possible way a product, process, or system could fail, before it actually happens.

The Failure Mode and Effects Analysis (FMEA) is a fundamental analytical tool used in quality management, particularly within the medical device industry, to proactively manage potential dangers and failures.

The goal of FMEA is to enable the early identification and mitigation of potential failure modes, ensuring that quality risks are managed proactively. FMEA focuses on answering the following core questions:

1. Failure Mode: What could possibly go wrong (the potential failure)?
2. Effect: What would the consequences be if it failed?
3. Analysis: What steps can we take now to prevent the failure or reduce its impact?

Overview of FMEA and Its Role

FMEA is considered a cornerstone of risk management in the medical device industry. It is one of the analytical methods, alongside tools like Fault Tree Analysis and Risk Assessment, used within the Quality Management System (QMS).

1. FMEA in Design Controls and Risk Management

FMEA is integral to fulfilling regulatory and quality standards, especially in the design and planning phases:

• Proactive Risk Mitigation: Identifying and mitigating issues early using FMEA can prevent costly design changes, production delays, and potential recalls later on.
• Design Validation and Risk Analysis: Design validation requirements specify that risk analysis must be included, where appropriate. FMEA is a technique used during this risk analysis to achieve compliance.
• Design Review: The Design Review process requires a failure mode analysis. This analysis should be used to proactively study what may happen to the functionality of the device in different environments.

2. Application Across the Product Lifecycle

FMEA is not a one-time activity; it must be implemented throughout the development and manufacturing phases:

• Process FMEA (pFMEA): When managing process risk, specifically in agreements with suppliers, manufacturers may require the supplier to demonstrate risk mitigation of process risk per ISO 14971 using tools like pFMEA (Process Failure Mode Effect Analysis). Similarly, FMEA tools are used in industries like pharmaceutical companies to identify and mitigate potential quality risks in manufacturing processes.
• Device System Hazards: FMEA is used as part of overall risk management strategies to address device system hazards. For example, in the context of certain microbial IVD tests, risk analysis and management strategies, such as Failure Modes Effects Analysis and/or Hazard Analysis and Critical Control Points summaries, must be developed to assess their impact on test performance.

3. Documentation Requirements

The results of the FMEA and related risk analysis activities must be formally documented as part of the QMS:

• Risk Control Measures: Documentation of FMEA and/or Hazard Analysis is required to demonstrate how risk control measures are implemented to address device system hazards.
• Design Controls: FMEA is part of the risk management activities performed as part of 21 CFR 820.30 Design Controls.
• Regulatory Submissions: For certain complex medical devices (e.g., automated test systems), the risk analysis and management strategies, such as Failure Modes Effects Analysis summaries, must be included in premarket notification submissions.
