How to Conduct an FMEA Analysis
Step-by-step guide to performing Failure Mode and Effects Analysis for medical devices
ISO 14971:2019 Total Product Life Cycle Risk Management
Universal risk management framework for medical devices across design, verification, and market life
Risk Analysis
Identify intended use, foreseeable misuses, and characteristics related to safety. Enumerate known and foreseeable hazards leading to hazardous situations.
Required Process Activities
- Document intended use and reasonably foreseeable misuse (Clause 5.2)
- Identify hazards (biological, chemical, electrical, software, thermal, optical) (Clause 5.3)
- Estimate risk for each hazardous situation by evaluating Severity (S) and Probability (P) (Clause 5.5)

Overview
What is FMEA?
Failure Mode and Effects Analysis (FMEA) is a systematic method for identifying and preventing product and process failures. For medical devices, FMEA is required by ISO 14971 for risk management and is essential for regulatory compliance.
Why Use FMEA?
- Identify risks before they cause harm
- Prioritize risk mitigation efforts
- Meet ISO 14971 requirements
- Support regulatory submissions
Prerequisites
- Understanding of ISO 14971 risk management principles
- Access to device design specifications
- Cross-functional team availability
- FMEA template or worksheet

Planning & Team Setup
Establish the foundation for your FMEA analysis
1. Define Scope
Clearly define what you're analyzing: a device, component, process, or system. For medical devices, FMEA typically covers design (DFMEA) and process (PFMEA).
Example: "Class 4 surgical laser system - DFMEA for power control subsystem"
2. Assemble Cross-Functional Team
Include representatives from engineering, quality, regulatory, clinical, and manufacturing. Each brings unique perspective on potential failures.
- Design engineers (understand device function)
- Quality engineers (understand risk management)
- Regulatory affairs (understand compliance requirements)
- Clinical specialists (understand use scenarios)
- Manufacturing engineers (understand production risks)
3. Gather Information
Collect relevant documentation before starting:
- Design specifications and requirements
- Previous FMEAs (if available)
- Historical failure data and complaints
- Similar device adverse events
- Regulatory requirements (ISO 14971, ISO 13485)
