Risk management in the medical device industry isn’t optional – it’s literally life or death. If you’re developing medical devices, you need to identify, assess, and mitigate risks throughout your entire product lifecycle. Patient safety depends on it.Watch this step-by-step guide to implementing FMEA for medical device risk management.
Last week I covered hazard analysis based on ISO 14971. This week, we’re diving into FMEA – one of the most powerful methodologies for medical device risk management, especially when software is involved.
FMEA stands for Failure Modes and Effects Analysis. It’s a detailed, bottom-up risk analysis approach that identifies potential failure modes in components, processes, or software. Unlike hazard analysis, FMEA gets granular – examining exactly how things can fail and what happens when they do.
Here’s what makes FMEA different from hazard analysis:
FMEA typically complements hazard analysis. While hazard analysis is a top-down, qualitative method that addresses system-level hazards, FMEA provides the granular, quantitative analysis needed for targeted risk mitigation.
Let me break down the FMEA process into manageable steps:
Start by clearly defining what you’re analyzing – the system, subsystem, or component under review. Consider the entire product lifecycle from design to disposal.
Review your device specifications, design documents, and regulatory requirements. You need crystal-clear understanding of:
Assemble experts from engineering, quality, regulatory affairs, and clinical departments. Don’t just assign responsibility – give your risk owners the authority and resources to actually manage the risks they own.
Establish clear communication processes for effective collaboration throughout the FMEA analysis.
Break your medical device into its functions and sub-functions. Identify performance requirements for each function, including regulatory, user, and safety needs.
Create functional diagrams to visualize the system and identify critical or life-supporting functions. This visual approach helps ensure you don’t miss anything important.
For every identified function or software component, brainstorm all possible failure modes. Consider how each function or component might fail.
Use:
Don’t skip this step – overlooked failure modes become real-world problems.
Evaluate how each failure mode impacts:
Look at both local effects (within the device) and broader system-level effects. Include clinical perspective when identifying potential patient or user harms.
Dig into the root causes that could trigger each failure mode. Explore potential errors in:
Understanding the “why” behind failures is essential for effective mitigation.
Here’s where FMEA gets quantitative. Assign scores for severity, occurrence, and detectability for each failure mode using your predefined ranking system.
Calculate the Risk Prioritization Number (RPN) by multiplying these three scores:
RPN = Severity × Occurrence × Detectability
The RPN gives you a numerical value to prioritize which risks need immediate attention.
For unacceptable risks, propose and document appropriate risk control measures. These usually include:
Focus on reducing probability of occurrence and improving detectability of failures.
After implementing risk controls, recalculate the RPN to verify that residual risk falls within acceptable limits as defined in your risk management plan.
Confirm that all mitigations have been properly verified for effectiveness. This step is critical – mitigation without verification is just wishful thinking.
Document all steps, findings, and decisions in your FMEA worksheet. Maintain it as a living document that reflects:
Everything must be documented for regulatory compliance and audit readiness.
These approaches are complementary:
The main connection point is at the cause level – certain failure modes can result in hazardous situations, and hazards can be caused by specific failure modes.
Let’s walk through a practical example. Imagine we’re developing a smartphone app that records glucose levels, insulin doses, and meal logs for diabetes management. The app syncs with cloud storage and shares patient data with healthcare providers.
We need to analyze how software security failures in data handling and access control could compromise both app functionality and patient confidentiality.
Key failure modes might include:
System effects could be:
Root causes might include:
After scoring severity, occurrence, and detectability, we’d implement mitigation actions like:
Tools matter. Here’s how you can conduct FMEA in Jira using the Risk Manager Plus from SoftComply – one of the most configurable risk management apps available today.
The process starts with defining your risk model based on the three risk characteristics: severity, probability of occurrence, and detectability. Risk Manager Plus provides templates you can customize or you can create your risk model from scratch.
Once your risk model is set up, you can use the FMEA risk register (from template) and customize it for your specific needs. The app supports:

Remember, ISO 14971 is the international standard for medical device risk management, and compliance is required by regulatory bodies. Your FMEA documentation becomes part of your overall risk management file.
Everything needs to be documented:
The documentation isn’t just for compliance – it’s your roadmap for maintaining device safety throughout its lifecycle.
FMEA isn’t just another regulatory checkbox. It’s a systematic way to think through how your device might fail and what you can do about it before those failures reach patients.
The quantitative nature of FMEA makes it particularly valuable for prioritizing your risk mitigation efforts. When you have limited resources (and who doesn’t?), the RPN scores help you focus on the highest-impact risks first.
Used together with Hazard Analysis, FMEA provides comprehensive risk coverage – from high-level system hazards down to specific component failure modes. This dual approach gives you confidence that you’ve identified and managed the risks that matter most.
The key is treating FMEA as a living process, not a one-time activity. As your device evolves through design changes, manufacturing improvements, and post-market feedback, your FMEA should evolve too.
Patient safety depends on getting this right. Take the time to do thorough FMEA analysis – your users’ lives may literally depend on it.
