FDA-Compliant Human Factors Engineering

Human Factors & FDA Usability Engineering

Designing medical devices that are safe, effective, and intuitive for intended users. We help you meet FDA's human factors requirements and reduce use-related risks before submission.

Why Human Factors Matters for FDA Submissions

Use errors are a leading cause of medical device recalls and patient harm. FDA's 2016 guidance requires documented evidence that devices minimize use errors.

The Risk of Ignoring Human Factors

  • FDA rejection or requests for additional information
  • Costly device recalls due to use errors
  • Patient harm and liability exposure
  • Delayed market entry and lost revenue
  • Post-market adverse event reports

Benefits of Proper HFE

  • Accelerated FDA approval with complete submissions
  • Reduced regulatory risk and fewer RFIs
  • Safer devices with intuitive interfaces
  • Lower post-market surveillance burden
  • Competitive advantage through user-centered design

Our Human Factors Engineering Process

A systematic approach aligned with FDA guidance to identify, analyze, and mitigate use-related risks

Step 1

User Research & Profiles

Define intended users, their characteristics, training levels, and use environments

Step 2

Use-Related Risk Analysis

Identify potential use errors and their severity through systematic hazard analysis

Step 3

Critical Task Identification

Determine which tasks could cause serious harm if performed incorrectly

Step 4

Formative Evaluations

Iterative testing with representative users to refine design and reduce use errors

Step 5

Design Modifications

Apply human factors principles to eliminate or mitigate identified risks

Step 6

HF Validation Testing

Summative testing demonstrating device can be used safely by intended users

FDA Human Factors Risk Categories

We help you determine the appropriate level of human factors documentation based on your device's risk profile

Category 1

Minimal Documentation

Device changes do not affect use-related hazards. Limited HF information required.

  • No new use errors introduced
  • No changes to user interface
  • Similar to predicate device
Category 2

Moderate Documentation

Changes affect hazards but do not add or impact critical tasks.

  • Modified user interface
  • No critical tasks affected
  • Formative testing may suffice
Category 3

Full HF Validation

Device has critical tasks or modifications that impact critical tasks.

  • Critical tasks present
  • Full summative testing required
  • Complete HF submission package
