Use related risk analyzer

Use-Related Risk Analyzer Skill

Purpose

The Use-Related Risk Analyzer Skill identifies and evaluates hazards associated with user interaction with medical devices, implementing IEC 62366-1 usability engineering methodology and supporting human factors risk analysis.

Capabilities

• Use scenario identification
• Task analysis decomposition
• Use error categorization (perception, cognition, action)
• Known use problems database search
• Risk mitigation strategy development
• Training vs. design solution recommendations
• User interface risk analysis
• Critical task identification
• Use error root cause analysis
• Usability test planning support
• IFU effectiveness evaluation

Usage Guidelines

When to Use

• Conducting use-related risk analysis
• Planning usability engineering activities
