# 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
- Designing user interfaces
- Evaluating training effectiveness

### Prerequisites
- User profiles defined
- Use environments characterized
- Intended use documented
- Use scenarios identified

### Best Practices
- Integrate with ISO 14971 risk management
- Prioritize inherently safe design
- Test with representative users
- Validate critical tasks

## Process Integration

This skill integrates with the following processes:
- Human Factors Engineering and Usability
- Medical Device Risk Management (ISO 14971)
- Verification and Validation Test Planning
- Design Control Process Implementation

## Dependencies

- IEC 62366-1 standard
- FDA Human Factors guidance
- AAMI HE75 guidelines
- Known problems databases
- User interface standards

## Configuration

```yaml
use-related-risk-analyzer:
  user-profiles:
    - healthcare-professional
    - patient
    - caregiver
    - lay-user
  error-categories:

Overview

This skill performs use-related risk analysis to identify hazards tied to user interaction with medical devices, following IEC 62366-1 usability engineering principles. It produces task decompositions, catalogs use errors, and recommends design or training mitigations to reduce user-caused risks. The outputs are aimed to integrate with ISO 14971 risk management and verification planning.

How this skill works

The skill inspects defined user profiles, use environments, and documented use scenarios to decompose tasks and identify critical tasks. It classifies potential use errors into perception, cognition, and action categories, searches known-problem databases, and generates mitigation options prioritized toward design fixes. It also produces artifacts for usability testing, IFU evaluation, and traces into risk management.

When to use it

  • During early-stage usability engineering and device design reviews
  • When planning human factors and usability test protocols
  • While performing use-related risk analysis tied to ISO 14971
  • Before finalizing training, labeling, or Instructions for Use (IFU) content
  • To evaluate known use problems or post-market use issues

Best practices

  • Define representative user profiles and realistic use environments before analysis
  • Prioritize inherently safe design changes over training where possible
  • Validate identified critical tasks with representative users in realistic conditions
  • Integrate findings into the overall risk management file and V&V plans
  • Document assumptions, residual risks, and rationale for training vs. design solutions

Example use cases

  • Analyze a home-use infusion pump to identify perception and action errors and propose UI redesigns
  • Decompose workflow for a portable diagnostic device to find critical tasks for verification
  • Assess IFU clarity and recommend wording or layout changes to reduce cognitive errors
  • Evaluate whether reported field use problems indicate a need for design change or updated training
  • Generate a usability test plan focused on validated critical tasks for regulatory submission

FAQ

What inputs are required to run an effective analysis?

User profiles, detailed intended use and use scenarios, and characterized use environments are required to produce reliable task analyses and risk recommendations.

Does the skill replace ISO 14971 risk management?

No. It complements ISO 14971 by focusing on use-related hazards and providing artifacts and mitigations that should be integrated into the overall risk management process.
