Why You Need to Start Your Risk Hazard Analysis Early in Prototyping

Delaying risk hazard analysis can lead to a significant increase in product development costs. In the intricate world of medical device design, starting your risk hazard analysis during the prototyping phase is more than just a best practice; it's a strategic advantage. Conducting these assessments early—albeit informally—enables teams to identify and mitigate potential risks before they become woven into your product's architecture.

Key Benefits of Early Risk Analysis

1. Reduced Project Costs and Timelines: Making architectural changes based on risk findings during prototyping is substantially less expensive than addressing issues during detailed design or manufacturing stages. Early analysis helps avoid costly redesigns that can derail project budgets and timelines.

2. Risk-Driven Prototype Design: Planning your prototype specifically to evaluate potential risks creates purposeful development iterations. By designing prototypes that intentionally test high-risk areas, you can validate safety controls early rather than discovering problems after architecture decisions are locked in.

3. Informed Design Decisions: Analysis of energy hazards (electrical, acoustic, physical, biological) leads to safer design choices from the beginning, preventing the need for last-minute compromises.

4. Increased Flexibility: Prototyping with risk in mind allows for testing and adaptation before designs become finalized and more difficult to change.

   
   

Focus Areas During Prototyping Risk Analysis

While each medical device presents unique risk considerations, ISO 14971 highlights several critical areas to address during early assessment, including:

• Energy Hazards: Evaluate electrical, acoustic, mechanical, and radiation risks

• Biological and Chemical Hazards: Consider biocompatibility, toxicity, and allergenicity

• Operational Hazards: Assess function failure modes and their consequences

• Information Hazards: Examine risks related to labeling, instructions, and warnings

• Usability Hazards: Identify potential user errors and their impact on safety

• Software-Related Hazards: Evaluate data integrity, cybersecurity, and algorithm reliability

  
  

This represents only a subset of potential hazard categories to consider. A comprehensive approach should follow the systematic process outlined in ISO 14971, which includes risk identification, analysis, evaluation, control, and ongoing monitoring.

Take Your Prototyping to the Next Level

Integrating risk analysis into prototyping delivers substantial benefits:

• Significantly reduced development costs

• Accelerated time to market

• More robust architecture that doesn't require late-stage redesigns

• Enhanced regulatory readiness

• Superior product safety profile
