Application

Design takeaway

Proactively identify and mitigate potential failure points in user environments by employing structured risk analysis techniques like FMEA and SHERPA, prioritizing interventions based on risk.

How to apply

When designing products or services for home environments, use FMEA to map out potential failures, their causes, and their effects, and then use SHERPA to generate a comprehensive list of potential issues and recommendations for mitigation.

Project actions

  • 01When analyzing your design, consider using FMEA to identify potential failure modes and their causes.
  • 02Use SHERPA to brainstorm a wide range of potential issues and solutions for your design.

Method & Evidence

AimTo determine if common failure modes, causes, effects, and recommendations can be identified across different analytical techniques when applied to home care scenarios.
MethodComparative analysis of analytical techniques
ProcedureTwo pilot home visits were conducted to gather data. Various analytical techniques, including Use Case Diagrams, Process Flow Diagrams, Hierarchical Task Analysis, Failure Mode and Effects Analysis (FMEA), Systematic Human Error Reduction and Prediction Approach (SHERPA), Hazard Analysis and Critical Control Point (HACCP), Heuristics, the Safe Living Guide, and the Resident Assessment Instrument – Home Care (RAI-HC), were applied to this data. The time taken for each technique and the commonality of their outputs were measured and reviewed.

Strengths & Limitations

Strengths

  • +Compares multiple established analytical techniques.
  • +Provides quantitative data on time taken and qualitative data on output commonality.

Limitations

The findings are based on a limited number of case studies, and the effectiveness of these methods may depend on the complexity of the design and the experience of the analyst.

Reliability & validity

The study's validity is supported by the comparison of multiple techniques, but its reliability might be limited by the small sample size of pilot visits.

Think critically

How might the effectiveness of FMEA and SHERPA be influenced by the specific domain or user group being considered?

Design Principles

"Employ systematic failure mode and effects analysis to anticipate and mitigate risks in user-centric designs."

Understanding potential points of failure in user environments is crucial for designing safer and more effective systems. By employing structured analytical techniques, designers can anticipate risks and implement preventative measures, leading to improved user experience and reduced negative outcomes.
