Evidence-Based Error Analysis: Supporting the Design of Error-Tolerant Systems

Abstract

This paper proposes an evidence-based process and engineering design tool for linking human error identification taxonomies, and human error prevention and mitigation design principles with the system engineering design process. The process synthesizes the design evidence generated and used during the design and analysis process to clearly demonstrate that credible error threats have been identified and considered appropriately in the design of the system. In doing so, it supports the designer in managing design solutions across the entire design process, leaves a design trace that is transparent and auditable by other designers, managers, or certification experts, and manages the complex interactions among other systems and sub-systems.Keywordserror-tolerant designhuman errordesign rationaledesignVUE
