Main Description

This role only exists within projects developing safety critical systems or applications. This  role is active throughout the project development and participates and oversees the following activities:

  • Specifying safety requirements
  • Analyzing work products for safety, including
    • Requirements
    • Use Cases
    • Requirements scenarios
    • Architecture
    • Algorithms
    • Classes, functions, and variables
    • Test suites and test cases
    • Configuration Management approach
  • Performing fault tree analysis (FTA) to determine relations of faults, hazards, risks, and control measures
  • Reviewing work products for adherence to safety requirements and/or regulations
  • Performing traceability between safety requirements and work products

With the explicit allocation of responsibility for safety, safety critical projects can be run more efficiently and productively, while reducing the risk of failing to meet the safety needs of the developed product.

Staffing
SkillsThis role needs to understand the safety impact of normal operation as well as failure states and modes for the system and system elements. This role must be able to perform the mathematical analysis to determine safety and interpret the results of that analysis. This role must be able to perform Fault Tree Analysis (FTA) (or its equivalent).
