Software System Safety Engineering Training

Software System Safety Engineering Training is a 3-day crash course style covering all aspects of Software System Safety Engineering (SSSE). The 3-day bootcamp focuses on Software System Safety (SwSS) and its primary objectives: to design, code, test, and support software with the appropriate Level‐of‐Rigor (LOR) to instill a confidence, or the assurance of safe software; and to define the necessary safety requirements for the design, code, test, verification, and validation of software that specifically target and mitigate the software “causes” of the defined hazards and mishaps of the system.

Software system safety is a subset of system safety and system engineering and is synonymous with the software engineering aspects of Functional Safety.

Learning Objectives

Software System Safety Engineering Training would help participants learn the following upon completion:

  • The need for Software System Safety (SwSS) and the relationship between system safety and SwSS
  • Directives, documents, policies and regulations related to SwSS
  • The detailed instruction on the SwSS process, including a variety of analyses and tools
  • Planning details for a SwSS program to include hazard identification, tracking, risk assessment, risk reduction and risk acceptance as applicable to SwSS

Who Should Attend

Software engineers, safety engineers, system engineers, Testing and V&V engineers and project managers, analysts and anyone else who is interested to acquire skills in software system safety.
