Safety Analyses in the Context of ISO 26262

1 day

Date/Time Location Language
Upon request   English/German

Inductive and deductive safety analyses play an essential role within the ISO 26262 safety life cycle. Qualitative analysis methods are used to identify failures whereas quantitative methods are utilized to predict the frequency of failures.         

This one-day training class introduces the fundamentals of common safety analysis methods such as FMEA, FMEDA, and FTA and discusses the role of these methods in the development of safety-related E/E systems as per ISO 26262.

Target Audience

This training class is designed for automotive professionals (safety engineers, safety managers, system, HW and SW developers, engineering team leads, and managers) involved in the development of safety-related automotive E/E systems as well as anyone interested in learning about safety analyses techniques used in the automotive domain.


  • Classification of analysis methods (inductive vs deductive, qualitative vs quantitative)
  • Common safety analysis methods
  • Failure Modes and Effects Analysis (FMEA)
  • Failure Modes, Effects, and Diagnostic Analysis (FMEDA)
  • Fault Tree Analysis (FTA)
  • ISO 26262 hardware metrics (SPFM, LFM, PMHF)
  • Combining safety analysis methods
  • Role of safety analyses in the ISO 26262 safety life cycle
