Vehicle with digital lines and code

This training offers a comprehensive introduction to Dependent Failure Analysis (DFA) in the context of functional safety in accordance with ISO26262. It teaches participants how to show independence and freedom from interference, and reinforces this through practical exercises. Participants learn what types of failures (common cause failures (CCFs) or cascading failures (CascFs)) are relevant to decompoisitions or coexistence. They also learn what measures need to be integrated into the safety concept in order to reduce the risk of dependent failures to an acceptable level.

Objective and training content

After completing the training, participants are able to identify dependencies and risks in their projects, evaluate them, and develop suitable failure avoidance and management strategies. They understand the differences between common cause and cascading failures, are familiar with the procedure for a DFA, and can help draw up or optimize safety-relevant concepts.

Training content:

  • The objectives and significance of a DFA
  • Definition of key terms: common cause failures, cascading failures, coupling factors, dependent failure initiator
  • Showing independence and freedom from interference (FFI)
  • The DFA procedure as a systematic method
  • Practical exercise and case study

The content of the training can be tailored to your project-specific requirements and questions.
