Getting Started

This document outlines the steps for performing, monitoring, and verifying Safety Analysis. Safety Analysis is used as a umbrella term for the methods DFA (Dependent Failure Analysis) and FMEA (Failure Mode and Effects Analysis). The concept of performing Safety Analysis is described in Safety Analysis Concept (doc_concept__safety_analysis). The verification of the architecture is described in Architecture Process (doc_concept__arch_process).

Safety Analysis Steps#

The goal of the Safety Analysis is to proof that the safety requirements for functions and safety mechanisms are not violated. The Safety Analysis is performed in three steps.

  • Analyse the architecture with a DFA and FMEA.

  • Monitor the DFA and FMEA and log any issues in the Issue Tracking system with the safety label until the analysis is completed.

  • Verify the FMEA and DFA results by using Safety Analysis Checklist T... (gd_chklst__safety_analysis). The Safety Analysis are completed when the verification is done, no issues are open and the status is “valid”.

The details of what needs to be done in each step are described in the Safety Analysis (DFA and FM... (gd_guidl__safety_analysis). For the Safety Analysis templates are used. The templates are described in the FMEA Templates and DFA Templates.
