Safety Analysis Workflows

For a detailed explanation of workflows and their role within the process model, please refer to the Introduction.

Safety Analysis is used as a umbrella term for the methods FMEA (Failure Modes and Effects Analysis) and DFA (Dependent Failure Analysis).

With a platform DFA the potential common usage of features shall be analysed. It shall be used as an input for all other DFA’s. There will be only one platform DFA.

The FMEA and DFA are monitored.

The FMEA and DFA are verified. The verification criteria is that it can be proven that the safety requirements for functions and the corresponding safety monitoring are not violated.
