Safety Analysis Workflows
#########################

For a detailed explanation of workflows and their role within the process model, please refer to the :ref:`processes_introduction`.

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

.. workflow:: Analyze Platform Feature Architecture
   :id: wf__analyse_platform_featarch
   :status: valid
   :tags: safety_analysis
   :responsible: rl__safety_engineer
   :approved_by: rl__safety_manager
   :supported_by: rl__contributor, rl__committer, rl__security_manager
   :input: wp__requirements_feat, wp__feature_arch, wp__issue_track_system
   :output: wp__platform_dfa
   :contains: gd_guidl__dfa_failure_initiators, gd_temp__plat_saf_dfa
   :has: doc_concept__safety_analysis, doc_getstrt__safety_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.

   :has: doc_concept__safety_analysis, doc_getstrt__safety_analysis

   | The FMEA and DFA for the feature is executed.

   :has: doc_concept__safety_analysis, doc_getstrt__safety_analysis

   | The FMEA and DFA for the component is executed.

   :has: doc_concept__safety_analysis, doc_getstrt__safety_analysis

   | The FMEA and DFA are monitored.

.. workflow:: Verify FMEA and DFA

   :has: doc_concept__safety_analysis, doc_getstrt__safety_analysis

   | 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.
