Safety Analysis Checklist

[Your Feature Name] Safety Analysis Checklist		status: draft security: YES safety: ASIL_B
tags: template, feature_name realizes: wp__fdr_reports
doc__feature_name_safety_analysis_fdr		Generic Document

Attention

The above directive must be updated according to your Feature.

• Modify Your Feature Name to be your Feature Name

• Modify id to be your Feature Name in lower snake case preceded by doc__ and followed by _safety _analysis_fdr

• Adjust status to be valid

• Adjust safety, security and tags according to your needs

Purpose

The purpose of this Safety Analysis (DFA and FMEA) checklist template is to collect the topics to be checked during verification of the Safety Analysis.

Conduct

As described in Perform Formal Reviews, the formal document review is performed by an “external” safety manager:

• reviewer: <committer with safety manager skills explicitly named here>

Checklist

Please note that the “passed” column must contain “yes” or “no” for each checklist item. Additionally, the remarks column must explain why item passed or did not passed. In case of “no” an issue link to the issue tracking system has to be added in the last column. See also Review and Inspection Concept for further information about reviews in general and inspection in particular.

1	Are the safety analysis performed according to the defined process and templates? See Safety Analysis Process Requirements and also FMEA Templates and DFA Templates	[YES | NO ]	analysis_841	<Rationale for result>

3	Are for all not complied safety requirements mitigations defined to resolute the non-compliance? The mitigations shall have a direct influence on the violation by prevention, detection or mitigation to reduce the risk to an acceptable level.	[YES | NO ]	analysis_843	<Rationale for result>
4	Are the mitigations effective and implemented?	[YES | NO ]	analysis_844	<Rationale for result>
5	Are newly identified hazards adressed to be considered in HARA in the safety manual?	[YES | NO ]	analysis_845	<Rationale for result>
6	Are additional safety-related test cases determined by potential results of the safety analyses?	[YES | NO ]	analysis_847	<Rationale for result>

1	Are the potential dependent failures identified by performming a DFA?	[YES | NO ]	analysis_741	<Rationale for result>
2	Is it plausible that each potential identified dependent failure that has been identified, will lead to a dependent failure which cause a violation of FFI?	[YES | NO ]	analysis_742	<Rationale for result>
3	Are applicable operational situations and operating modes considered?	[YES | NO ]	analysis_743	<Rationale for result>
4	Are the failure initiators DFA failure initiators suitable and applied?	[YES | NO ]	analysis_744	<Rationale for result>
5	Is a rationale provided for each identified potential dependent failure?	[YES | NO ]	analysis_745	<Rationale for result>
6	Are measures defined to resolute the identified potential dependent failures?	[YES | NO ]	analysis_746, analysis_747	<Rationale for result>
7	Can be the required level of independence shown for the identified potential dependent failures?	[YES | NO ]	analysis_748	<Rationale for result>
8	Are the templates for DFA used? See DFA Templates and also Safety Analysis Process Requirements	[YES | NO ]	analysis_748	<Rationale for result>
9	Is the DFA performed in a systematic way to identify the potential dependent failures and their effects? Are the failure effect and the mitigation described?	[YES | NO ]	analysis_8410	<Rationale for result>
