Purpose
The purpose of this Safety Analysis (DFA and FMEA) formal review report template is to collect the topics to be checked during verification of the Safety Analysis.
Conduct
As described in wf__p_formal_rv, the formal document review is performed by an “external” safety manager:
reviewer: <committer with safety manager skills explicitly named here>
scope: <describe the scope of the review here, e.g. “the safety analysis of the module and its results”>
Checklist
Please note that it is mandatory to fill in the “passed” column with “yes” or “no” for each checklist item and additional to add in the remarks why it is passed or not passed. In case of “no” an issue link to the issue tracking system has to be added in the last column. See also doc_concept__wp_inspections for further information about reviews in general and inspection in particular.

DFA 1 |
Are the potential dependent failures identified by performing a DFA? |
[YES | NO ] |
<Rationale for result> |
|
DFA 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 ] |
<Rationale for result> |
|
DFA 3 |
Are applicable operational situations and operating modes considered? |
[YES | NO ] |
<Rationale for result> |
|
DFA 4 |
Are the failure initiators gd_guidl__dfa_failure_initiators suitable and applied? |
[YES | NO ] |
<Rationale for result> |
|
DFA 5 |
Is a rationale provided for each identified potential dependent failure? |
[YES | NO ] |
<Rationale for result> |
|
