Safety analysis in sphinx-needs?

[k-radlak]

Hi,
do you plan to add to sphinx-needs new features which could support safety analysis such as FMEA or FTA in docs as code approach?

Maybe we can create the list of the failure modes for every software component similarly as requirements and then we can have a similar fuctionality such as needflow to visualise?

In case of FMEA, we create the componentes, then assign functions to this components, and create failure modes for each function, but curently we cannot visualize the dependencies between them in the form of Fauilure Nets or Function Nets.

It would be very powerful tool when we can manage complete safety development lifecycle in a single text based tool.

Hey,
I'm not familiar with the terms FMEA/FTA, but I guess we and other have already done it by performing an ISO 26262 toolchain classification and qualification for a docs-as-code toolchain (containing Sphinx, Sphinx-Needs and other extensions).

Unfortunately, the documentation is not Open-Source, but at least I could release a demo-project, how to do it.

The used model was:

graph TD;
Tool-->Function;
UseCase-->Function;
Function-->Error;
Error-->Restriction;
Error-->Check
Check-->TestCase;
Restriction-->Script;

Loading

We used this data then to create dashboards of missing testcases or CI scripts and for sure to show the complete flow.
