Should a functional requirement to prevent unintended misuse of a product be developed as ASIL?
During the FuSa Connect, we had an interesting question from one of the functional safety managers. " I have functional requirements provided by the Customer for preventing foreseeable misuse by the driver. However, the OEM insists that I implement these with ASIL compliance. Aren't these requirements related to SOTIF? If so, should I implement them as ASIL?
