Excellent 👍... By the way, I have a question regarding HARA part, while deriving an ASIL level to the HAZARDS, OEM & product owner (Tier1 supplier) may varies with the S,E,C parameters based on their respective analytics and field observations & OEM may end up in defining lesser ASIL level for a Hazard which is given a Higher ASIL by Supplier. Ofcourse, I understood that OEM is the responsible for defining an ASIL level & OEM better knew the vehicle level hazards and impacts, but the experienced product owner comes with an ASIL level based upon various iterations. In this case how this risk will be taken care of, either with OEM's lesser ASIL level (since the OEM is ready to accept the consequences of the lesser ASIL) or we should stick on the Supplier's highest ASIL level ? Hope my question is clear. What is your view with this practical problems.
Thanks in advance.... All the Best👍
