To avoid systematic failures, well-trusted automotive design principles shall be applied: reuse of well-trusted technical safety concepts, element designs including HW and SW components, mechanisms for failure detection and control, standardised interfaces. Use deductive and/ or inductive analysis, dependent on ASIL.
