Design Variables and Influences
failure modes
Established standards help in development e.g. address requirementsand required reliability to sub-system and components
Define how design engineering support top-down safety methods
parallelizationof work on different item levelsRequirements and assumptions can be validated at each hierarchical level of requirements definition (FHA, function, system and item levels)
frontloadingof improvements and therefore verified design quality,speed up of development process, to fulfil functions and increase reliability

in the loop (MiL, SiL, HiL) based optimization, early design verification loops to decide evidence based, to achieve reliable robust design from the initial stage
Models (in the loop) and verifications in different levels help to archive a reliable design from the initial stage.
