5 Confirmation measures From ISO Tab.2 Confirmation Reviews Functional Safety Audits Functional Safety Assessments Subject Work product Implementation of the processes required for functional safety Item System(s) to implement a function at vehicle level Responsibility of the Appraiser Evaluation of the work product compliance vs. ISO requirements Evaluation of the implementation of the processes required for the functional safety Evaluation of the achieved functional safety. Recommendation for acceptance, conditional acceptance or rejection Timing during the safety lifecycle After completion of the corresponding safety activity. Completion before the release for production During implementation of the required processes Progressively during development, or in a single block. Completion before the release for production Scope and depth In accordance with the safety plan Implementation of the processes against the definitions of the activities referenced or specified in the safety plan Work products required by the safety plan, implementation of the required processes and a review of the implemented safety measures that can be assessed during the item development 18 aprile
