Project phases

• Situation
  • Typically products are not developed from scratch but evolve from existing products
  • Design engineers lack experience with ISO IEC functional safety requirements and are left in uncertainty what and how to carry on from the existing products
• Verification-driven Design & Documentation
  • Start the project by verification of existing products and design drafts
  • Collect all existing requirements
  • Systematically analyze existing products and design proposals for safety even if based on “presentation slides”
  • Collect the analysis results by means of derived requirements
  • Structure and allocate all work items in a RACI chart
