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
