  1. What documents would you expect to see or produce to validate the suppliers COTS equipment and integration into the overall Control and Monitoring Systems at the Design Stage. 
  2. What approaches or Strategies could be used to validate the performance and verify the design intent post equipment Specification. 
  3. What standards apply for the equipment architecture and system parameters shown 
  4. What safety requirements are relevant to this equipment and how would these be identified and substantiated 
  5. Explain the system high failure modes and what mitigations you would consider to ensure a safe by design solution
