What is the purpose of a CDR?
Purpose of the Critical Design Review (CDR) The purpose of a CDR is to assess a system’s final design as captured in product specifications for each Configuration Item in the system’s product baseline and ensures that each configuration item has been captured in the detailed design documentation.
What does Acars stand for?
