PDR and CDR are acronyms used in the product development process. PDR stands for Preliminary Design Review, while CDR stands for Critical Design Review.
PDR is a design review that is typically conducted early in the product development process, when the design is still in the preliminary or conceptual stage. The goal of PDR is to evaluate the feasibility and feasibility of the design, and to identify any potential issues or challenges that may need to be addressed.
CDR is a design review that is typically conducted later in the product development process, when the design is more complete and has been refined and tested. The goal of CDR is to evaluate the design against the specified requirements and constraints, and to identify any potential issues or challenges that may need to be addressed before the product can be released.
Overall, PDR and CDR are important phases in the product development process, as they provide a structured and systematic approach to evaluating the design and identifying any potential issues or challenges that may need to be addressed.
