Another large part of the design process are design reviews. For a design review, the team pulls together information of varying detail about our design and mission, and presents it to an audience. The audience, level of detail, and subject matter depend on the type of design review. In industry, you will see many design reviews, including but not limited to, Preliminary Design Review (PDR), Critical Design Review (CDR), and Flight Readiness Reviews (FRR). On rocket team, we usually focus on PDR and CDR.
