Teams that fail to submit the PDR, CDR, FRR milestone documents will be eliminated from the project. In other cases, a single review or series of focused Design TIMs are held in their place, which accomplish the intent. A preliminary CDR agenda, success criteria, and charge to the board have been agreed to by the technical team, project manager and review chair prior to the CDR. The following items and issues are addressed at the CDR, where applicable: Functional description and block diagram. RockSat-X engages students in a thorough design process, documented by design reviews (CoDR, PDR, CDR) in the fall and testing and integration reviews (STR, ISTR, FMSR, VVC) NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery. 3.

Teams will present their PDR, CDR, and FRR to a review panel of scientists, engineers, technicians, and In the NASA life-cycle, two key reviews are the PDR and CDR. gov . 5D Note that because CDR is not the final review of the flight design for a rocket engine, there can be a handful non-milestone check-point meetings during the years that follow the CDR. • Tailorable Entrance/Exit Criteria • Products required at each review. 29 will be validated, which may not be demonstrated by requirements verification alone. If an existing hardware, software, or design element is being inherited, then the subsystem CDR agenda items also need to be considered. NASA missions are becoming increasingly complex, and the challenge of engineering systems to meet the cost, schedule, and performance requirements within The list of reviews done by an effort and the content, nature, process, and objectives any review uses vary enormously by the organization involved and the particular situation of the effort.
