Common use of Design Reviews Clause in Contracts

Design Reviews. Preliminary Design Reviews (PDRs) and Critical Design Reviews (CDRs) shall be conducted at the spacecraft system level. Each design review shall be comprehensive, critical audit of the design. The design review program shall not only encompass a thorough review of new hardware designs and modified designs, but shall also take into account those existing qualified designs that will result in the achievement of the XM performance and environmental requirements. Without relieving the Contractor of its responsibilities for efforts under the Contract, the XM Project Manager will co-chair system level design reviews. The Contractor shall provide the logistics for these reviews, shall make the review presentations, and shall provide required documentation as described within the CDRL. The Contractor shall compile and maintain a uniform program listing of all action items. The status of these action items shall be tracked through closure. 3.2.1 SPACECRAFT PRELIMINARY DESIGN REVIEW (SPDR) The purpose of the SPDR is to allow XM and the Contractor to confirm the baseline concept, configuration, specifications, and preliminary design of spacecraft system. The design review package shall be submitted in accordance with the CDRL. XM shall have the right to approve the review including completion of the review, review meeting minutes, and Major Action Item responses.

Confidential treatment has been requested with respect to the omitted portions. The SPDR shall comprise a comprehensive review of the requirements for the spacecraft and their flowdown to the major subsystems, particularly the communications payload. Also to be covered, shall be the identification of new items to be developed or items to be modified in order to meet requirements of the Contract. A comparison of specified and expected performance for the communications payload (repeater and antennas) shall be reviewed. An analysis of [***] shall be presented. A [***] shall be reviewed. The Contractor shall review and present the requirements on the spacecraft control equipment (ground segment hardware and software) and shall describe the operations concept. 3.2.2 SPACECRAFT CRITICAL DESIGN REVIEW (SCDR) The purpose of the SCDR is to allow XM and the Contractor to confirm the adequacy of the spacecraft system design, system performance, and system test plans. XM shall have the right to approve the review including completion of the review, review meeting minutes, and Major Action Item responses. The SCDR shall comprise a comprehensive review of all new designs, and any major modified existing design. The spacecraft performance shall be reviewed to verify compliance with contractual design and performance requirements. Compliance data for existing designs presented at the SPDR shall not need to be presented at this review. Compliance shall include a presentation of predicted and measured performance compared to contractual requirements. [***] shall be documented. A preliminary version of the Mission Sequence of Events shall be presented at the review. Changes since SPDR and recommendations from product line problem review teams (if any) related to XM as well as the status of their implementation on XM spacecraft shall be presented.

Design Reviews. Preliminary ‌ Except as mutually agreed upon by Developer and IFA, all Design Reviews shall be conducted in the Project Office. IFA will provide ▇▇▇▇▇ ▇, ▇▇▇▇▇ ▇ where applicable, RFC, and Final Design Design Reviews. Each of the Design Reviews (PDRsfor each stage of design development) will consist of three phases. Phase 1 shall consist of informal, brief presentations (sometimes known as over-the- shoulder reviews) during the development of design at the review office by the Responsible Engineer of the Design Unit being reviewed and Critical Design Reviews (CDRsthe other Developer staff. The presentations shall include an explanation of what component(s) are being reviewed, highlighting any critical points or other information that may be of particular interest to the review participants. Phase 2 shall be conducted a period of more detailed review by the review participants. For minor items with little complexity, and although it is expected that most Phase 2 reviews will take place in the Project Office, Phase 2 shall, as necessary, provide for review participants to take the review package to their own offices for further examination, particularly for complex and, sensitive features. During this period, reviewers are encouraged to contact or meet with the Responsible Engineer to gain further understanding of the design intent of discuss the reviewers issues. The length of Phase 2 shall be consistent with the durations agreed to at the spacecraft system leveldesign workshop or as subsequently agreed to in writing. Each design review shall be comprehensiveIFA’s Phase 2 written comments, critical audit of the design.
