Description
The Dish Array CoDR is the review of the DVP and associated work conducted at element level during the Concept Phase. The review panel members are: 1) Roger Norrod (NRAO)(retd.) (Chairman) 2) Trevor Bird (Antengenuity/CSIRO) 3) Peter Dewdney (SPDO) 4) Bob Plemel (SED Systems)(retd.) 5) Tony Willis (NRC‐HIA) The CoDR will be conducted to evaluate: A) The overall progress in the Domain B) Whether the technical adequacy obtained during the concept phase is at a sufficient level of maturity to allow the Dish Array Element to move into the next phase. C) Whether all Dish Array Element aspects of the project have been covered and where gaps exist, whether adequate measures have been identified to address the shortcomings. The expected outcome of the review is the establishment of the Dish Array concept baseline. The Review Panel is requested to consider the following questions: 1. Are the requirements complete, and sufficiently defined for this stage of the project? 2. At the concept level, is the element/subsystem presented capable of meeting the requirements? 3. Have interfaces to other aspects of the system been adequately identified and defined at this stage of the program? 4. Are the options proposed to be carried forward credible and are the presented data and information in support of each option credible? 5. Have all the necessary aspects of the specific element/subsystem been considered and addressed during the review or are there gaps and/or shortcomings? 6. Does the risk profile appear reasonably detailed and correctly assessed for this stage of the program? 7. Do the stated risk controls and proposed mitigations appear reasonable and executable? 8. Is the overall plan (including the identification of the tasks, effort, resources, costs, schedule and risk mitigation needed) to complete the subsequent project phases credible? These questions are to be within the context of SKA1 but with consideration of extensibility to SKA2, and the plans to correlate with the evolving project environment
