13 Upcoming Meetings NGAO Science Case meeting at CfAO retreat Mar. 28 –Need to determine if this meeting can go ahead SSC meeting Apr. 3 –2 nd project report to SSC & Observatory management Will need a written report Need financial reports from COO & UCO –We need to complete the Science Case Requirements v1.0 & Performance Budget Summary v1.0 milestones, & if possible the System Requirements v2.0 milestone –We need to show a plan to get on-track (this will be our mid-year replan) NGAO Team Meeting #6 Apr. 18 at UCSC –Need to post agenda –Need to find a better way to prepare for meetings. Materials should be posted several days before the meeting to allow pre-reading & more effective discussion at the meeting.

14 Team Meeting Calendar

15 PW Recommended Priorities for March (needs discussion) Complete mid-year replan –Include solutions to accelerate progress in the following areas: Science Case Requirements Performance Budgets & Trade Studies Science Instruments –Include revision to meeting goals (& potentially schedule) Complete milestones –V1.0 of Science Case Requirements & Performance Budget Summary Support Science Case meeting at the CfAO (3/28) Complete WBS elements that have been started –This includes completion as a KAON –Should include review by an EC member or their delegate –Don’t start any new WBS elements until you have completed these Project Report #2 ( due before Apr. 3 SSC meeting ) & SSC presentation
