Upcoming Meetings
• NGAO Science Case meeting at CfAO retreat Mar. 28
– Need to determine if this meeting can go ahead
• SSC meeting Apr. 3
– 2nd 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.

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
