2. Presentation Sequence • Review of SEMP Status • Review of Replan • Budget • Next Steps

3. SEMP Status

4. SEMP Tracking • Tracked (Excel) version of the plan posted at http://www.oir.caltech.edu/twiki_oir/pub/Keck/NGAO/SystemDesignPhasePlanning/NGAO_SD_schedule_v20_tracked_final.xls • Excel version highlights what’s complete, what’s late, what’s due within next month & status of work scope planning sheets.

5. SEMP Summary 1 • WBS 1. SD Phase Management • On-schedule, except for replan (~ 1 month late) • WBS 2.1. Science Requirements • 1 work scope planning sheet approved. No others submitted. • All 13 science cases scheduled for completion by end of April. None completed. • Version 1 of Science Case Requirements complete. Version 2 due in Mar/07 • WBS 2.2-2.3. System Requirements Document • 1 planning sheet approved, 2 late. • Version 1 complete. Version 2 due in March. Need more feedback, especially on science operations requirements. • Version 1&2 of traceability matrix late.

6. SEMP Summary 2 • WBS 3.1.1. Performance Budgets • 8 planning sheets approved, 1 submitted, 5 late. • Model assumptions. 3 complete & 1 on schedule. • Model/tool validation. 3 complete & 2 late. • Performance budgets. 1 complete, 6 late (2 others due later). • Version 1 of summary late. • WBS 3.1.2. Trade Studies (29 total) • 12 planning sheets approved, 1 needs changes, 11 late. • 9 complete, 1 cancelled & 15 late. • WBS 3.1.3. System Architecture. • Version 1 should have started, but hasn’t. • WBS 3.4. Science Operations • 2 WBS elements should have been started pre-March, but haven’t & another 5 should have started in Mar. • WBS 3.5 Science Instruments • Only Interferometer started. 4 others should have been started & 1 is late. • WBS 4 SEMP • No significant work planned yet

10. Reasons for Replan • Significantly behind schedule • Behind on earned value: 29% of labor & dollars spent, but plan only 24% complete • Planned opportunity (scheduled in SEMP) to revisit plan approach, priorities, tasks, personnel, dictionary definitions, etc. • We also need to improve how we are managing this project • Schedule and budget are tools in accomplishing the project

16. Budget Reduction in replan labor largely due to removing 1230h of students

17. Next Steps • Complete Replan with Team’s input • Determine how to proceed with System Architecture • New & revised WBS dictionary definitions • Improved management strategies • More focused team • Redo team meeting goals • Complete the following items in May: • SCRD & SRD v2 • FRD v0 & Science Instruments FRD v1 • Performance budgets summary • Trade Studies • Define Candidate Subsystems + Remember to do work scope planning sheets for new tasks
