schedule performance.Hardware shortages Weekly review of hardware availability

Additional personnel added to I&T Material Logistics



SummarySummary

• Current plan is to maintain two shift operation.• Utilize weekends maintain schedule.• Procedures, Drawings, MGSE and Flight Hardware in place to

support current Phase 0 plan.• Additional subsystem personnel have been identified to support LAT

I&T Operations.
