Level 4 Budget by FY labor estimate is low and does not include configuring multiple systems S. Williams 14
Issues & Mitigations Multiplicity of systems required to support parallel development efforts Enforce commonality of basic infrastructure. Provide data distribution over ethernet to support subsystem specific and engineering data displays. Use COTS hardware and software as much as possible to control cost. KISS. Leverage RTOS interface systems development off flight software development. Leverage out-years maintenance from IOC. Initial need date of 11/01 is aggressive Begin development immediately. Leverage recent Balloon Flight development. Obtain subsystem buy-in via IPT. Trade studies delayed by Balloon Flight Perform in parallel to EM1 development S. Williams 15
