J. Linnemann, MSU 12/16/ Commissioning l Limiting factors: Stable, fully functional L2 Cards (ouch) ‚MBT’s with full functionality ‚FIC: lack of on-site expertise ‚ Lack of reliable system to modify firmware ‚Alpha: lack of firmware expertise on-site Manpower (trained—getting better) ‚Big conflict with ‚ Prototype testing (MBT, CIC, SFO) ‚ Production debugging (Alpha) ‚ Beta (fallback plan for Alpha) ‚Rick Kwarciany is part-time integration engineer Alpha software for commissioning ‚Limited, in turn, by above problems Availability of inputs ‚Real, or test; becoming limiting factor
