IMA cost indicators and prediction • LCC cost drivers (RC & NRC): � design & development cost & risk � hardware, mechanical, data/signal interconnects, power interconnects � use of standard components, OS, � complexity � certification aspects � re-useability (future savings) � weight/size/power/cooling � installation � maintenance, support (NFF, spares, rel., org.) � etc. - IMA does not have an intuitively obvious bottom line advantage - 94 ©1995-1997 F.M.G.
