Originally designed to be efficient in hardware . A LOT of money has been invested in hardware. although DES standard is public there was considerable controversy over design – in choice of 56-bit key (vs Lucifer 128-bit) – and because design criteria were classified

Failure modes Noises lead to failure modes(Fm) One set of noise values leads to fm Opposite set of noise values leads to FM Simple problem solving chases the problem from Fm, to Fm, and back again but does not avoid both fms with the same set of design values-endless cycles of build/test/fIx(B/T/F) C Don Clausing 1998 6.881

Case study An automatic document handler(adh)was developed at the ss level. When integrated into the total system there were many new problems. The TQM Problem Solving Process was used, and many problems were solved. However. at the field readiness Test (frt) before entering production the reliability was 15X worse than acceptable O Don Clausing 1998

The general approach Earlier Parts have given a broad picture of the economic environment within which marine transport operates, and the mechanics of making economic calculations. Ship design links the two, i.e., the marine transport requirements must be developed into a series of feasible ship designs
