The rapid growth in use of programmable technology, in nearly all
sectors of Engineering, is a well-known established trend and one
which there is every reason to believe will continue into the
foreseeable future. The drivers of this trend include cost,
flexibility, rich functionality and certain reliability and safety
advantages. However, as explained in this book, these advantages
have to be carefully weighed against a number of dis advantages
which, amongst other things, have fundamental implications for
reliability and safety. Ideally, a programmable system would be
viewed as a fusion of hardware, software and user (or 'skinware'),
operating under a set of environmental conditions. To date, such a
unifying model does not exist and so hardware, software and human
factors are still considered largely as three separate disciplines,
albeit with certain interdependencies. Established techniques are
available which enable the engineer to develop systems comprising
purely hardware components to a prescribed reliability and
performance. Software, however, is fundamentally different in a
number of ways, and does not lend itself to equivalent analysis. A
major problem with software is its poor 'visibility', and
consequently the great difficulty in understanding and predicting
its behaviour in all cir cumstances. This results in the
ever-present software design flaws, or 'bugs', which have plagued
the software industry from its beginnings."
