The past decade has seen a dramatic change in the emphasis of software
to hardware. Whereas a project may have comprised 80% hardware and 20
% software, the reverse is now generally more realistic. This has resu
lted in a great deal of interest focusing around the areas of quality
metrics and reliability growth applied to the software lifecycle. Risk
analysis has to date seen many applications in the assessment of hard
ware but little in the software area. This paper reviews the risk anal
ysis techniques that have been developed in a range of industries. Pro
gress in this area has been most apparent in the chemical and nuclear
power industries where probabilistic risk assessment has been used to
estimate the total risk associated with the whole plant. A discussion
of the appropriateness of the techniques to software safety assessment
is included together with an outline of the methods currently being u
sed to detect software faults. Suggestions are made for a new methodol
ogy in analysing software safety.
