Separated out the abstract from the paper, so that I can work on the abstract

in isolation.

%The certification process of safety critical products for European and

component failure modes on a system.
It is used both as a design tool (to determine weaknesses), and is a requirement of certification of safety critical products.
FMEA has been successfully applied to mechanical, electrical and hybrid electro-mechanical systems.

Software generally, sits on top of most modern safety critical control systems
and defines its most important system wide behaviour and communications.
Currently standards that demand FMEA for hardware (e.g. EN298, EN61508),
do not specify it for Software, but instead specify, good practise,
review processes and language feature constraints.
This is a weakness; where FMEA % scientifically
traces component {\fms}
to resultant system failures, software has been left in a non-analytical
limbo of best practises and constraints.

If software FMEA were possible, electro-mechanical-software hybrids could
be modelled; and could thus be `complete' failure mode models.
%Failure modes in components in say a sensor, could be traced

Presently FMEA, stops at the glass ceiling of the computer program.
This paper presents an FMEA methodology which can be applied to software, and is compatible
and integrate-able with FMEA performed on mechanical and electronic systems.
