% what I did
Looking at SYSTEMS ENGINEERING concepts.
FMMD static design analysis tool, but can be applied to product life cycle
Becomes a living analysis tool
% what I found
Alterations required in a failure mode model arise from
new failure modes discovered in base components, new failure mode behaviour observed
in {\dc}s, and environmantal effects found that interact with the failure mode model.
% conclusion
FMMD analysis can be updated with these three effects
and we can apply procedures that will automaically force
the uncoverig of new possible SYSTEM failure modes.

Ref Nacy Leveson, system eng.
A sub-system or system has its own behaviour etc
These may be traced to combinations of afailure modes
but may be undiscovered in initial analysis.

An environmental effect may be found to affect a sub-system.
Show how this vcan be retro fitted into a working/live FMMD model.
