+Software FMEA
+
+
+No known method of software failure mode effects analysis--- some work has been done on
+Sofware FTA a top down approach---
+Bottom up approach means all known failure modes must be modelled.
+SIL does not have metric or tools to analyse software for saefty,
+it instead applies best practises and constraints on computer language features (i.e.
+in C limited use of pointers  no recursion etc).
+
+
+Introduce concept of FMEA
+* bottom up
+* all failure modes for all componnts
+
+Concept of FMMD
+
+Look at the structure of software
+* a natural hierarchy
+
+Software written for  a controlled
+Contract programming
+* describe concept
+* describe how this fits in with failure modes and failure symptoms concepts
+
+Describe how contract programming represents the failure modes of software
+
+Now describe how this fis in with the structure of FMMD
