This chapter describes a process for taking a functional group of components, applying FMEA analysis and then determining how that functional group can fail.
With this information, we can treat the functional group
as a component in its own right.
This new component is a derived component.
For a top down technique this would correspond to a low~level sub-system.
%The technique uses a graphical notation, based on Euler\cite{eulerviz} and Constraint diagrams\cite{constraint} to model failure modes and failure mode common symptom collection. The technique is designed for making building blocks for a hierarchical fault model.
Once the failure modes have been determined for a sub-system/derived~component,
This derived component can be combined with others to form functional groups
this derived component can be combined with others to form functional groups
to model

In this way a hierarchy to represent the fault behaviour
