 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,
