 \subsection{Determining the failure modes of components}
 \label{sec:determine_fms}
 In order to apply any form of Failure Mode Effects Analysis (FMEA) we need to know the ways in which the components we are using can fail.
+A good introduction to hardware and software failure modes may be found in~\cite{sccs}[pp.114-124].
 Typically when choosing components for a design, we look at manufacturers' data sheets,
 which describe the environmental ranges and tolerances, and can indicate how a component may fail/behave
 under certain conditions or environments.
