\chapter{Software}
Cutting-edge science increasingly relies on custom software. In their 2008 survey,
\textcite{HannayJoErskine2009a} demonstrated just how important software is to the modern
scientist. %
\begin{enumerate}[topsep=-1.5ex, itemsep=0ex, partopsep=0ex, parsep=0ex, label=$\rightarrow$]
\item 84.3\% of surveyed scientists state that developing scientific software is important or very important for their own research.
\item 91.2\% of surveyed scientists state that using scientific software is important or very important for their own research.
\item On average, scientists spend approximately 40\% of their work time using scientific software.
\item On average, scientists spend approximately 30\% of their work time developing scientific software.
\end{enumerate}
Despite the importance of software to science and scientists, most scientists are not familiar with basic software engineering concepts.
% TODO: demonstrate that `most scientists are not familiar with basic software engineering concepts'
This is in part due to the their general lack of formal training in programming and software development. \textcite{HannayJoErskine2009a} found that over 90\% of scientists learn software development through `informal self study'. Indeed, I myself have never been formally trained in software development.
Software development in a scientific context poses unique challenges. Many traditional software development paradigms demand an upfront articulation of goals and requirements. This allows the developers to carefully design their software, even before a single line of code is written. In her seminal 2005 case study \textcite{SegalJudith2005a} describes a collaboration between a team of researchers and a contracted team of software engineers. Ultimately
