\section{Requirements}
The requirements are is ordered following the MoSCoW prioritization method. The
MoSCoW approach originated from the RAD methodology~\cite{clegg_case_1994}.
MoSCoW is used to sort the MarsRover features into priority order based on the
importance. In this way, the developers are able to understand what feature is
essential to be done. The term MoSCoW itself is an acronym derived from the
first letter of each of four prioritization categories (Must have, Should have,
Could have, and Would like but won't get). The first letters are used in the
first column of \autoref{tab:req} to describe the priority of the requirements.
