 The techniques of the \ridm are incorporated on top of the waterfall model.
 This chapter will analyse the basics of a waterfall model, and analyse what the \ridm provides.

-One of the most basic design method for development is the waterfall model introduced by Royce
-\footnote{Interestingly, \textcite{royce_managing_1970} never called it waterfall himself, he also notes that it never worked for large software development efforts.} 
-in 1970 \autocite{blanchard_systems_2014}. 
-The simplest implementation has five steps as shown in \autoref{fig:waterfall}.
-Methods like the V-model or spiral model give significant advantage over the waterfall model, as they incorporate more evaluation and feedback, but are not as simple as the waterfall.
-This simplicity makes changing and adding design steps to the waterfall model possible.
+\textcite{blanchard_systems_2014} describe \ac{se} in their book as: "an interdisciplinary approach and means to enable the realization of successful systems."
+Their book extensively covers different design methods and design steps in detail.
+As these design methods are presented in complete detail, they are used as a basis for the design plan in this thesis.
+Multiple design methods are presented and one of the simplest design methods is the waterfall model.
+There are more elaborate methods available like the V-model or the spiral model, but are more interconnected due to build in feedback cycles.
+The waterfall model is usefull because it is a list of steps that are executed one by one as shown in \autoref{fig:waterfall}
+Because the steps are independent of each other, it is possible to insert or switch steps in the design method.
 
 \section{Rapid Iterative Design Method}
 The \ridm by \textcite{broenink_rapid_2019} describes a methodology using two core components for the implementation: the rapid development cycle and the variable detail approach.
