\chapter{Case Study: Execution}
\label{chap:case_experiment}
This chapter presents the execution of the case study.
Where the goal of the case study is to evaluate the design plan as presented in \autoref{chap:analysis}.
To achieve this goal, I will develop a system according to the design plan and document this design process.
The system to be designed is chosen previously in \autoref{sec:sod}.
Documenting the process is done by following the evaluation protocol as described in \autoref{sec:evaluation_protocol}.
To start the case study unbiased, during the preparation I did perform as little preliminary research as possible on the design options of the "Tweet on a Whiteboard system".

The chapter begins with the section about the preparation phase, which contains the four corresponding design steps as shown in \autoref{fig:design_plan_analysis}.
This is followed by two completed development cycles in the later two sections.
Both of these sections cover the three steps that are shown in \autoref{fig:design_plan_analysis}.
Each design step is described in a separate subsection.
Herein, the result of the design step is presented and concluded with an evaluation section at the end.
This evaluation section discusses the pairs of questions that were answered according to the evaluation protocol (\autoref{tab:prepost}).
The questions regarding the design method itself are discussed in \autoref{chap:reflection}.

\section{Preparation Phase}
The preparation phase contains four design steps.
It begins with a problem description.
This description is detailed into a list of specifications.
Based on the specifications, a number of design solutions proposed and eventually one of these solutions is chosen as initial design.
Splitting the initial design into features is done in the feature definition step.
