\subsection{Workflow process PartyParty}

\subsubsection{Scenario 1}

The costumer orders a party. He pays with cash. The company can deliver the goods with their own van.

By the returning of the goods it turns out that there are goods damaged, and the costumer refuses to pay the fine. \\

\end {center}
Step 14:
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_21.png}
\end {center}
Step 15:
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_22.png}
\end {center}
Step 16:
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_23.png}

\end {center}
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_27.png}
\end {center}
Step 19: After sending the fine, the Times Sent will be automatically increased.
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_28.png}
\end {center}
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_29.png}
\end {center}
Step 20: Here can be seen that the Times Sent is increased. If the Fine isn¿t payed, this process will increase the amount automatically with 5\%.
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_30.png}
\end {center}
\begin {center}
  \includegraphics[width=\textwidth]{YAWL_Engine_PartyParty_Scenario_1_31.png}
