     \section{Complexity}
+        The goal of this thesis is to investigate how the design method for the embedded software in a cyber-physical system can be applied to the physical part.
+        The setup of the design method and applying that method in the case study pointed out that there is an enormous difference between the cyber and physical part.
+        This difference in presents itself in development cost and system complexity.
+
+        \subsection{Complexity}
+            Almost every complex system that is produced today contains software.
+            Software is often the reason that the complex system can exist in the first place.
+            Where software can have millions of states, configurations and variables, hardware is often limited to a dozen of states.
