+% Intro: end goal

+% Reflect Extend the RIDM with a preliminary design phase. This makes it possible develop a system for a given problem or idea, using this design method.
+The first research objective is to extend the \ac{ridm} with a preliminary design phase. 
+This makes it possible develop a system for a given problem or idea, using the \ac{ridm}.
+Based on the waterfall model as described by \ac{se}, the steps for problem description, requirements, and initial design were prepended to the \ac{ridm}.
+
+% Reflect: Refine the RIDM to make the execution of the different design steps explicit and unambiguous.
+The second research objective is to refine the \ac{ridm} to make the execution of the different design steps explicit and unambiguous.
+The \ac{ridm} specify the development cycle and the variable detail approach with enough detail, making them ready to use.
+How to define features and tests for the development cycle, were not as clearly defined.
+Two design steps are added in this thesis that describe a method to define the set of features and create a test protocol.
+Furthermore, a feature selection step is added to aid with the development.
+
+% Reflect: Develop and perform a case study that tests and evaluates the RIDM.
+The third and last research objective is to develop and perform a case study that tests and evaluates the design plan.
+The case study consists of a development that is performed according to the design plan.
+A set of requirements is made to ensure the optimal system of design.
+With this the \ac{Tweet on a Writeboard} system is chosen.
+The progress of the case study is monitored according to a list of questions.
+
+
+% Answer:  Which design techniques of the design method by Broenink and Broenink (2019) can be applied developing the physical part of CPS?
+With three research objectives fulfilled, it is possible to answer the two research questions:\\
+\emph{Which design techniques of the \ac{ridm} can be applied developing the physical part of CPS?}\\
+
+To answer this question I must put emphasis on the difference between the design and the model.
+The design is the specification of a system, it contains the plans, drawings, documentation, etc.
+A model represent portions of that design, depending on the goal purpose of the model.
+Both methods, from this thesis and the \ac{ridm}, make no adequate distinction between the design and the model.
+As the case study by \autocite{broenink_rapid_2019} is performed with existing hardware, the design is already finished.
+This highlights the shortcoming of the \ac{ridm} as it does model, and not design a system.
+
+The method in this thesis introduces additional steps to implement the design process.
+Although an initial design is produced, the design is implemented as a model.
+
+The point is, the design and the model are two separate components of the design process.
+The fact that this thesis starts with adding half a \ac{se} approach shows that the design aspect lacks in the current method.
+However, both case studies suggest that the \ac{ridm} is a good approach for implementing that design.
+
+This brings me to the last questions:\\
+\emph{Which adaptations are required to make the design method by \ac{ridm} suitable for developing the computation and physical part of CPS?}\\
+It is clear that there has to be a design process added, which must implement the different elements of a feature: component, function, requirement.
+
+% Answer: Which adaptations are required to make the design method by Broenink and Broenink (2019) suitable for developing the computation and physical part of CPS?
