Abstract:Testing is an incredibly important part of the design process. Before a quality product is put into production, it has gone through extensive testing procedures. Likewise, new design methods have to be tested before they can be used in a design project. The RIDM is a proposed feature-based design method for rapid development of CPS. Using RIDM the system is divided into a set of features. Each feature represents a part of the system functionality. By implementing and testing one feature at the time it provides a structured method to deal with the complexity of CPS. This thesis evaluates if the RIDM is a suitable design method for the hardware-side of CPS. For the evaluation, a system is designed using the RIDM as a case study. Prior to the case study, some adaptations are made in order to use the design method for hardware. These adaptations add steps to create the set of features for a given design problem. The RIDM focusses more on how to implement the features and less on how to define the features. However, the case study showed that the method of defining features is crucially important to the outcome of the design process. Another important finding is that a feature cannot be described with functionality alone. To be able to implement and test a feature, it must describe requirements and components as well. Overall, the RIDM shows real potential to improve the design process of CPS. The approach to determine the order in which features are implemented greatly reduces the impact of design failures. Unfortunately, most of the RIDM is currently hindered due to a lack of tooling. The main findings in this thesis suggest that the RIDM must incorporate a holistic design process. This design process describes all development steps needed to get from a problem description, via the set of features, to a finalized product. Furthermore, tooling to organize and test the development is required to utilize all advantages the RIDM provides.
