The automotive industry is experiencing a rapid increase in software complexity due to various functionalities introduced into modern vehicles. Companies use software development standards like AUTOSAR to develop the application layer software independent from the hardware. Development methodologies such as Model-Based Design are used to increase the efficiency of the development process and decrease the time to market. However, to ensure high-quality software standards such as A-SPICE are imposed on the companies. Conforming to A-SPICE requires having certain traceability between work artifacts. Thus, manual and inefficient development, testing, and requirement management processes lead to higher time to market. This thesis will introduce the concept of virtual validation using VEOS virtual platform from dSPACE. The new toolchain will focus on automatizing the testing process, requirement management, and report generation. To highlight the benefits of the virtual validation concept this new approach will be compared to the existing one, which includes a lot of manual development steps. Besides the application of the virtual validation with AUTOSAR and non-AUTOSAR software architectures will be discussed.

The aim of this thesis is to redesign an interactive system “Arngren website” (https://arngren.net/), based on usability evaluation. Survey is used to perform the evaluation of the website to identify the usability problems. Based on the results obtained in the evaluation process, better suggestions are given to redesigning the interactive system’s user interface by applying Human-Computer Interaction (HCI) design principles. Prototyping method is used to redesign the interactive system. After redesigning the existing website, it is also subjected to the survey and results are presented in the report.
