The present work deals with the optimization of the website of "VSZ OW/NW" (Verkehrssicherheitszentrum Obwalden/Nidwalden) which is available at www.vsz.ch. The "VSZ OW/NW" receives constantly various requests through different channels, such as telephone and e-mail, because the desired information cannot be found on the current website. The project aims to minimize these occurring problems through an adequate information architecture and also to improve the user experience on the website.

The first step was to analyze the website. The analysis included several parts, on the one hand the general structure of the website had to be understood and on the other hand the points to be improved had to be defined in a requirements definition.

This was followed by the second and most comprehensive phase of the project, prototyping and testing. The final product is this documentation and the final prototype that resulted from the numerous tests and optimizations. First, a simple prototype was created by the team. This was then tested with the help of various test persons and two further prototypes were created individually. These two variants were then presented to the responsible persons at the VSZ, from which the best characteristics could be selected, which were incorporated into the final prototype.

The thesis also discusses the methodology used, i.e. the process model. In addition, the entire project process is critically reflected and findings and problems encountered are highlighted. Finally, an outlook is given on what can be done in a next step in relation to the work done.
