Today software maintenance plays an important role for the success of software development projects, because existing systems have to be adapted to frequently changing needs and requirements. The concept of traceability helps to understand the development activities during the changes of a software system by linking the different artifacts via traceability links. However, traceability has to be integrated into the design methods.In this thesis the development steps of the architectural design method Quasar are evaluated. The Quasar method provides only a low support for the design of graphical user interfaces and therefore, it is extended concerning this aspect. The activities of Quasar are refined by additional activities to fill the gaps in the method and to facilitate traceability. The extended Quasar method is applied for the development of the architecture and the graphical user interface of a business information system. The design decisions in this process are described and the corresponding traceability links are established. A special emphasis while designing the user interface is also placed on the consideration of usability guidelines and principles. The extended method is evaluated during the development activities for the business information system.
