This process analysis evaluates the existing GUI development and testing process of a multina- tional IT company and tries to find rooms for improvements. This company develops a program which provides a web front end for users. At the moment there are no programmatically usable style guide and no automated test cases for the GUI used. Thus to enhance the current processes we describe a set of characteristics and principles to aid in the creation of a pattern library. Additionally we evaluate several tools to support automated testing of the created components and the implementation of the product in question. Finally we show how the results can be integrated into the existing development process.
