Within HCI task models are widely used for development and evaluation of interactive systems. Current evaluation approaches provide support for capturing performed tasks and for analyzing them in comparison to a usability experts' captured behavior. Analyzing the amount of data works fine for the evaluation of smaller systems, but becomes cumbersome and time-consuming for larger systems. Our developed method aims at making the implicitly existing expectations of a usability expert explicit to pave the way for automatically identifying candidates for usability issues. We have enhanced a CTT-like task modeling notation with a language to express expected behavior of test users. We present tool support to graphically compose expectations and to integrate them into the usability evaluation process.
