Usability Requirements for the Development and Evaluation of Mobile Groupware Systems

Usability is an important factor affecting the user's productivity. However, evaluating groupware usability is a complex task, especially in a mobile environment. In this paper a study with eight requirements to explore usability in a mobile groupware environment is presented. A prototype application was developed followed by a series of evaluations to observe the potential of the requirements. Results show that these requirements should be considered during the development of a mobile groupware in order to help designers to identify usability weaknesses in a mobile groupware.
