Abstract

While past research presents objects as essential entities in task modeling, they are in fact rarely used. In the first tool that truly considered objects, K-MADe, two main reasons may explain this limited use: an incomplete module of object description (in the tool, the expression coverage of the object concept is not wide enough) and the usability problems of K-MADe's specific interface. This paper presents a study on the object expression coverage. From case studies, we identify limitations and we infer modification on the K-MADe object entity definitions. These modifications aim to increase the expressive power of objects.
