Evaluating a MoLIC extension for Collaborative Systems design

Collaborative Systems go beyond user-system interaction, allowing users to cooperate, coordinate and communicate with each other. To support model-based design for collaborative systems, we propose an extension to the Modeling Language for Interaction as Conversation (MoLIC), allowing designers to represent user influences, cooperative tasks and awareness mechanisms to design collaboration. In this paper, we present a case study to evaluate the extended MoLIC during interpretation and design tasks performed by 12 undergraduate students. Our results point to a good acceptance of the extension, but defects introduced in the models indicate that some concepts were not very easy to understand as they were presented to participants.
