Web applications are a part of our daily lives as a source of information. They support e-learning, the organisation of internal company practices, e-commerce and so on. A number of such Web applications implement electronic procedures where users with several responsibilities participate. Such electronic procedures can be described as a collaborative activity where individual user tasks play an important role in the whole process. The goal of this paper is to show that the design of Web applications supporting electronic collaborative procedures requires both modelling of individual user tasks as well as the description of the interconnection and interaction between tasks. We illustrate our approach using a case study for the Association Francophone d'Interaction Homme-Machine (AFIHM) thesis catalogue. This case study describes several design phases from requirements engineering to implementation highlighting the role of navigation models as a means to describe collaborative user interaction over Web applications.
