A methodology of Collaborative Requirements Validation in a cooperative environment

The increasing complexity of systems and the interdisciplinary necessary to their realization push the organizations to be resorted in teams and thus they must cooperate, because it seems to constitute a means to improve the quality and the time of realizing the products. In this paper, we are interested to the validation phase in the process of requirements engineering in a cooperative context. The cooperation is not a recent practice because people cooperate since always. However, the cooperation, such as it reappears nowadays, is not simply a team work, it wants to be structured and organized in order to produce better results. To this purpose we propose a methodology which presents a collaborative approach of the requirements validation process based on the concepts of competences and multi-viewpoints. The objective of this methodology is twofold; first it increases the quality of the software product (i.e. it leads to better match users' needs) and it reduces the complexity of the validation task.
