Targeted Project 4
CONGRATS: LARGE-SCALE COLLABORATION
This targeted project studies the open and large-scale community collaboration using digital platforms to create knowledge and value. It aims to provide actors (individuals–participants and project managers–teams, communities, and collectives) with tools to understand their community (information about themselves and others) and collaboration within it (activities engaged in, dynamics of collaboration, achievements). It also aims to design tools to understand how projects work and to act to improve them, based on the information received and the objectives of the actors and the project. To do this, it focuses on the study of the co-evolution of the design of platforms and the collectives that operate them, thus going beyond existing works that have either analyzed social interactions or addressed the technical challenges related to the design of platforms.
