The Journal of the Brazilian Computer Society (JBCS) invites submissions for a Special Issue on Collaborative Systems. The issue will feature original, high-quality research on all aspects of the design, development, deployment, use, and evaluation of systems that support collaboration among individuals and groups.

Collaborative systems—often associated with the field of Computer-Supported Cooperative Work (CSCW)—enable users to communicate, coordinate, and cooperate effectively across distances and contexts. As global collaboration and remote work become increasingly central in professional and educational environments, the importance of innovative and inclusive collaborative technologies grows. These systems span a variety of sociotechnical domains, including work, home, education, healthcare, the arts, entertainment, and public services. This Special Issue highlights mature research addressing various challenges and opportunities in collaborative system development.
