Groupware and Social Dynamics analyzed past successes and failures of social technology. The authors generalized that software made for groups did not focus enough on what makes groupware effective, but instead focused on technical designs. They advocated for more attention on workplace, group needs, and user demands. The eight problem areas of groupware were disparity…

The eight problem areas examined were; the disparity between who does the work and who gets the benefit, critical mass and prisoner’s dilemma problems, social, political and motivational factor,…
