Group awareness among the members has been a concern to researchers studying the group. This paper examines benefits and impact of group awareness to members of the group work based on empirical evidence from literature on the following topics, such as Computer Supported Cooperative Work (CSCW), Computer Supported Cooperative Learning (CSCL), Human Computer Interaction (HCI), Groupware, Information Systems, Psychology, Management and Organizational Science. Systematic Literature Review (SLR) is the method employed for such review. This study contributes knowledge on group awareness and its benefits to the group by synthesising literature on group awareness for the group. Group awareness benefits the group since it enhances group performance - for instance it reduces time wastage, improves quality of output, and increases coordination.
