[Excerpt] Our objective in this chapter is to provide an integrative perspective on work groups and teams in organizations, one that addresses primary foci of theory and research, highlights applied implications, and identifies key issues in need of research attention and resolution. Given the volume of existing reviews,
our review is not intended to be exhaustive. Rather, it uses representative work to characterize key topics, and focuses on recent work that breaks new ground to help move theory and research forward. Although our approach risks trading breadth for depth, we believe that there is much value in taking a more integrative view of the important areas of team research, identifying key research themes, and linking the themes and disparate topics closer together. To the extent that we identify new and necessary areas of theory development and research, the value of this approach will be evident.
