Small groups permeate nearly all facets of our lives. Our families, our jobs, our courses, and our friends are all invigorated and driven by small groups of people. In this chapter we address several issues related to small-group communication. After discussing generally what small-group communication is, we turn to theories explaining concepts like leadership, group culture, and small-group decision making. The chapter concludes by discussing several processes related to small-group effectiveness: cohesiveness, use of technology, and skills used by ethical group communicators.
