The purpose of this article is to construct an integrated theoretical model for building effective teams based on a literature review guided by several research questions on all aspects of teams, team building, team member selection, team development, and theoretical constructs that affect the development of effective teams. The principal outcome of this article is a relationship model that is grounded in the teams, teamwork, and team building literature and based on several theoretical frameworks. This rigorous model may be applied consistently among human resource development (HRD) practitioners and scholars to assist them in building effective teams.
