This monograph identifies literature on human systems developed from the primary constructs of "task" and of "maintenance" or "relationship." It reviews definitions of leadership and team process and the use of the primary constructs in leadership literature and in team process literature. Then, the monograph systematically reviews and compares two frameworks developed on the balance of task and maintenance or relationship--the Managerial Grid (Blake and Mouton, 1978) and Situational Leadership (Hersey and Blanchad, 1982). Each review includes an overview and sections on purpose, constructs with anticipated results, related concepts, validity, recent writings, research and results, critiques in the literature, and a concluding critique. The conceptual analysis identifies questions of construct validity and invites further development of theory based on the constructs "task" and "maintenance." The monograph concludes with a summary, a chart comparison of the Managerial Grid and Situational Leadership frameworks, and a 176-item reference list. (YLB)
