The primary purpose of this study was to provide an analysis of the effectiveness of leadership through the interpersonal relationship between a team leader and a team. This research paper attempted to define "how" leaders create and handle effective teams. Specifically, this study was focused on UXO teams in a UXO environment performing a UXO clearance project still in progress. It was the aim of this study to provide information that will be beneficial to team leaders and will contribute to improvement of UXO team leadership techniques. METHOD: This research evaluated the relationship between the leadership demonstrated by team leaders and the effectiveness and productivity of the teams. Adoption and use of Frank LaFasto and Carl Larson s (2001) six key dimensions (focus on the goal, ensure a collaborative climate, build confidence, demonstrate sufficient technical know-how, set priorities, and manage performance) provided the basis for this study. Frank LaFasto, Ph.D. and Carl Larson, Ph.D. developed the survey instrument adopted for this study, known as the Collaborative Team Leader Instrument, from an evaluation of approximately 600 team leaders and measures team leader effectiveness across the six key dimensions.
