This booklet provides ways for organizational team leaders to assess their team's effectiveness at regular intervals and to monitor their team's performance. The booklet identifies six key aspects, or dimensions, consistent across all teams. If all six dimensions are strong within a team, the team has the means to conduct its work and perform effectively. The six dimensions are as follows: (1) a clear purpose; (2) an empowering team structure; (3) strong organizational support; (4) positive internal relationships; (5) harmonious external relationships; and (6) efficient information management. The booklet also marks four indicators of team effectiveness that signal when a problem exists along any of the six dimensions. The four indicators are the team's effort, the team's knowledge and skills, team tactics, and group dynamics. The four indicators and six dimensions are not only discussed but also presented in the form of a team-performance assessment tool. (Contains a short list of suggested readings.) (WFA)
