specific aspects related to task accomplishment Team cohesion is viewed as a general indicator of synergistic group interaction—or process. Furthermore, cohesion has been linked to greater coordination during team-tasks as well as improved satisfaction, productivity, and group interactions. Team efficacy refers to team members' perceptions of task-specific team competence. This construct is thought to create a sense of confidence within the team that enables the group to persevere when faced with hardship. According to Hackman (2002), there are also 5 conditions that research has shown to optimize the effectiveness of the team: Real Team – Stability in the group membership over time Compelling Direction – A clear purpose that relies on end goals Enabling Structure – The groups dynamic must be producing good, not bad Social Support – The group must have a system to collaborate properly Coaching – Opportunities for a coach to give help The Aristotle project, a multi-year initiative by Google Inc. aimed at defining the characteristics of an ideal team in the workplace, has found somewhat similar conditions for group effectiveness. They found that by far, most important factor is psychological safety. The other key factors in productivity are dependability, structure and clarity, personal meaning, and each team member feeling like they have an impact. Work teams Work teams (also referred to as production and service teams) are continuing work units responsible for producing goods or providing services for the organization. Their membership is typically stable, usually full-time, and well-defined. These teams are traditionally directed by a supervisor who mandates what work is done, who does it, and in what manner is it executed. Work teams are effectively used in manufacturing sectors such as mining and apparel and service based sectors such as accounting which utilize audit teams. Self-managed work teams Self-managed work teams (also referred to as autonomous work groups) allow their members to make a greater contribution at work and constitute a significant competitive advantage for the organization. These work teams determine how they will accomplish the objectives they are mandated to achieve and decide what route they will take to complete the current assignment. Self-managed work teams are granted the responsibility of planning, scheduling, organizing, directing, controlling and evaluating their own work process. They also select their own members and evaluate the members' performance.
