SummaryThe purpose of this article is to explain how a group can become a high performance team. The aim is also to examine the impact of demographic characteristics and cultural diversity on group behavior. This article will illustrate how demographics and cultural diversity contribute to or harm high-performing teams. High-performing teams A high level of performance forms the basis of groups and teams today. High performance is a major goal for many organizations as groups and teams have become more common within organizations. High-performing teams are teams that come together for a specific, important task. For a group to become a successful team, the team must be able to use its collective skills and behaviors to become an effective model working toward a common goal. Demographics and cultural diversity greatly influence how a group becomes a successful team. Demographic characteristics and cultural diversity can impact group behavior, while contributing to or harming team performance. There is one major difference between a group and a team: responsibility. Group members are accountable to each other, but each member is held individually accountable for their own performance. In a team, all members share responsibility as a unit. “A team is a small group of people with complementary skills who actively work together to achieve a common goal for which they hold themselves collectively accountable” (Schermerhorn, Hunt, & Osborn, 2005). It is important that everyone who is part of a high performance team has the same goal and objectives. If teammates have different goals or motivations, it can be difficult for the team to be effective. Everyone on the team must trust or learn to trust each other. The collection of ideas, knowledge and experiences of different people is better than that of a single person. From problem solving to innovation, organizations have relied on high performance among groups and teams to stand out from the rest. Having a common goal will make each team member accountable for the success and failure of the team. Since each team member is accountable to the team, each member's behavior will have an effect on the team. Belonging to a team requires each member to be clear about the goals and objectives of the team and share a common vision. (Park, 2005) By doing so, a group can become a successful team. Cultural diversity and demographics are increasingly important issues in today's workplace, impacting group behavior..
