IntroductionWhen it comes to organizational behavior, teams and groups are classified as the backbone of the organization because an organization that forms a team or group is likely to achieve its objectives. The reason why organizations form a team and a group is to ensure that employees influence each other to achieve a common goal. However, the use of teams and groups from a manager's perspective is intended to improve performance. Groups A group could be defined as “A psychological group is any number of people who interact with each other, are psychologically aware of each other, and perceive each other. as a group” (Schein, 1988: 1). There are different types of groups and they are formal and informal or temporary and permanent, for example: a group can be formed for an event like a jury for a court case (informal and temporary group). The formal group adopts the professional approach whereby this group forms a set of objectives and coordinates its activities in order to achieve the set objectives; whereas the informal group is composed of individuals who influence the behaviors of others and the structure of an informal group is flexible or loose (Hodgetts and Hegar, 2007; Dutt, 2008).
