An open system focuses on the throughputs that are taken from the environment. The throughputs are then given back to the environment and in this way. the open system completes its cycle.

The open system perspective plays a key role in determining the organizational effectiveness in a sense that the system receives inputs from the environment and its outputs are accepted from the external environment. The open system exchanges the feedback with the external environment of the organization, which helps the organization determine its effectiveness. The feedback, which is exchanged with the external environments, is analyzed in order to determine the changes that are needed to achieve the organizational goals and objectives. Therefore, we can say that the open system perspective is one of the integral perspectives of an organizational effectiveness because it helps the organization achieve its goals in a successful manner.

There are five basic types of behaviors included in the organizational behavior literature. The types of behaviors include task performance, organizational citizenship, counterproductive work behaviors, joining and staying with the organization, and maintaining work attendance. All these types of behaviors are of significant importance for the success of an organization.

Task performance refers to those goal-directed behaviors that are under the control of individuals. This type of behavior is used to transform the raw materials into the finished goods. If we take example of employees, we can say that employees usually have more than one dimensions for performance. In task performance behavior, all of the dimensions are analyzed in order to evaluate the employee’s performance. In my view, task performance behavior is one of the most significant behaviors because this behavior is directly related to the performance of employees.
