2.5 Strengths of the current change theories
The major strengths of the current change theories obviously lies in the function of controlling the management systems of an organization and can thus be used to develop the competitive strategies according to the features of changes in the marketplace. They are of great importance in influencing the success of management (Chenhall, 2003). Usually, since business resources are very complicated, the management control also varies according to the forms of resources. As a result, in order to understand the strengths of the current change theories, it is important and necessary to clarify the function of management control systems as well as the solutions of these systems in details. Generally speaking, the strengths of the change theories at the present time are fruitful in controlling the result of management, the process of the management, the control of individual persons and the control of the whole organization in the integral level.

The control of the result usually refers to the control of the management goals within a certain period of time (Cortada, 2003). For example, in business organizations, rewarding and punishment measures are considered to be important methods to control the result of workplace management because these measures are very important in influencing the motivation of the employees and the effectiveness of the communicative strategies between the team leader and the staff members within a functional department or a specific work team. Obviously, the current change theories, by clarifying the potentials results of the changes associated with these management goals, usually focus specifically on the factors that might impact the result of the achievement of these goals. In this way, these theories will be important in guiding the actions of management toward a certain management objective (Jarillo, 19932007).

The control of the management processes (or actions) is another objective of the change theory. This can be regarded as an aspect of strength of the current change theories. The control of the management process can also be understood as the control of the management actions which involve the diversified steps of management so as to achieve the management objectives. In a certain sense, process management can be regarded as the control of the processes of the objective management of an organization. It usually ensures that the action of each staff member of an organization should be in accordance with the organization’s main management goal (Ellis, 2005). For example, the control of the individual behavior and the methodology used by leaders to motivate the staff members can both be regarded as the process control. In the major change theories at the present time, the prediction of the major factors influencing the individual performance is one of the major contents (Crockford, 1986). As a result, these theories are instructive in providing methodologies in controlling the management processes especially related to the controlling of the behavior of individual employees.

The strength of the major controlling theories is also reflected by its significance to control the individual employees according to the natural tendencies of these individuals. This will be important in choosing effective and efficient methodologies in motivating the employees with correct methodologies by the managers or the team leaders. This function of the change theories can be understood in several aspects. First of all, the change theories, by predicting the potential tendencies of individual behavior according to their particular natural tendencies, may be instructive in providing the manager with strategies to motivate the employees according to their personal goals. Secondly, these change theories, by stressing the relationship between the career development of the individuals and their personal talent, may be instructive in providing methodologies for managers to design the work for the individual employees according to their specific talents and skills. In this way, the organizational goal and the individual goal of the workers can be integrated together and thus the motivation of the staff members can achieve better result to the organizational management too.
