INTRODUCTION
1.1 BACKGROUND OF STUDY
Every organization has objectives which has been u to achieve a goal. These objectives are identified through planning. This is simply became through planning management. Of organizations establish means of achieving objectives invariably, establishing a means for achieving these objectives becomes the prior occupation for management.

This bring them face to face with a major management function which is organization. The organization process is mainly aimed to achieve co-ordinate through the design of structure of task and authority relationship.

Meanwhile, the level of objective attainment generally determiner the extents of management effectiveness. On the other hand, structure being a direct result of management function of organizing is the framework through which an organization accomplishes the task and responsibilities needed to attain its objectives. This may be why Donnelly et al stated that “structure is a means for achieving the goal established planning. Coming to the task that structure in the present day organization present complex relationship, is the need for people to organize their efforts on, later to attain certain objectives becomes more and more imperative. Hence organization structure defines the format allocation of work roles to identify the members to the organization. It establishes the line of authority for integrating and co-ordination activities. According to Gabraith and Nathan son, organizational structure means. “The organization of work into roles such as production, financial, marketing and so on. The recombining of roles into department or division around function and product, region or market and the distribution of power across the structure.

We can therefore describe the functional structure in terms of dividing tasks jobs and delegating alternatives thus these provides some aspect of major challenges faced by management, management is expected to make the appropriate analysis that will help in designing of an effective organizational structure for any total organization. A sound organizational structure activities to be directed, mottling, coordinating and control, in the overall outset of an organization and its members.
Therefore it becomes a sanctioned network of interaction and relationships between position, therefore functions and occupants and also a means through which management attempt to achieve organizational goals. The foregoing emphasis the fact that structure is the result from organizational design. It could therefore be regarded as a come variable guide without which a managerial team will not function effectively. Thus, it is far from surprise that it has been the subject of intensive study for has been adopted in trying to design effective organization structure. Firstly it was the classical theorists who passed the ideal of “one best way for structuring effectively organization. Unfortunately the answer provided by the decades of systematic research has proved this nation wrong organizations falls such a wide range of internal and external conditions that there cannot be a single structure or design that will prove successful for all. Thompson, has confirmed that ideal of stating that, The best organizational structure is the one that test for the from situation at moment. As this basic fact has become increasingly apparent, a new perspective on organizational design known as the contingency approach has taken forms. Supports of this approach reasons that there is, in fact no best singe structure. People and environment in the above factor function with the key dimensions of organization structure, which include departmentation. Chain of commands span of control centralization cons version staff complexity. The above facts, present a lot of challenges for modern managers. Prescribing a successful organization at structural agreement not only with the external environment. Unless, researches are therefore carried out I order to involved radiated recommendations are effective in practice, to that extent could management of such organization achieving their objective.
