Organising

Organising is the management function of assigning duties, grouping tasks, establishing authority and allocating resources required to carry out a specific plan. Once a specific plan has been established for the accomplishment of an organisational goal, the organising function examines the activities and resources required to implement the plan. It determines what activities and resources are required. It decides who will do a particular task, where it will be done, and when it will be done. Organising involves the grouping of the required tasks into manageable departments or work units and the establishment of authority and reporting relationships within the organisational hierarchy. Proper organisational techniques help in the accomplishment of work and promote both the efficiency of operations and the effectiveness of results.
