Both decentralisation and delegation relate to downward delegation of authority and responsibility. Under delegation, the authority is shared by the superior to the immediate subordinate. On the other hand, under decentralisation this concept is extended and the authority is distributed at not just one but multiple levels. That is, while delegation involves just two persons, i.e. the superior and subordinate, decentralisation is a wider concept of the same (delegation) where the power gets transferred to numerous levels. For example, suppose the director of an organisation delegates the responsibility of completing a task, hiring the required workers and supervising them to a project head. The project head in turn shares his responsibility of hiring and supervising the workers with the project lead. The project lead further delegates the responsibility of supervising the workers to the team lead. Thus, delegation at each level from the director, to project head, project lead and further to the team lead results in decentralisation. Hence, it can be said that delegation at each level leads to decentralisation and decentralisation is extending delegation to the lowest level.
