Decentralisation is extending delegation to the lowest level Decentralisation explains the manner in which decision making responsibilities are divided among hierarchical levels. Decentralisation refers to delegation of authority through all the levels of the organisation.

Decision making authority is shared with lower levels and is consequently placed nearest to the point of action. In other words, decision making authority is pushed down the chain of command. Delegation is the process and decentralisation is the end result, e.g., If the director give the responsibility to production head to complete the target of 20,000 units and authorise him to hire the workers, production head further shares his responsibility with manager to select the worker.

Manager shares his responsibility with supervisors, who are dealing with workers, authorise them to select workers. Here, the responsibility gets distributed at every level. 

That’s why we say systematic delegation leads to decentralisation.
