Centralisation
Centralisation (British), or centralization (American), is the process by which the activities of an organization, particularly those regarding planning and decision-making, become concentrated within a particular location or group, keeping all of the important decision-making powers within the head office or the centre of the organisation.
The term has a variety of meanings in several fields. In political science, centralisation refers to the concentration of a government's power – both geographically and politically – into a centralised government. In neuroscience, centralisation refers to the evolutionary trend of the nervous system to be partitioned into a central nervous system and peripheral nervous system. In business studies, centralisation and decentralisation refer to where decisions are made in the chain of command.
