The organisations in which mid and lower-level managers make most of the decisions is called decentralised organisation. In it higher authority is given to workers and functionaries. While in the centralised organisations all the decisions are made by the manager at the top.
All organisations are decentralised to some extent. However the extent of decentralisation differ from organisation to organisation. In strongly centralised organisations although the authority is delegated to lower-level managers they do not have much freedom to make decisions.
