Reorganisation is a process of restructuring an organisation in order to improve its efficiency and effectiveness. It involves changing the structure, roles, responsibilities, processes, and systems of an organisation. The term 'REFORM' is often used interchangeably with reorganisation, as both involve making changes to an organisation. Reorganisation can be done in order to respond to changes in the external environment, such as changes in customer needs or technological advances, or to address internal issues, such as inefficient processes or inadequate resources.
