Change management is an approach to managing transitions in an organisation for individuals and the company as a whole.
Basically it is required when undergoing any change in a business or during a project. It can also be referred to as the controlled identification and implementation of changes in a computer system.
It involves directing the use of resources, business process, budget allocations for three aims: adapting to change, controlling change and effecting change. The organisation designs procedures for successfully coping with changes.
