Change management is a collective term for approaches to preparing and supporting individuals, teams, and organizations in making organisational change. It includes methods that redirect or redefine the use of resources, business process, budget allocations, or other modes of operation that significantly change a company or organisation.
Organisational change management (OCM) considers the full organisation and what needs to change, while change management may be used solely to refer to how people and teams are affected by such organisational transition. It deals with many different disciplines, from behavioural and social sciences to information technology and business solutions.
In a project management context, the term “change management” may be used as an alternative to change control processes wherein changes to the scope of a project are formally introduced and approved.
