Change Models: 

• A change model is a structured framework or theoretical model that provides guidance on how to manage and implement change within an organisation.

• Change models typically outline the stages or steps involved in the change process, providing a roadmap for understanding and managing change effectively.

• Examples of popular change models include Kotter's 8-Step Change Model, Lewin's Change Management Model (Unfreeze, Change, Refreeze), and the ADKAR model (Awareness, Desire, Knowledge, Ability, Reinforcement).

​

Change Approaches:

• A change approach refers to the specific strategy or method used to implement change within an organisation.

• While a change model provides a broad framework, a change approach is more focused and tactical, detailing the specific actions, techniques, and tools that will be used to drive change.

• Change approaches can vary depending on factors such as the nature of the change, organisational culture, resources available, and the preferences of the change agents involved.

• Examples of change approaches include participatory change, top-down change, incremental change, radical change, and continuous improvement approaches like Lean or Six Sigma.
