Appreciative inquiry is an approach which seeks to promote improvement by identifying existing good practices and building on them rather than identifying problems and solving them. It involves:
Appreciating and valuing what is (identifying potential strengths)
Envisioning what could be (exploring what could be enabled through developing those potential strengths)
Dialoguing what should be (gaining perspectives on the benefits of utilising developed strengths for various stakeholders)
Designing what will be (planning for the development and deployment of those strengths)
