This chapter presents supervision with the intention of strengthening good health and well-being. Supervision strategies for patients and service users and in groups amongst health professionals are described. Supervision aims to make individuals and organisations aware of the knowledge, experiences, and values underpinning their practice. This will enable them to become aware of their practical theory and increase the possibilities for change and development. Health-literate people and organisations are important for sustainable health services and in achieving Sustainable Development Goals (SDGs). Supervision is a tool for healthcare professionals to empower individuals and organisations for lifelong learning, as it enables people’s engagement in health promotion and treatment. Supervision is a valuable strategy for reaching the SDGs Good health and well-being (3) and Quality education (4).
