This is a report, commissioned by the UK Commission for Health Improvement (CHI) in March 2003, which provides a literature review looking at the sharing of learning in different sectors. A key aim of CHI’s approach is to encourage NHS organisations to embed learning in their work to help them improve their practice. The report draws on studies in the fields of education, psychology, organisational learning, personal learning, and participatory approaches to explore understanding of good learning practice. It includes more than 15 case studies that illustrate methodologies and approaches used to share learning in the business, public, and voluntary sectors, paying particular attention to the types of processes that encourage engagement with diverse communities of interest or multiple stakeholders
