Change is underpinned by the deliberate and structured use of evidence-based methods and tools. The specific tools used depends on the context, scale and setting of the change, and are drawn from a multidisciplinary approach that blends the most appropriate tools for the specific change. Methods and tools enable understanding of the service and strategic landscape, current service provision, experience of people, organisational culture, good practice and innovation; and provide a structured approach to the planning, development, delivery and evaluation of the change.
