Summary documents

This section brings together the key documents that summarise the scope, direction and evidence base for DWMP28. Together, they explain how the plan is being developed, the risks it addresses, and the performance measures used to assess current and future performance.

Strategic context

The strategic context document provides an overview of DWMP28 and sets out the first stage of the process. It sets the scope, future trends and performance measures that guide the development of the full plan.
