This document provides an overview of creating a data management plan (DMP). It discusses what a DMP is, the benefits of creating one, and what funders require. A DMP defines what data will be collected, documented, stored, shared, and preserved. Developing a DMP helps avoid problems and ensures data are reliable and secure. The document outlines six key themes a DMP should address: data types and standards, ethics, access and sharing, storage, preservation, and resources. Support is available to help researchers develop effective DMPs.
