In response to the OSTP Public Access Memo from 2013, most funding agencies require Data Management Plans (DMPs) with every funding proposal. Funders typically outline or link to their DMP requirements in their funding announcements. DMPs can play a role in a funder's award decision. DMPs have advantages beyond their role in grant awards. The development of these documents can prompt valuable communication and planning among collaborators during the early stages of a project. Later on, a DMP can provide a framework for documentation that keeps graduate students, postdocs, and collaborators aware of systematic organization, expectations, and policies. At the end of the project, everyone is more likely to be on the same page when it's time to publish a paper, submit a new grant or renewal, or write a thesis. The Research Data Service provides fast, free, and confidential feedback on draft DMPs. We work with library-based subject experts so that our feedback incorporates disciplinary and data management expertise.
