Create an account for the DMP Tool (if possible through your university) and write a very brief DMP. Your plan does not need to be very detailed (for now) – the goal is to get a sense of the tool.
Go to https://dmptool.org/, click on “Get started” and select your institution on the next screen. Then click “Create New DMP” and use a template. We suggest the NSF’s Social, Behavioral, and Economic Science as a good default, but feel free to pick any funder that seems relevant.
