The very first start is thinking ....
There is also a very nice poster/workshop you can start with:
From a data inventory to a data management plan (DMP)

Here is a short description, what this is all about, in case you do the workshop:
In the Data Management Plan (DMP) workshop, participants will gain an overview of the objectives of a DMP. They will learn how to approach a research project while considering research data management and the available infrastructure at their institution before initiating a new project. This approach is practical and can be applied directly: Step 1 involves creating a Data Inventory of the existing IT infrastructure of the institution and/or the specific field of study.
Step 2 consists of translating this Data Inventory into a DMP that also addresses the specific requirements of the respective project. We will introduce the DMP tool RDMO as an example since it is used at RWTH. However, the approach using the Data Inventory and the tool is agnostic and can be adapted to different systems.
The target group is those who are just starting a research project and are now confronted with a topic like research data management.
