The DFG has published a revised version of its proposal for safeguarding good scientific practice.
“Universities and other research institutes wishing to apply for DFG funding must establish rules to safeguard good scientific practice at their institutions in accordance with recommendations 1 to 8 of the guidelines.”
Not because following these guidelines is important to get funding from the DFG, but because it is worthwhile to reflect one’s own research practices from a critical point of view from time to time, I recommend reading the recommendations of the guidelines!
