3DM refers to DDDM, which is an acronym for Data Driven Decision Making.

DDDM (3DM) is essentially a business practice that emphasizes the use of data to make better decisions. More often than not, we rely on other factors such as our “gut feelings”, or experience to tell us which way to go. While these cues do generally provide good guidance, they shouldn’t be the basis of sound decision making. Decision making should be rooted in the scientific method – gathering data, than when analyzed provides evidence for or against a certain decision.
