Each week of 2017 we present an English idiom.
"to get/start the ball rolling": to begin something such as a task, project or discussion; den Ball ins Rollen bringen
Example 1: We need to get the ball rolling on the IT project as soon as possible.
Example 2: Let's take a few minutes to brainstorm and see what we can come up with. Adam, would you like to get the ball rolling?
