Final Answer:
One technique to find the "things" that need to be included in the new system begins by starting with a user and the use cases and then try to identify the necessary informational "things."

This method revolves around creative and open group sessions, aiming to extract and map out essential elements that the new system must encompass. Through brainstorming, diverse perspectives and ideas are encouraged, fostering a holistic view of the required components.
