Brainstorming is a technique that involves generating as many ideas as possible in a group setting, without judging or evaluating them. The purpose of brainstorming is to stimulate creativity and innovation, and to explore different possibilities and perspectives. Setting a goal for the number of ideas to be generated in a brainstorming session is not advisable, as it may actually limit the ideas that can be generated. A goal may create a sense of competition or pressure among the participants, which may inhibit their creativity and willingness to share. A goal may also cause the participants to stop generating ideas once the goal is reached, even if there are more ideas to be discovered. Therefore, it is important for Brian to not set a goal for the number of ideas the group should generate in the session, but rather to encourage them to generate as many ideas as they can.
