Final answer:
Brainstorming is the technique used to generate a large number of creative ideas from a group, commonly employed in sessions where different thoughts are quickly documented and later refined to develop feasible solutions.
Step-by-step explanation:
To generate a large number of creative ideas from a group, the technique most commonly used is brainstorming. This method involves quickly and informally generating a plethora of possible ideas. During a brainstorming session, participants are encouraged to contribute all their thoughts on the subject matter without criticism or immediate analysis, cultivating an environment where creativity can flourish.
For instance, when assigned a task, individuals or teams might list all plausible ideas on paper, merge those that are similar, and discard the less feasible ones to narrow down their options. Brainstorming alternative solutions is highly effective during the design process as it explores the widest variety of ideas, incorporates viewpoints from different sources, and selects the most promising ones for further development
