Brainstorming techniques are methods used to generate ideas and solutions in a group or individual setting. Common techniques include mind mapping, where ideas are visually organized around a central concept, and free writing, which encourages spontaneous thought without worrying about structure. These methods help participants think creatively and explore various perspectives. Another popular technique is brainwriting, where individuals write down their ideas on paper before sharing them with the group. This allows for quieter participants to contribute without interruption. Additionally, SCAMPER is a technique that prompts users to think about how to Substitute, Combine, Adapt, Modify, Put to another use, Eliminate, or Reverse existing ideas.
