Brainstorming is a creative problem-solving strategy that entails gathering a huge number of ideas in a group environment. It is a collaborative method that encourages individuals to think freely and voice their opinions without fear of being judged or criticised. The primary purpose of brainstorming is to encourage innovation, inspire new views, and develop a diverse set of potential answers or approaches to a particular problem or difficulty.

During a brainstorming session, participants suspend judgment and concentrate on quantity over quality. The emphasis is on producing as many ideas as possible, regardless of feasibility or practicality at the outset. This method supports free thought and fosters a friendly and non-threatening environment in which all views are welcomed and considered.

Establishing clear standards and creating a supportive environment are essential for conducting a productive brainstorming session. Some popular approaches used in brainstorming are:

1. Divergent Thinking: Participants are urged to think broadly and consider various viewpoints, views, and possibilities regarding the subject at hand. This allows for a diverse set of thoughts to arise.

2. Building on Ideas: Participants can expand or combine ideas suggested by others. This collaborative aspect promotes increased creativity and the development of more polished solutions.

3. Wild Ideas: Participants are urged to explore beyond normal boundaries and generate uncommon or "wild" ideas. These concepts can frequently lead to novel and unexpected solutions.

4. Time Constraints: Setting a time restriction for brainstorming sessions helps to keep focus and prevent overthinking. It encourages participants to think rapidly and produce ideas while avoiding excessive self-editing.

Following the brainstorming session, the generated ideas can be assessed, developed, and prioritized in later stages of the design or problem-solving process. Brainstorming can be an effective strategy for not just generating ideas, but also for promoting collaboration, inspiring creativity, and improving team dynamics.
