Brainstorming is a creative problem-solving technique that encourages the generation of ideas in a group setting. Participants share their thoughts freely, without criticism, to explore various solutions to a specific issue. This method promotes collaboration and can lead to innovative outcomes by combining different perspectives. The process typically involves a facilitator who guides the discussion, ensuring that everyone has a chance to contribute. Commonly used in business and education, brainstorming can be enhanced through tools like mind maps or sticky notes. It is often associated with Alex Osborn, who popularized the term in the 1940s.
