What is the optimum group size for brainstorming?

The optimum group size for brainstorming is six to eight individuals who represent a range of backgrounds and experiences with the topic. This size is considered ideal because it allows for a diverse set of ideas and perspectives, while still being manageable enough to ensure that everyone has an opportunity to contribute. Having participants from varied backgrounds enhances the creative process by introducing different viewpoints and experiences, thereby enriching the brainstorming session and leading to a broader range of innovative solutions .
