For which purposes it is used

Brainwriting can be useful in the following circumstances:

• Your group is too large for effective brainstorming.  You could conduct brainwriting at a 500-person conference by placing a large card on each seat, asking a question, and then having each audience member pass a card to someone else, repeating three times for a minute of writing.
• You have quiet members of your group who are intimidated by traditional brainstorming techniques.
• You work in a culture where discussing “crazy ideas” or expressing opinions that differ from those of traditional people is frowned upon.  It is beneficial when new and inventive problem-solving ideas are permitted and required.
• You don’t need a lot of time.  With the traditional number of participants – 6, for example – you can generate up to 108 new ideas in about 30 minutes.
• You don’t need special skills to facilitate.  Contrary to popular belief, brainstorming is difficult to master.  Brainwriting, on the other hand, necessitates the ability to ask a question, read a clock, and collect responses.
• You are concerned about people who are loud or pushy influencing others, as they might in traditional brainstorming.  635 allows everyone to focus quietly, which provides a less stressful environment for introverts than typical brainstorming sessions.
