  • 6 templates, i.e. one for each participant, showing the focus question and 6 rows with 4 columns each
  • Mark first column with each persons name, column 2 - 4 are to capture ideas in rounds 1 - 3, etc.
  • a template can be downloaded here https://www.leanmethods.com/resources/tools-templates/brain-writing-6-3-5-template/



Number of participants: Groups of 6, or adopt the process and template to your group size

Pre-Work Required: The focus question should be clear.

Level of Difficulty to Facilitate (to be deleted during review): No specific skills required


The technique involves 6 participants who sit in a group. Each participant thinks up 3 ideas every 5 minutes.

The templates with ideas are then circulated in the group every 5 minutes, i.e. 6 rounds. Participants are encouraged to draw on others' ideas for inspiration, thus stimulating the creative process. After 6 rounds in 30 minutes the group has thought up a total of 108 ideas.

This method encourages equal participation from all team members using written rather than verbal idea generation. This technique is particularly helpful when the group is in danger of domination by certain participants or when team members may hold back because of the group makeup.


Usual or Expected Outcomes: 108 ideas for each group of 6 in 30 minutes

Recognizable components: Based on the concept of Brainstorming, the aim of 6-3-5 Brainwriting is to generate 108 new ideas in half an hour. In a similar way to brainstorming, it is not the quality of ideas that matters but the quantity.
