This is a list I wrote when I was consulted about what tools would be good to have when holding a brainstorming session with 25 participants

  • Large Post-It (note) (e.g. 75mm x 75mm)
    • To be written and pasted on a wall to be shared by several people
    • Number of pieces to be distributed per person
      • Do not suppress opinions because others have them. Remove hurdles to expressing opinions whenever possible.
    • If you have a choice of colors, you should use a single color (yellow).
    • If you can’t choose, you can mix colors, but if you have a mix of people who make sense of the color coding and those who don’t, it puts a strain on your thinking. Discussion is necessary beforehand.
    • If color coding is to have meaning, each person must be able to use all the colors without having to wait for all the colors to be available.
  • Large post-it pens
    • Need a thicker pen, as ballpoint pens cannot be read away from the wall when it is stretched out.
    • For example, here’s one like this: https://www.amazon.co.jp/dp/B001MT8802/
    • You could use a makie, but it’s oil-based and you run the risk of it smearing on your desk.
    • At least one black should go to each person. Red and blue are better if there is room.
  • Small post-its (e.g. 38mm x 50mm)
  • Ballpoint pen for writing at hand
    • For example, here’s one like this: https://www.amazon.co.jp/dp/B001C09BS4/
    • Each person should bring a pen that he or she is comfortable with, but there may be cases where ink runs out or people want to share pens, so it is a good idea to have enough pens for everyone.
  • 1-3 100-sheet packs of A4 print paper
    • As a rich white paper.

Other things that may be nice to have but not necessary

  • Anywhere Whiteboard Sheet https://www.amazon.co.jp/dp/B004BEJ9MG
  • whiteboard marker
    • Don’t trust them even if they say they are provided at the venue, they may be out of ink.
  • clay
  • (corrugated) cardboard
  • Lego bricks
  • scissors
  • packing tape
  • masking tape
  • vinyl strap
  • splittable (wood) chopsticks
  • bamboo skewer
  • Tape measure (for measuring length)
  • Cutter knife, cutter mat
  • Colored pencils with many colors
  • double-sided tape
  • Aron Alpha
