A new tool to prioritize ideas in brainstorms

Recently I facilitated a workshop with students working in the Disruptive Design Studio of Unilever R&D Vlaardingen (NL). Their assignment was to think of a new product. While designing the brainstorm we thought of a new tool to prioritize ideas. This tool worked well and looked fantastic too; we called it ‘the Spiderweb’. Let me share it with you.

Step 1:

Form small teams and ask them to talk about the topic and share their ideas. The ideas are summarized on post-its and shared on a flipover. Each participant can share as many ideas as they want.

Step 2:

Each individual now selects their best 2 ideas (which might be the ideas of another participant) and takes the post-its from the flipover. The other participants each choose 2 of the remaining post-its.

Step 3:

The facilitator prepares a large circle and asks the participants to place their 2 ideas randomly on the large circle line. While placing the post-its the participants explain why they think these are the best 2 ideas.

The facilitator now connects all ideas by drawing a line towards the middle point of the cirle.

Step 4:

All candidates write their name on as many post-its as there are ideas on the outer line of the circle.  Use different colours of post-its to make it look colorful.

Step 5:

The participants place 1 post-it with their name on each line of an idea indicating how important they think that specific idea is to them: middle = 1 not important, halfway the line 2 = semi-important, on or near outer circle 3 = very important. If they choose to not select one of the ideas at all, they place their name-post-its outside the circle.

Step 6:

Now take a step back and overlook the spiderweb. Discuss with the participants which ideas have more highest or lowest score, which ideas did not get post-its, etc.

If you want, you can capture the scores 1-2-3 and make a calculation which ideas scored highest in priority. The objective of the Spiderweb, however, it to have a visual view that helps the team to discuss the selected ideas.


With the new technique I’ve seen that it is a fun, colourful way of visualising ideas and it helps the brainstorming team to select and discuss the best ideas. You can use this technique also for opinions, thoughts, topics, etc.
