The purpose of this exercise is to evaluate concept ideas based on criteria they should live up to. 

Accomodate participants who are not able to:

If the participants can not see the method could be performed orally although the participant will not get the visuel output but only hear what the final score was for each.


If the participant can not control their movements a documenter or other participants could lead the pen for the participant.


If the participant can not hold on to a pen the method could be read out loud or a documenter could note down what is being said.


If the participant can not speak sign language or other symbol language could be used.


If the participants can not hear sign language could be used or everything is communicated in writing.


Depending on the ability being limited according to not being able to focus because of distractions or because of time crunch – either reduce time spent or increase the time spent for brainstorming.

If a participant feels excluded or not comfortable within the assigned group try to mix up the groups.



Concept proposals and criteria the concepts should live up to.

Step by Step


1 Predefine the criteria that the concept proposals should live up to and note them on the spiderweb templates. 5 Hand out one concept proposal and one spiderweb template at a time and ask the groups to discuss the concept through and rate the concept in regards to the 1- 5 scale by filling in the template for each criteria (10 min).


2 Divide the participants in groups of 3. 6 Hand out a new concept proposal and template when the participants have filled in the first template (10 min).
3 Present each criteria and elaborate on what is meant to ensure that all participants have the correct understanding (2 min). 7 Step 6 is repeated as many times as there are concept proposals.
4 Present the scoring scale to ensure that the participants have the correct understanding (1 min).
The scale goes from 1 to 5:5 = The concept proposal lives fully up to the criteria4 = The concept proposal almost lives up to the criteria. Only minor things differentiates.

3 = The concept proposal lives somewhat up to the criteria although changes are necessary.

2 = The concept proposal needs to be changed a lot to live up to the criteria.

1 = The concept proposal does not live up to the criteria at all

When doing this method you should consider

Predefined some criteria that you know the concepts should live up to. But to engage your participants even more it can be a good idea to have them state some criteria that they have found throughout the workshop.

Although, make your participants come up with some criteria as well. This will make them feel valuable and maybe they will have important findings that you as a facilitator had not thought of.

The time depends on how many concept proposals each group should evaluate. 10 minutes should be given for each concept proposal. If the participants have to evaluate 3 concepts they should be given 30 minutes.

If you do not have too many concept proposals you could give all groups the same concept proposals to see if they score differently depending on the group rating them.

If you have many concept proposals the method could be long if all groups have to rate all concepts. Instead, hand out different concept proposals to the different groups. When the groups are presenting make the other participants ask questions and/or provide feedback if they agree/disagree on the scoring.
