Stress test your solutions. Are your solutions following the principles of Universal Design, or are you leaving a market segment behind?

The overall purpose of the Principle Prompt Cards is to challenge your ideas.
The principles can be used to evaluate and reflect upon existing solution and early stage concepts for further iterations in order to accommodate a universal design process not excluding anyone.

Tips to include participants who are not able to:


If a participant(s) can not see the ability cards could be read out loud. This would probably expand the time, although it is not seen as an obstacle.


If the participant can not write or spell they could say the changes out loud instead of writing them on post-its. Instead the facilitator could write the post-its. If this is the case, the facilitator would need a co-facilitator for each group as the facilitator can not be with all groups at the same time. Furthermore, if the participants can not read the ability cards they could be explained by the facilitator for each group. This would require a facilitator for each group.


If the participant can not control movements the method could be read out loud and instead of writing down ideas a helper, documenter or the facilitator could write down what is being said.


If the participant can not hold on to a pen the same advice as for move could be given.


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


A translator or sign language can be used.


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. Or, if you as a facilitator have been quick and analysed which ability cards that are maybe not accommodated by the participants solutions you could have chosen these ability cards prior to the method and only let them focus on those instead of all ability cards.


If you see that one participant is not comfortable in the group you could try and switch up the group. If a participant is uncomfortable it can stop their creativity.

Make sure that if the journey is from the perspective of a persona that resembles a participant, don't let them be pointed out as that can make a person uncomfortable. make sure the group is diverse and representative enough.



Concept proposals


Evaluation on how inclusive/exclusive a concept proposal is.


Moderate to complex


Moderate to complex




Core abilities:

  • Needs to be capable of reflection upon the concept proposal
  • Needs to be capable of reflecting upon other examples of abilities given in the ability cards.
  • Needs to be capable of addressing what abilities the concept proposal does not live up to and create changes so that it does live up to different abilities (require complex thinking)

Step by step:

  1. Show the participants the Principle Prompt Cards, and give them a brief introduction to the cards.

  2. Divide the participants in groups of 2-3.

  3. The groups should go through the cards one by one and discuss if the concept proposal/ideas they have affects the principle stated on the cards. Ask the groups to hold on to the cards with principles not used in their current solution (15-20 min).

  4. Ask the groups to go through the Principle Prompt Cards that their design does not use and make them discuss/brainstorm how to make the concept proposal more inclusive. Write changes to the solution on post-its – one post-it pr change (15-20).

  5. Ask the participants to present their findings and new changes to their concept proposal (5 min per group).

When doing this method you should consider:

It is preferred that the groups of participants are formed based on the solution they have worked on. Do not switch up the groups if the different groups have worked with different solutions. It is a good idea to have the participants know the concept proposal really well before introducing the principle prompt cards.

More time might be needed if the concept proposals are complex and/or if it turns out that many changes have to be made in their designs.

If there is time it could be an idea to make the participants brainstorm about each princple card to let them expand their horizon of the ability before they compare their solution to the cards. This could open up their minds ensuring that they not only focus on the examples given on the principle cards but thinks beyond that. The examples on the principle cards are just examples, there are many more examples of each ability.

How the participants should brainstorm in this method is not specified but it would be preferred that you as a facilitator have determined a brainstorm method beforehand. You can either use brainstorming, brainwalking, negative brainstorming.
