Let's imagine the most amazing hamburger!


For this Stormz demonstration, we will tackle one of the toughest and biggest challenge in the world: Reinventing the hamburger!

We will do that in several steps:

  1. Generate ideas with a silent brainstorming technique
  2. Generate even more ideas with discussion, clustering and group brainstorming
  3. Vote on the most appealing ideas with the -3/+3 vote
  4. Select the top ideas
  5. Enrich ideas with the sections
  6. Evaluate ideas with the NUF test
  7. Discuss and reflect on the outcome

1. Generate ideas

Write down all your ideas!

In this step, try to imagine all the ideas that we could implement to take on the challenge.

Don't forget to follow these rules:

  • Go for quantity: write down as many ideas as possible (one card per idea)
  • Differ judgement: don't judge the relevance of your own ideas at this step
  • Encourage wild ideas: do not stick to top of the head ideas

Note, this is a silent brainstorming, you will not be able to see other's ideas.

2. Generate even more ideas

You can now see other's ideas...

Let's build on that to generate even more ideas!

  1. Discuss to clarify the meaning of the existing ideas
  2. Merge similar ideas, you can also create clusters of ideas
  3. Generate even more ideas, use the discussion or a specific idea as a springboard for another

Again, don't forget to follow the same rules as previously:

  • Go for quantity: create as many cards as possible (write one idea per card)
  • Differ judgement: don't judge the relevance of any idea at this point
  • Seek wild ideas: stretch to create wild ideas.

3. Vote on the most promising ideas

Which ideas have the most potential?

We have generated many ideas and now we want to select the ones with the most potential.

You can either give:

  • From 1 to 3 positive points to ideas with the most potential
  • From 1 to 3 negative points to ideas with the least potential


  • You cannot vote on your own ideas, that would be unfair!
  • Do not throw away wild and crazy ideas! In the final step we will enrich the selected ideas, this is why you must select ideas based on their full potential, not only on the base of what is already stated on the card.

4. Select the top ideas

Look at the bar chart and analyze the results:

  • Which ideas are we going to select for the next step (refinement)?
  • Does the final ranking make sense?
  • Is there any idea with few points that you would like to save?
  • Do we still have some wild ideas in our selection (good) or only safe ideas (bad)?

Once done, put all the non selected ideas aside and go to the next step.

5. Improve other's ideas

Polish our rough ideas into a diamond!

Think of the ideas that we have selected: how can you improve or transform the idea?

You can improve an idea by making it either :

  • more efficient,
  • more creative or,
  • easier to implement.

6. Evaluate ideas

Individually, take the time to evaluate each one of the listed alternatives along three criteria:

  • New: is it new? Is it innovative?
  • Useful: does it solve an important problem or fulfil a real need?
  • Feasible: is it feasible? Do we have the opportunity, the skills, money or time to do it?

You can rate each alternative from [0] to [9], for example for the New criteria:

  • [0] Already done, the idea has been existing since a long time...
  • [1] Not really new, some similar ideas do exist but there is also a little originality
  • [3] Quite new and might offer new possibilities
  • [9] Very innovative, totally unseen...

You can also comment on the alternative to capture your opinion.

7. Discuss and reflect on the outcome

Let's have a look at the results and reflect on it!

Do we agree on the evaluation?

Click on each alternative, and open the Rating by users:

  • Is there a consensus between us?
  • If not, why?
