look great, grow fast, don’t need much effort to take care of, they stay even after winter comes and sometimes we find them one year later slowly rotting in the fields or our gardens. Just like with . They pop-up like hiccups and they get dangerously engraved into our minds and are sometimes hard to remove.

Therefore, the purest form of applies an ancient principle of the Beginner’s mind in order to chop off all those thistles right at the beginning of the process so that the cherry-trees of Design Thinking can be truly fruitful.

### Assumption? What do you mean?

A thing that is accepted as true or as certain to happen, without proof. — Oxford Dictionary

Well, so… we are accepting something to be true without a proof. That doesn’t sound very scientific or logical. It sounds a little bit like an oxymoron. How can we accept something as true without a proof unless it’s an axiom?

Let’s take an example. So I believe that if I come home earlier, my partner will be happier. Or if I come to office earlier my manager will be happier. But is this true? Maybe.

Then what…!?

I guess somebody in the back of the meeting room raised their hand and suggested to test the assumptions to get our proof we need…

### Testing assumptions

So that people developed a method, where they test assumptions like a scientist would try to prove their hypothesis by a quantitative analysis of a sample and statistically prove that it’s (almost) true.

This is great and it works, unless we want to be really creative and come up with something radically new or we want to find out what the real root-causes of problems grounded in human needs are, rather than just scratch the surface of symptoms.

Let’s take an example. If our assumptions about a local cafeteria and its business problem of low sales of coffee are:

1. people don’t like coffee in our cafeteria
2. cleaning service in the cafeteria is poor
3. price tag of the coffee is too high
4. people prefer tea rather than coffee
5. our cafeteria is too far from their seating

What one would do is to test these assumptions and realise that assumption three as depicted below is valid because when we asked our guests in a questionnaire, 70% of them considered the price as high.
