Test Assumptions, Not Ideas.

Q: How do I get started with testing & experiments?

Dear Reader,

I've been talking a lot about experiments, lately, and maybe you'd like to dip your toe in the water?

There's a very important first step you should take that may not be obvious if you're new to experiments.

It's especially important to designers that fall in love with their solutions.

Test assumptions, not ideas.

Hidden beneath every idea are giant assumptions about how something will go. It turns out humans are terrible at predicting the future so we fill in the gaps with assumptions.

Testing assumptions helps us avoid confirmation bias and forces us to think critically about the details of an idea that we might skip if we're excited about an idea.

Product ideas that make sense on paper can fail if they don't understand the realities of messy humans in a chaotic world.

In design school, we are taught to follow the brief without question, but briefs are full of assumptions.

Questioning the assumptions within ideas can sometimes feel like a “buzzkill” when the team is on a creative high, but every idea is an assumption until it’s in the hands of a customer.

Because assumptions are beliefs, they’re not always easy to identify. Assumption Hunting™️ is how you find hidden beliefs within product ideas, and it’s best done with other people.

Methods like Assumption Mapping can help you identify the risks with your team.

When you're working in highly uncertain environments like on innovation teams, opinions mean nothing.

Only the evidence behind the ideas matters, and that evidence should come from the customer or research, not the HiPPO (highest paid person’s opinion).

Assumptions are everywhere, but that doesn't mean finding them will be easy.

Sometimes, you have to simulate the idea to reveal the assumption.

Paper prototypes, storyboarding, and journey mapping can also help you recognize gaps and areas where your team is making assumptions...
