Why it matters
Compliments and clicks can feel like demand. Concrete behaviour gives stronger evidence and makes a small experiment possible.
Where it is used
Create an interview guide and pilot hypothesis with a target customer, evidence threshold, time limit and stop rule.
How you know you have learned it
Complete the scenario checks, explain the decision in your own words, and produce this artifact: Create an interview guide and pilot hypothesis with a target customer, evidence threshold, time limit and stop rule.

Worked example
You can spend one week testing a source-linked report service for small shops.
- Speak with a small set of relevant shop owners; record facts separately from interpretations.
- Offer the same narrowly scoped pilot to qualified buyers, explaining what they receive and when.
- Set an experiment rule in advance, such as revising the offer if no qualified buyer commits within your time budget.
- Decide from observed behaviour. A failed experiment is a reason to revise the hypothesis, not hide the result.
Your turn
A survey says people “would probably pay”. Can you forecast recurring sales from that?
Reveal answer
No. Test a concrete offer and observe actual commitment and delivery. Stated interest alone does not show purchase or retention.
Build the fundamentals behind the work
Start here for a practical offer. Use the other worlds when you want to understand models, check your numbers or build deeper expertise.
- Mathematics: percentages, costs, probability and the maths behind models.
- AI & ML: how models work, how to evaluate outputs and where they fail.
- Physics: measurement, units, energy and the physical systems behind technical projects.
