How I understand it.
Every strategy rests on assumptions about customers, competitors, technology and the wider market. Choose a few whose failure would change your plans and give them recurring attention in management discussions. Invite observations from people close to customers and daily work, including evidence that challenges senior leaders. Record what you expect, run a bounded experiment and compare the result with that expectation. Surprises can reveal customer needs or operating limits that the plan missed. Diagnose disappointing results: the offer, execution, timing and test conditions may each matter. Examine promising results too, since temporary conditions can make a weak idea look strong. End each review with an experiment, a revised commitment or a decision, and assign an owner. Preserve the original assumptions so later outcomes can be compared with what the team actually believed.
03 · A fictional example
Put it into a business.
A furniture retailer tests evening consultations for city customers. Bookings stay low, but several visitors ask for remote advice during lunch breaks. The team records that surprise and runs a small lunchtime video trial. It measures attendance, purchase rate and staff time. Stronger results lead to another trial before the retailer funds a wider launch across the region.
