Test the Assumptions That a Larger Vision Depends On

A larger business vision usually depends on more assumptions about demand and delivery. Identify the assumptions that matter before building every feature.

A small experiment can support a long-term vision. Specify what it should reveal and how the result will affect the next decision.

Make Assumptions and Evidence Explicit

For a class-booking service, investigate whether providers list availability and whether visitors request bookings separately. Interest, a live listing, and a booking are different observations.

GOV.UK alpha uses prototypes to test important assumptions. (GOV.UK: Alpha)

Define Scope and Stopping Conditions

Test request submission and response for one type of class over a limited period. Add payment or other functions when the experiment requires them.

Define the budget, duration, records, and conditions for continuing or revising. An extension should have a specific learning purpose.

Use Results to Change the Next Step

With limited uptake, investigate reach, clarity, and need as separate possibilities. A small trial cannot establish the size of the entire market.

The recruitment website should identify the pilot, eligibility, and conditions. Distinguish available capabilities from planned ones.

Frequently asked questions

Q: Must a prototype match production quality?

A: Build for the question. A live trial still needs reliable operation and appropriate information handling within its scope.

Q: Can the trial include manual work?

A: Yes for testing value. Record its workload and estimate the cost of continuing.

Q: How many users are needed?

A: It depends on the assumption and user variation. Observing a small trial differs from estimating market size.

Q: Should I stop after a disappointing result?

A: Investigate causes and compare revisions with additional cost. Stop when the agreed stopping conditions apply.
