One Idea Sprint Day 3: Build the Smallest Useful Test
Gary WhittakerOne Idea Sprint Day 3: Build the Smallest Useful Test
Build one controlled, reviewable asset that answers the uncertainty you chose—then stop and record the result.
Today’s practical job
Create one small result that answers the main uncertainty from Day 1 within the limits approved on Day 2. Bring your Sprint Flame Statement and Sprint Rock Check.
Question
Restate one uncertainty as a test question.
Asset
Choose the smallest reviewable version.
Evidence
Decide what result will actually answer the question.
Six steps for Day 3
- Restate the test question.
- Choose one test asset. One section, hook, email, outline, page block or prototype.
- Choose the review method. Target-user review, self-review criteria, technical check or approved reference.
- Define the evidence before building.
- Build within a fixed boundary.
- Record what happened.
Smallest useful test examples
Use this
- One song hook, not an album.
- One book section, not a manuscript.
- One newsletter issue, not a 12-week sequence.
- One landing-page section, not a website.
- One product outline, not a store.
Evidence should answer the question
- Can the user complete the intended task?
- Does the hook communicate the intended emotion?
- Can the visitor identify the next action?
- Can the creator complete the workflow within the limit?
- Where does the reviewer become confused?
Worked example
Test question: Can a first-time AI music creator use this one-page organizing structure without extra explanation?
Test asset: one-page guide containing project name, version, prompt/source notes, human changes and next action.
Review method: one beginner attempts to organize a sample song project.
Evidence: which fields are completed correctly, where the reviewer hesitates, and what additional explanation they request.
Boundary: 45 minutes; no course, download store or public launch.
Complete the Sprint Cycle Test Record
Record 4: Sprint Cycle Test Record
Test question: [one question]
Test asset: [one reviewable item]
Time boundary: [session limit]
Reviewer or evidence source: [who or what]
Expected result: [what would support the idea]
Actual result: [what happened]
Main lesson: [what you learned]
Unresolved issue: [what remains unknown]
Know when to stop building
Stop when the test already answers the question, the session reaches its limit, the project expands beyond the approved scope, new work no longer improves the evidence, or a new Rock issue appears.
More output is not automatically more evidence.
Day 3 completion check
- One test question
- One test asset
- One evidence source
- One recorded result
- One lesson and one unresolved issue
