Distinguish usability evidence from a functional failure
See this course’s project requirements
Review the Room Picker simulation from initial contract through a verified rule repair.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Define scope and observable acceptance criteria.
- Record eight diverse cases with expected and observed outcomes.
- Write a minimal reproducible bug report with impact.
- Show a one-change repair experiment and relevant comparisons.
- Deliver retest evidence and a usability hypothesis with honest limits.
Review and revise
Use these criteria to check your work and choose what to improve.
- Coverage: cases represent relevant classes and boundaries.
- Reproducibility: state, steps and results are sufficient to repeat.
- Reasoning: the repair follows evidence and preserves valid behavior.
- Handoff: claims stay within the observed version and scope.

The idea in everyday life
Functional checks ask whether the product does what its specification says. Usability observations ask whether people can understand and complete the task. Accessibility evaluation adds further perspectives and should include relevant users where possible. Here you will analyze invented observation notes, clearly labeled as synthetic, without recruiting participants or pretending a classroom simulation represents real users.
A product can follow its rules and still make the user’s task difficult.
One step at a time.
Use the sample or information you have permission to use. Keep your work as you go. You can pause between steps.
- 1
Use the supplied fictional task: "Choose two places for Cedar and check the details without confirming." The v2 button still reads "Next" and opens the Review screen, where a separate Confirm button appears.
- 2
Read three invented observations, also called synthetic observations: tester A pauses at Next; tester B clicks it but worries a booking was sent; tester C reaches Review and completes the task. Record their actions before explaining why.
- 3
Classify the issue as uncertain action meaning rather than a proven booking failure. All three can reach Review, but two notes show uncertainty about whether Next commits the request.
- 4
Propose changing Next to "Review selection" and adding "You will confirm on the next screen." Preserve the no-real-booking explanation for the practice flow.
- 5
Write a future evaluation question: can a reader predict what this button does before activating it? Label the evidence synthetic, and describe a consent-based user review as optional later work rather than completed research.
See how it works.
Fictional observation table: A waits eight seconds, saying "Will this book it?" B presses Next, then returns to inspect whether a confirmation occurred. C reads the Review screen and stops as requested. None of these notes proves that a real booking happened. They suggest that the action label does not make the next state clear. The proposed label "Review selection" states the immediate action, while a brief instruction clarifies that confirmation comes later. This is a hypothesis for further testing, not a claim that three invented testers represent all users or all accessibility needs.
Did you cover these?
- All observations are labeled synthetic.
- Functional and usability findings are distinguished.
- The proposed improvement has a future evaluation question.
What to finish
An observation-to-hypothesis note and one clearly testable wording improvement.
Watch for this
Treating synthetic observations as completed user research or equating hesitation with user incompetence.
How can I tell I understand it?
Separate observed action, inferred difficulty and proposed change.
