Review access before testing
See this course’s project requirements
A product design case study with a need brief, concept comparison, prototype, access review, simulated usability log, and evidence-linked revision.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A product-need brief with simulated observations, a task-centered statement, constraints, and a success measure.
- A three-concept comparison with a selected prototype, two decision criteria, and a switching condition.
- A versioned low-risk reminder prototype with fictional content, a text description, and a core task sequence.
- An access-review note with three corrected barriers, a text alternative, and explicit untested areas.
- A neutral usability script and simulated observation log with a 60% unassisted completion result and issue notes.
- A product design case study with a three-version history, evidence-linked changes, and an honest next-test plan.
Review and revise
Use these criteria to check your work and choose what to improve.
- Need and concept reasoning: distinguishes simulated observations from assumptions and compares three functionally different concepts against the same task and constraints.
- Prototype and access continuity: preserves the fictional content across named versions, documents obvious access improvements, and distinguishes paper review from untested digital behavior.
- Test integrity: uses a neutral voluntary test script, keeps assisted completion separate, computes three of five as 60%, and labels the records simulated rather than customer research.
- Evidence-linked iteration: connects each Version 2 change to a specific tested issue, preserves the version history, and states that the revision still needs a new test.

The idea in everyday life
People interact with information in different ways. A reminder can fail because text is hard to read, meaning depends only on color, wording is unclear, or a digital control cannot be reached with a keyboard. Review obvious barriers before inviting anyone to test. The supplied practice can be completed alone and does not simulate or claim another person’s disability experience.
Access review and user feedback complement each other; neither is a universal guarantee.
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
Read the prototype for meaning without relying on color or decorative elements. Identify every place where a label, instruction, or location depends on a symbol or abbreviation that the case has not explained.
- 2
Revise three obvious barriers using text labels, clear language, readable presentation, and a text alternative. Keep the underlying fictional return details unchanged so later comparisons address design rather than different content.
- 3
Record what you checked and what is still untested. For a digital idea, list questions about keyboard use and assistive technology, such as screen readers. A paper prototype cannot show whether those features meet technical standards.
- 4
Plan how varied feedback could be gathered respectfully in a future real project, including accessible materials and voluntary participation. For this course, use the supplied barrier list and never require a participant to disclose disability or imitate another person’s experience.
See how it works.
Fictional practice: Version 1 contains the correct date and spelled-out location, but its visual review finds small decorative lettering, faint gray text, and crowded date and location fields. Dev uses larger plain type, darker text, and more space between fields. The labels “Return by” and “Return to” remain, and Dev keeps the selectable text description from Lesson 3. These presentation changes form Version 1.1 for testing. A future digital version would require keyboard and appropriate standards checks; a paper sketch cannot demonstrate those features. Dev records the three corrected barriers and does not claim that this review establishes accessibility for everyone.
Did you cover these?
- Meaning does not depend only on color
- Readable type, contrast, and field spacing are reviewed
- The review states scope and untested features
What to finish
An access-review note with three corrected barriers, a text alternative, and explicit untested areas.
Watch for this
Calling a design universally accessible after a checklist or one person’s feedback.
