Collaborative product brief
1. Predict first
Five testers use the prototype: three cannot find booking, one asks for a purple heading, and one cannot distinguish the red/green status icons. Which two issues most directly block booking?
Change it · step through · explain
Change an input, predict what will happen, then advance one step. Read why the state changes, reset and experiment. This fixed teaching model does not save progress or award XP.

Ready to experiment
Why: Predict the first change, then advance one step.
Try this: Compare text-only with visible-and-labelled. Which barrier remains?
2. Build your procedure
Write a one-page product brief with intended users, two requirements, responsibilities, a feedback conflict and a justified revision. Define a follow-up test with an observable result.
Use AP CSP pseudocode, a language you know, or precise plain language. Your code is not executed here. Use the classroom assignment to save your response.
3. Check boundaries
| Input | Expected | Why this case |
|---|---|---|
| Colour-only status | A colour-vision access barrier remains | A label must not rely on colour alone. |
| Text/icon status but hidden booking action | The discoverability barrier remains | One revision does not resolve every requirement. |
| Visible booking action and text/icon status | Addresses both observed barriers; retest with users | A plausible revision is not proof of success. |
4. Explain and reflect
Why should a team invite someone who uses an assistive technology rather than rely only on its own members?
Model limits: The tool compares stated fictional evidence and design choices; it does not predict real usability or award points for a persuasive argument.
