Round 1 — Pick, point, justify
For each scenario, name the most precise lens. Point to the feature that supports your choice, then state the user/task effect. You may name a plausible alternative—but you must still choose.
| Scenario | Most precise lens | Specific evidence | Effect on user/task and purpose |
|---|---|---|---|
| 1. A progress bar appears while a large file uploads. | |||
| 2. Ctrl+Z reverses an accidental deletion. | |||
| 3. Every page puts the main navigation in the same place and order. | |||
| 4. A video player offers captions and a transcript. | |||
| 5. A “Back” button is described as rangatiratanga. | |||
| 6. Search accepts kupu Māori with tohutō and returns the correct te reo content. |
Round 2 — Claim-strength pressure test
Choose: strongly evidenced, possible—more evidence needed, or better explained by ordinary HCI. Then state what makes the claim strong or what evidence is missing.
An iwi-governed archive lets the iwi set access and reuse conditions for digitised taonga.

A repairable device is labelled kaitiakitanga because it lasts longer.

A large-text setting is classified as flexibility and efficiency. Could accessibility be more precise?

My choice(s):
An app opens with a friendly greeting and is labelled manaakitanga.
My judgement:
Six-minute exam response
Choose one scenario. Analyse the feature using the most precise principle. Include the user/task, mechanism, effect on usability, effect on purpose, and one limitation or alternative lens.
Self-check before you stop
Achievement — demonstrates understanding
□ I described the interface purpose, feature and relevant principle accurately.
Merit — examines
□ I explained how the mechanism affects a named user completing a task.
Excellence — evaluates
□ I made a supported judgement using significance, suitability, trade-off, comparison or a specific improvement.
Precision
□ I considered another plausible lens and showed why my choice was stronger—or what evidence is missing.
