# C4-1 Checkpoint โ€” Your Design Pack

The Hamilton and Alexandra College ยท Year 12 ยท 2026

The **C4-1 checkpoint** is the *design pack* you build before the Alternative Design validation. It's worth **60% of C4** and is due **T2W7**. This page tells you exactly what to produce and what separates a pass from a top band.

> Build this pack **yourself**. The validation (Alternative Design, 30 min, ๐Ÿ”’ no internet, no AI, no notes โ€” not even your pack) asks you to apply the same four ideation tools *on the spot* and critique your own choices. You can only do that if the ideation here was genuinely yours.

## What you submit
15
16
Generate design ideas using **at least three** ideation tools โ€” aim for all four โ€” plus the starting list. Commit each artefact to **GitHub** as you go, and **print the complete pack** for your portfolio.
17
18
| # | Artefact | What it is | Where |
19
|---|---|---|---|
20
| 1 | **Design-ideas list** | A rough list: what features it could have, what it could look like, how users might interact, what existing apps inspire you | โ˜๏ธ GitHub |
21
| 2 | **Mood board** | Visual look-and-feel โ€” colours, typography, UI patterns, screenshots of apps that inspire you | โ˜๏ธ GitHub |
22
| 3 | **Brainstorm** | A timed (10โ€“15 min) burst โ€” quantity over quality, no filtering โ€” then group the ideas into themes | โ˜๏ธ GitHub |
23
| 4 | **Mind map** | Your solution at the centre; branch out to feature areas โ†’ specific functions โ†’ design choices | โ˜๏ธ GitHub |
24
| 5 | **Design sketches** | 2โ€“3+ annotated screen layouts โ€” focus on layout, navigation flow, key interactions | โ˜๏ธ GitHub |
25
| โ€” | **Complete design pack** | Steps 1โ€“5 compiled and annotated | ๐Ÿ–จ๏ธ Portfolio |
26
27
Each ideation tool is a **different lens on the same design problem** โ€” not five copies of the same idea. Quick and clear beats polished: *ideas, not art.*

## Annotations are what move you up the bands
32
33
The ideation tools get you onto the ladder; the **depth of your annotations** decides how high you climb. Annotate across *all* your design work at three depths:
34
35
| Depth | What it does | Example |
36
|---|---|---|
37
| **Identify** (L5) | Name what each element *is* | "This is the search bar." |
38
| **Explain** (L7) | Describe its appearance *and* function | "The search bar sits top-right so phone users reach it with their thumb; it filters results as you type." |
39
| **Justify** (L9) | Say *why* this choice โ€” name the alternative you rejected | "I considered a bottom tab bar, but the dashboard needed vertical space, so I chose side navigation." |
40
41
The Level 9 move is the **"I considered X, I chose Y, because Z"** sentence shape. Tie every justification back to a specific **SRS requirement** or **user need**.

## What 100% looks like
46
47
Each level builds on the one below โ€” you score at the highest level where every step beneath it is clearly met:
