IA Day 19 —
Present the Intended Solution

Show the final redesign clearly, annotate the key features and communicate it as though to a third-party manufacturer.

80 minutesIA Criterion E · B2.1.15
Guiding question: Can someone understand what your redesigned product is—and why its key features matter—in two pages?01
Today’s destination

By the end of class, you should be able to…

01

Select presentation views

Choose visuals that reveal the product and key features.

02

Annotate comprehensively

Make important features interpretable in 10 words or fewer each.

03

Communicate professionally

Present as though to a third-party manufacturer.

04

Build E pages 1–2

Keep the product—not decorative layout—the focus.

Success check: Produce clear, criterion-aligned IA evidence during today’s studio block.

Criterion E · present the intended redesign03
perspective / hero
exploded / assembly
orthographic / cutaway

The guide allows appropriate visual communication methods such as perspective, exploded, assembly, orthographic, net development, cutaway and FEA. Use only the views that help explain your product.

Criterion E · visual communication06
Studio block

The mini-lesson is short. The evidence-making is the lesson.

60+minutes work
Select the strongest visuals
Use clean, high-resolution views of the intended redesign.
Lay out E pages 1–2
Aim for 2–3 meaningful images per page.
Add key-feature annotations
Prioritize usability, function, ergonomics, material and assembly features.
Manufacturer check
Ask: could a third party understand the product without my verbal explanation?

IA Day 20 — Compare the Redesign with the Existing Product

Keep the evidence chain moving: user → research → decision → test.

Curriculum alignment
Criterion E strand 1: present the intended redesign solution with annotated key features; present as though to a third-party manufacturer using appropriate visual communication methods, which may include perspective, exploded, assembly, orthographic, net development, cutaway views and FEA; approximately two A4 pages, two to three images per page; annotations no more than 10 words. B2.1.15: create virtual representations highlighting key usability features and explain how the solution meets specifications/design intentions.
