Phase 3 · Challenge Brief Frames

Three briefs for the hack

Qual × quant anchored · intervention-stack sized · Studio Zao for ELWA/NLWA · Sprint review 30 April

Each brief is anchored on a qualitative theme from the stakeholder and consumer research, sized against the intervention matrix, and framed as a how might we question. They are starting points for ideation, not fully-formed solutions — the design latitude is intentional.

Brief 1

The single-item route

How might we make disposing of one or two garments — at the moment a person decides they no longer want them — as frictionless as the black bin, but routed somewhere useful?
Qual anchors
“Probably should recycle it, but you can be lying if I said I did.”
James · The Pragmatic Replacer
“If it's literally on my route, otherwise no.”
Chiara · The Accumulator
Stakeholder TRAID, UKFT, UAL, and Poplar Works independently converge on the same infrastructure gap — the donation system is built for batched volumes, not single items.
Who it reaches
Primary The Accumulator physical 50.3%
Primary The Pragmatic Replacer habit 78.1%
Secondary The Seasonal Clearer habit 92.3%
Intervention stack
Physical / Proximity Habit-Building
163· 16.1% of sample
Physical × Habit overlap
Quant Strong
Stakeholder Strong
Additionality High
Design constraint The circular option must cost no more effort than the bin. Proximity is necessary but not sufficient — unconditional-acceptance messaging is required for The Pragmatic Replacer. Do not frame this as a “recycling” play.
Brief 2

Closing the acquisition gap

How might we make selling, swapping or routing-on a secondhand garment as low-friction as buying one — and close the listing-effort gap that traps inventory in young people's wardrobes?
Qual anchors
“I never really throw my clothes away before.”
Momo · The Accumulator
“I just feel like I'm giving it to an establishment.”
Lizzie · The Ethical Keeper
Stakeholder Oxfam (Vinted is normalising pre-loved), Reskinned (high-margin route exists for premium), UKFT and UAL (listing friction is the technology gap) — all converge on the effort-to-sell as the primary blocker.
Who it reaches
Primary The Accumulator peer 96.6% · tech 96.0%
Primary The Ethical Keeper values 100%
Secondary Tech-responsive Pragmatic Replacers n=112 · skews <35
Intervention stack
Tech / Digital Peer / Social
442· 43.6% of sample
Tech × Peer overlap
Quant Strong
Stakeholder Medium
Additionality High
Design constraint Must serve the post-acquisition moment — the bag that doesn't move — not the acquisition moment. Design for circular flow, not platform churn. Do not lead with identity or values framing.
Brief 3

The clearout occasion

How might we create a regular disposal occasion — seasonal, neighbourhood-linked, or calendar-anchored — that converts passive accumulation into periodic action without requiring crisis triggers?
Qual anchors
“It would be better if we have more than boxes.”
Maryna · The Seasonal Clearer
“I feel kind of shy going to the charity shop to donate.”
Karima · The Seasonal Clearer
Stakeholder Patrick (Poplar Works) testing the physical version with shopping-centre conversions; Becky (UAL) on habit-stacking with gym, laundry, school run; Jose and Ross both point to delivery-economy spare capacity as a possible collection mechanic.
Who it reaches
Primary The Seasonal Clearer habit 92.3% · 179 strong
Primary The Ethical Keeper habit 95.3% · 75 strong
Secondary The Pragmatic Replacer habit 78.1% · n=331
Intervention stack
Habit-Building Peer / Social Physical / Proximity
587· 57.9% of sample
Habit × Peer overlap
Quant Medium
Stakeholder Medium
Additionality Med–high
Design constraint The Seasonal Clearer needs occasion infrastructure, not messaging. The Ethical Keeper needs destination transparency, not frequency prompts. Same brief, two mechanisms — design for modularity.
Cross-cutting design requirements · apply to all briefs
Spec line 1
Trust transparency

Bake destination visibility into the capture moment. The trust deficit will swallow any intervention that doesn't address it. Not a separate brief — a spec line on every brief.

Spec line 2
Cultural-aesthetic fit

Whatever brief wins should not deepen the existing bin-leakage for non-Western-aesthetic items (Karima's abayas, Momo's vibrant prints). At minimum, an opt-in routing flag to community channels.
