Phase 3 · Challenge Brief Frames

Four briefs for the hack

Three confirmed · one open · Studio Zao for ELWA/NLWA · Sprint review 30 April

Three briefs are analytically confirmed: sized against the intervention matrix, anchored in qualitative research, and validated in stakeholder review. The fourth slot is open — a structured space to surface directions the data suggests but hasn't named. All four are starting points for ideation, not solutions.

Brief 1

Closing the selling gap

How might we make selling, swapping or routing-on a garment as frictionless as buying one — closing the gap between effortless acquisition and effortful disposal?
How to think about it
  • ›What if the effort to list a garment could be collapsed to a single photograph — AI-valued, routed instantly?
  • ›What if routing-on happened at the moment of acquisition — a forward-disposal decision made when buying, not when clearing?
  • ›What if the person receiving the garment was visible to the person selling it — closing the anonymity gap that makes charity feel abstract?
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.

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 2

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?
How to think about it
  • ›What if the clearout trigger was external and calendared — not a crisis, but a recurring neighbourhood moment?
  • ›What if the question was never "where do I take this?" but "how much is this worth?" — value as the hook, logistics as the answer?
  • ›What if the clearout was social — a shared occasion that converts the private guilt of accumulation into a collective act?
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

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.
Brief 3

Closing the information gap

How might we close the information gap at the disposal moment — about what clothes are worth, where they can usefully go, and what happens to them when they get there?
How to think about it
  • ›What if someone could know, in seconds, whether a garment was worth donating, selling, or recycling — and where the right place was?
  • ›What if the transparency of the destination changed the decision — seeing who receives it, what they pay for it, what happens to it next?
  • ›What if the value of an unworn wardrobe was made visible — not as a guilt trip, but as a genuine financial and environmental asset?
Qual anchors
“Probably should recycle it, but you can be lying if I said I did.”
James · The Pragmatic Replacer
“It would be better if we have more than boxes.”
Maryna · The Seasonal Clearer
Stakeholder TRAID and Oxfam both note that quality anxiety drives self-exclusion — donors throw away rather than donate because they assume the item won't be wanted. The gap is perception, not reality. Jose (Reskinned) flags condition transparency as an unsolved logistics problem across the sector.
Who it reaches
Primary The Accumulator 71.8% face info barrier
Primary The Ethical Keeper 54.3% face info barrier
Secondary The Pragmatic Replacer 49.5% face info barrier
Secondary The Seasonal Clearer 41.5% face info barrier
Intervention stack
Physical / Proximity Tech / Digital Values / Identity
429· 42.3% of sample
Knowledge barrier: quality, route, trust or salience
Lead signal: 34% cite quality concern as disposal barrier
~83% broadcast reachable via digital channels
Quant Medium
Stakeholder Strong
Additionality Med–high
Design constraint Information alone does not change behaviour — the sector has tried leaflets and they failed. Any solution must collapse the gap between knowing and doing. The business model must not depend on volume of information produced; it must depend on volume of garments moved.

Your brief

How might we Based on everything above — the personas, the journey signals, the overlaps — where do you see a fourth opportunity we haven't named?
Starting points to consider
  • ›Is there a moment in the journey where no brief currently has purchase? Name it.
  • ›Is there a persona whose primary barrier hasn't been addressed by any of the three briefs?
  • ›Is there a business model or sector angle that these briefs don't reach?
Open — Any brief that emerges from the session can be sized retrospectively against the persona data. Bring the idea; the numbers can follow.
Runner-up brief · held in reserve
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?
Audience: 16.1% of Londoners (163) · Physical × Habit overlap · Primary: The Accumulator, The Pragmatic Replacer
Note: Analytically strong but smaller prize. Kept as a back-pocket option if the session surfaces appetite for a third structured brief — sizing can be computed retroactively for any emerging direction.
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.
