Design Sprint Readiness: Storevine Brief Interface Validation
Scenario
Storevine just closed a 4-week design-partner pilot (2026-06-02 to 2026-06-30) with Bayfront Outfitters and West Loop Goods. The Founding Hypothesis A1 (template fidelity) validated; A2 pricing held at the $1k MRR offered rate. But the open rate plateaued at 78% (above the 70% pre-test commit, but Mei wants 90%+) and the actionability rating averaged 3.6 of 5 (below the 4 of 5 commit). The team needs to test whether a redesigned brief interface improves comprehension and action-taking before scaling to paid customers. Mei invokes tool-design-sprint-readiness on 2026-07-01 to validate a Design Sprint week of 2026-07-13 is the right next test.
Inputs Captured
Challenge description:
Design and test a redesigned Monday brief interface (PDF + companion web page) for retail merchandisers at 5-50 store specialty retailers to determine whether comprehension of the top 3 ranked actions improves to under 5 minutes and the actionability rating reaches 4.2 of 5 (up from 3.6 in the pilot). Test through a clickable Figma prototype of the brief experience with 5 retail merchandisers Friday 2026-07-17.
Existing hypothesis:
Founding Hypothesis (2026-05-19): managed-intelligence service for 5-50 store US specialty retailers delivering Monday morning analyst-reviewed templated briefs with specific ranked actions readable in 15 minutes. Pilot validated A1 (templates produce non-generic briefs) but pilot-derived A8 added: “Brief interface design affects merchandiser comprehension and action-taking more than template content does.” A8 is the DS lead question.
Customer access status: Carlos owns recruiting; 2 slots filled by design-partner merchandisers (Bayfront + West Loop); 3 slots from his sector network (3 specialty-retail merchandisers at 8-25 store retailers in outdoor + home + specialty-food subverticals). Honorarium USD 150 per 60-min interview (B2B rate). Estimated 9 days to confirm all 5 customers.
Decider name and availability: Mei, full-week availability for 2026-07-13 to 2026-07-17; sprint windows confirmed.
Team composition draft:
- Mei (founder, PM/CEO; Decider)
- Devon (data engineering; build-feasibility check)
- Tasha (design lead; brief interface designer)
- Carlos (customer expert; ex-merchandiser at 4 specialty stores; Friday interview moderator)
Prototype medium (proposed): Clickable Figma of Monday brief delivered as PDF preview + companion web page. Tasha can build in 1 day.
Readiness Verdict: Go
The team meets all 8 canonical criteria. Pilot data makes A8 testable; recruiting is feasible via design partners + Carlos’s sector network.
| Criterion | Status |
|---|---|
| 1. Challenge sprint-worthy | PASS |
| 2. Stakes meaningful | PASS (paid-customer scale-up gates on this) |
| 3. Decider available | PASS |
| 4. Team size 4-7 | PASS (4 people) |
| 5. 5-day clearable | PASS |
| 6. Customer access | PASS (5 slots feasible in 9 days) |
| 7. Prototype medium feasible | PASS (Figma) |
| 8. Output has path forward | PASS (scale or iterate) |

Decider Checkpoint
- Mei confirms Go verdict and recruiting plan
- Mei authorizes USD 900 honorarium budget (6 slots x USD 150)
- Mei commits to Friday PM 14:00-18:00 PT Decider window for review by 17:30 PT
- Mei agrees the call will be: scale (commit to paid GA) / iterate (re-sprint brief design) / pivot (fall back to Approach 2 Pooled Analyst) / stop
Signed: Mei (founder, PM/CEO), 2026-07-01 16:15 PT.
Sprint locked for 2026-07-13 through 2026-07-17.
