| 3 | # Design Sprint Test and Score (Friday) |
| 4 | |
| 5 | Friday is the sprint's payoff. 5 target-profile customers run the prototype while the team observes; the team synthesizes observations into a scorecard against the sprint questions; the Decider makes the build / iterate / pivot / stop call by end-of-day. The week's 35-40 person-days plus customer recruiting cost converts into one actionable decision. |

| 7 | Family contract: [`docs/reference/skill-families/design-sprint-skills-contract.md`](../../docs/reference/skill-families/design-sprint-skills-contract.md). This skill is a member of `design-sprint-skills`. |
| 8 | |
| 9 | ## When to Use |
| 10 | |
| 11 | - It is Day 5 of the Design Sprint and Thursday's prototype passed trial run. |
| 12 | - 5 confirmed participants are scheduled (canonical; or 4 if 1 cancelled-and-no-buffer; pause if below 4). |
| 13 | - The team can observe interviews live (in-person or via Zoom breakout room) and synthesize during the day. |
| 14 | - The Decider is present Friday PM for the post-interview review (canonically 14:00-18:00 PT window covering observation of slots 4-5 plus Decider review by 17:30 PT). |
| 15 | |
| 16 | ## When NOT to Use |
| 17 | |
| 18 | - Thursday prototype did not pass trial run. Re-run trial; if still failing at 19:00 PT Thursday, postpone Friday. |
| 19 | - Fewer than 3 customers confirmed. Per Ratified Decision 3, the canonical guidance is 5 customers; 3-4 or 6-7 gets a documented warning; below 3 or above 7 should trigger a re-decision (postpone or split testing). Note: the v0.1.0 family validator does NOT mechanically enforce these thresholds (cohort count is in the EXAMPLE artifact, not in frontmatter); enforcement is a v2.16 validator-expansion candidate. |
| 20 | - Decider unavailable for the post-interview review window. Without Decider, the day produces observations without a call. |
| 21 | - The team plans to use this skill to write the executive memo. Per Ratified Decision 4: exec memo authoring is delegated to `foundation-stakeholder-update` (existing pm-skills foundation skill); this skill produces the Decider summary only. |

| 23 | ## What This Skill Produces |
| 24 | |
| 25 | A single bundled artifact with six sections: |
| 26 | |
| 27 | 1. **Per-customer interview observation notes**: one section per customer; covers Context (Act 2) reactions, Tasks (Act 4) behavior with timestamps, Debrief (Act 5) reactions including pricing. Captured live during the day's interviews. |
| 28 | 2. **Best quotes**: 5-15 verbatim customer quotes the team flags as most signal-bearing. Used in the Decider summary and in any downstream pitch or planning artifact. |
| 29 | 3. **Scorecard grid**: rows are the sprint questions (from Monday); columns are the 5 customers; each cell is Y / N / partial / unclear with a one-line note; rightmost column is the team's day-end decision per question (Validated / Invalidated / Inconclusive). |
| 30 | 4. **Observed patterns**: 4 buckets (worked, hesitated, broke trust, unexpected) with 2-4 patterns per bucket. Each pattern names how many customers showed it. |
| 31 | 5. **Hot takes**: one short paragraph per team member capturing their personal read on Friday before group synthesis biases the read. Written silently in parallel. |
| 32 | 6. **Decider summary**: the Decider's call (build / iterate / pivot / stop / reframe) plus the highest-confidence learning, the most important revision the team would make to the prototype direction, and the next artifact the team will produce (the post-sprint deliverable). |
