description: Day 2 (Tuesday) move of a Design Sprint that structures lightning demos and the four-step independent solution sketch protocol (Notes, Ideas, Crazy 8s, Solution Sketch). Each team member produces one solution sketch individually; the skill orchestrates the day but does not author the sketches themselves. Use Tuesday morning after Monday's target moment is locked. Output is the lightning demo board, sketch assignments, and the cohort of independent sketches that become Wednesday's heat-map material.

Design Sprint Sketch (Tuesday)

Structure Tuesday's solo-but-together work. Each team member, working independently and silently, produces lightning demos in the morning and a four-step solution sketch in the afternoon. The skill structures the activity; the humans produce the sketches. Wednesday's heat-map orientation depends on having a cohort of independent sketches that did NOT contaminate each other through group brainstorming.

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`.

When to Use

• It is Day 2 of the Design Sprint and Monday's Map and Target artifact is signed off.
• Each team member brings at least 3 lightning demo sources (existing products, references, analogies that bear on the challenge).
• The team has accepted the silent-independent-sketching constraint and will NOT lapse into group brainstorming.
• Sketches are due Tuesday end-of-day for Wednesday morning heat-map.

When NOT to Use

• Monday is not closed. Return to `tool-design-sprint-map-and-target`.
• The team's instinct is to brainstorm as a group. Sprint method explicitly avoids this; if the team will not commit to independent work, the sprint will not produce diverse sketches and the heat-map becomes a popularity contest.
• The sketch step is being treated as the prototype. Sketches are concept exploration on paper or Figma frames, not Thursday's working prototype.
• Sketches are due Tuesday morning. Tuesday is the full day; rushing to lunch produces sketches the team cannot read Wednesday.

What This Skill Produces

A single bundled artifact with four sections:

1. **Lightning demo board**: each team member presents 3 demos (3 minutes each); the Facilitator extracts the reusable pattern from each demo into a one-line note. Result is a board with 12-21 patterns (4-7 team members x 3 demos). 2. **Sketch assignment plan**: divide (each person sketches a different part of the target moment) or swarm (everyone sketches the same target). Default is swarm for v0.1 Design Sprints; divide is for teams running their second sprint with the same target who want to broaden coverage. 3. **Four-step sketches from each team member**: Notes (20 min reviewing Monday output + lightning demos), Ideas (20 min rough doodles), Crazy 8s (8 minutes, 8 variations of the strongest Idea), Solution Sketch (30-90 min final 3-panel storyboard-style sketch). 4. **Recruiting tracker update**: Riley (or the recruiter) confirms Friday slots; surfaces any cancellations and triggers buffer-slot activation if needed.

See `references/TEMPLATE.md` for the canonical structure and `references/EXAMPLE.md` for the Brainshelf book-catalog Tuesday artifact.

Tuesday Time Structure

The full Tuesday workshop is approximately 7 hours (09:00-12:30 + 13:30-17:00). The skill's bundled artifact emerges across the day:

• **09:00-09:15**: Welcome + Monday recap + Tuesday agenda
• **09:15-10:45**: Lightning demos (each person 3 demos x 3 min + 1 min Facilitator extraction = ~12 min per person; 4-person team = ~50 min; 7-person team = ~85 min)
• **10:45-11:00**: Break
• **11:00-11:30**: Sketch assignment plan + Notes step (each person silently reviews Monday output and lightning demo board)
• **11:30-12:30**: Ideas step (each person silently doodles ideas in their notebook or Figma frame)
• **12:30-13:30**: Lunch + (in parallel) recruiting tracker check-in
• **13:30-13:40**: Crazy 8s (8 minutes, 8 variations of strongest Idea)
• **13:40-15:30**: Solution Sketch (final 3-panel sketch; everyone silent; Facilitator times)
• **15:30-15:45**: Break
• **15:45-16:30**: Sketches collected + named + photographed for Wednesday board; sketcher attribution hidden (Wednesday's heat-map is blind)
• **16:30-17:00**: Day-end check-in; confirm sketches uploaded; confirm Wednesday morning attendance

This skill's 180-minute timebox covers the Facilitator-led portions (lightning demos + assignment + collection). The silent sketch steps (Notes, Ideas, Crazy 8s, Solution Sketch) are individual work and run in parallel; the team is together in the room (or video call) but not collaborating.

Common Pitfalls

• **Group brainstorming.** The single most common failure mode. The Sprint method explicitly forbids group sketching because it produces sketches that converge on the loudest voice, not the best idea. Facilitator's job is to enforce silence during sketch steps.
• **Sketches not concrete enough.** A solution sketch must be understandable Wednesday morning WITHOUT the arti
