# Design Sprint Framework
A five-day process for answering critical business questions through design, prototyping, and testing ideas with customers. Developed at Google Ventures and used by Google, Slack, Airbnb, and hundreds of startups.
## Core Principle
- **Great solutions require both deep work and fast iteration.** The Design Sprint compresses months of debate, design, and testing into a single week, creating focus and urgency that eliminates endless discussion.
-
- **The foundation:** Traditional product development wastes months building the wrong thing. Design Sprints de-risk product decisions by testing with real users before writing production code.
+ **Great solutions require both deep work and fast iteration.** The Design Sprint compresses months of debate, design, and testing into one week, replacing endless discussion with focus and urgency. It de-risks product decisions by testing with real users before any production code is written.
## Scoring
- **Goal: 10/10.** When planning or executing a Design Sprint, rate it 0-10 based on adherence to the principles below. A 10/10 means proper structure, time-boxing, prototyping, and user testing; lower scores indicate skipping steps or insufficient testing. Always provide the current score and specific improvements needed to reach 10/10.
+ **Goal: 10/10.** Rate any sprint plan or execution 0-10 against the principles below: proper structure, time-boxing, prototyping, and user testing. Lower scores mean skipped steps or insufficient testing. Report the current score and the improvements needed to reach 10/10.
## The 5-Day Sprint Process
```
Monday → Tuesday → Wednesday → Thursday → Friday
Map Sketch Decide Prototype Test
```
- **Prerequisites:**
- - **Big challenge:** Important problem worth a week's focus
- - **Right team:** Decision maker + 4-7 people with diverse expertise
- - **Time commitment:** 5 full days (10am-5pm), no interruptions
- - **Space:** Dedicated room with whiteboards
-
- **Sprint Master:** One person facilitates, keeps time, manages energy.
+ **Prerequisites:** a big challenge worth a week's focus; the right team (Decider plus 4-7 people with diverse expertise); five full days (10am-5pm) with no interruptions; a dedicated room with whiteboards. One **Sprint Master** facilitates, keeps time, and manages energy.
## Monday: Map
**Goal:** Understand the problem and choose a target for the week.
### Morning: Start at the End
- **Exercise: Long-term goal**
- - Write the sprint question: "What do we want to be true in 2 years?"
- - Example: "Customers use our product daily" or "We've captured 20% market share"
-
- **Exercise: Sprint questions**
- - List obstacles and unknowns as questions
- - Example: "Will customers trust us with payment info?" or "Can first-time users figure out the interface?"
-
- **Format:** Write on whiteboard, entire team contributes
+ - **Long-term goal:** Write the optimistic answer to "What do we want to be true in 2 years?" — e.g., "Customers use our product daily."
+ - **Sprint questions:** List obstacles and unknowns as questions on the whiteboard, whole team contributing — e.g., "Will customers trust us with payment info?"
### Afternoon: Map the Challenge
- **Exercise: Map the customer journey**
- 1. List actors (different types of customers/users)
- 2. Draw the journey from start to finish (left to right on whiteboard)
- 3. Keep it simple: 5-15 steps max
- 4. Example: "Hears about product → Visits site → Signs up → First use → Becomes regular user"
-
- **Exercise: Ask the Experts**
- - Interview team members with specialized knowledge
- - CEO, designer, engineer, customer support, sales
- - Take detailed notes on whiteboard
- - Capture "How Might We" notes (HMW)
-
- **Exercise: How Might We (HMW) notes**
- - Rephrase problems as opportunities
- - "Customers don't understand pricing" → HMW make pricing immediately clear?
- - Write each HMW on a sticky note
- - Vote on best HMWs, organize on map
+ - **Customer journey map:** List the actors (customer types), then draw the journey left to right in 5-15 steps: "Hears about product → Visits site → Signs up → First use → Regular user."
+ - **Ask the Experts:** Interview teammates with specialized knowledge (CEO, design, engineering, support, sales); capture notes on the whiteboard.
+ - **How Might We (HMW):** Rephrase problems as opportunities — "Customers don't understand pricing" → "HMW make pricing immediately clear?" One per sticky note; vote and organize the best on the map.
### End of Day: Pick a Target
- **Exercise: Choose the target**
- - Which part of the map (customer journey) will you focus on?
- - Where's the biggest risk or opportunity?
- - Example: "We'll focus on the first 10 minutes after signup"
-
- **Decider:** The person with authority makes the final call.
+ Choose which customer and moment on the map to focus on — the biggest risk or opportunity (e.g., "the first 10 minutes after signup"). The **Decider** (person with authority) makes the final call.
- **Monday output:**
- - Long-term goal
- - Sprint questions
- - Customer journey map
- - Expert insights
- - HMW notes organized
- - Target customer and moment
+ **Monday output:** long-term goal, sprint questions, journey map, expert insights, organized HMW notes, target customer and moment.
See: [references/monday.md](references/monday.md) for detailed Monday exercises and facilitation.
## Tuesday: Sketch
- **Goal:** Generate solutions. Each person sketches a detailed solution.
+ **Goal:** Generate solutions — each person sketches a detailed solution.
### Morning: Lightning Demos
- **Exercise: Find inspiration**
- - Look at competitors and analogous products
- - 3-minute demos: "Here's what I found, here's why it's interesting"
- - Capture good ideas on whiteboard
- - Don't limit to your industry—borrow from anywhere
-
- **Exercise: Divide or swarm**
- - Divide: If map has multiple parts, different people tackle different sections
- - Swarm: If one critical problem, everyone tackles the same thing
- - Most sprints = swarm
+ - **Find inspiration:** 3-minute demos of competitors and analogous products ("Here's what I found, here's why it's interesting"); capture good ideas on the whiteboard. Borrow from any industry.
+ - **Divide or swarm:** Split the map between people if it has multiple parts; otherwise everyone tackles the same critical problem (most sprints swarm).
### Afternoon: The Four-Step Sketch
- **Goal:** Everyone individually sketches a detailed solution (not as a group!)
-
- **Step 1: Notes (20 minutes)**
- - Walk around room, review map, HMWs, inspiration
- - Take notes silently
-
- **Step 2: Ideas (20 minutes)**
- - Rough doodles, mind maps, stick figures
- - Quantity over quality
- - Still working alone
-
- **Step 3: Crazy 8s (8 minutes)**
- - Fold paper into 8 sections
- - Sketch 8 variations in 8 minutes (1 minute each)
- - Forces you past first idea
- - Can be 8 variations on one idea or 8 different ideas
-
- **Step 4: Solution Sketch (30-90 minutes)**
- - 3-panel storyboard showing customer experience
- - Step 1 → Step 2 → Step 3 (beginning, middle, end)
- - Make it self-explanatory (someone should understand without you explaining)
- - Use text, arrows, simple drawings
- - Give it a catchy title
- - **Anonymous:** Don't put your name on it
+ Everyone sketches alone — **no group brainstorming**. Individual work produces better, more diverse ideas.
- **Critical:** No group brainstorming. Individual work produces better, more diverse ideas.
+ 1. **Notes (20 min):** Silently walk the room reviewing the map, HMWs, and inspiration.
+ 2. **Ideas (20 min):** Rough doodles, mind maps, stick figures — quantity over quality.
+ 3. **Crazy 8s (8 min):** Fold paper into 8 panels and sketch 8 variations in 8 minutes — forces you past your first idea.
+ 4. **Solution Sketch (30-90 min):** A 3-panel storyboard of the customer experience (beginning, middle, end). Make it self-explanatory, give it a catchy title, and keep it **anonymous**.
- **Tuesday output:**
- - Each person has a detailed solution sketch
- - Sketches are anonymous and self-explanatory
+ **Tuesday output:** one detailed, anonymous, self-explanatory solution sketch per person.
See: [references/tuesday.md](references/tuesday.md) for sketching templates and examples.
## Wednesday: Decide
**Goal:** Critique solutions and choose the best one to prototype and test.
### Morning: Sticky Decision
- **Exercise: Art museum**
- - Tape solution sketches to wall
- - Give everyone dot stickers
- - Silently review sketches (no talking!)
- - Put dots next to interesting parts
-
- **Exercise: Heat map review**
- - Discuss each sketch for 3 minutes
- - Facilitator narrates: "Here they see X, then click Y..."
- - Sketcher stays silent (don't reveal yourself yet)
- - Team calls out interesting parts
- - Scribe captures standout ideas on whiteboard
-
- **Exercise: Straw poll**
- - Each person votes for one solution (put one large dot)
- - Explain your vote in 1 sentence
- - This is non-binding, just to see preferences
-
- **Decider:** Person with authority gets three large dots (supervote). Their decision wins.
+ - **Art museum:** Tape sketches to the wall; review silently (no talking) and mark interesting parts with dot stickers.
+ - **Heat map review:** Discuss each sketch for 3 minutes — the facilitator narrates while the anonymous sketcher stays silent; a scribe captures standout ideas on the whiteboard.
+ - **Straw poll:** Each person votes for one solution with one sentence of rationale (non-binding).
+ - **Supervote:** The Decider gets three large dots; their decision wins.
### Afternoon: Rumble or All-in-One
- **If multiple winners:**
- - **Rumble:** Competing prototypes (test different approaches)
- - **All-in-One:** Combine best ideas into one prototype
-
- **Most sprints:** All-in-one (simpler to prototype and test)
-
- **Exercise: Storyboard**
- - Draw 10-15 panel storyboard (comic book style)
- - Each panel = one screen or step
- - Opening scene: How customer discovers you
- - Middle: Your solution in action
- - Ending: Successful outcome
- - Include just enough detail for Friday's prototype
+ If multiple sketches win, choose: **Rumble** (competing prototypes testing different approaches) or **All-in-One** (combine the best ideas into one prototype — simpler, and what most sprints do).
- **Storyboard rules:**
- - Keep it simple
- - Use stick figures
- - Words and arrows okay
- - Get specific about UI
- - 10-15 panels max
+ - **Storyboard:** Draw a 10-15 panel comic of the test experience: opening scene (how the customer discovers you) → your solution in action → successful outcome. Keep it simple — stick figures, words, arrows — but get specific about the UI. Include just enough detail for Thursday's prototype.
- **Wednesday output:**
- - Winning solution(s) chosen
- - Detailed storyboard ready to prototype
+ **Wednesday output:** winning solution(s) and a detailed storyboard ready to prototype.
See: [references/wednesday.md](references/wednesday.md) for decision exercises and storyboard templates.
## Thursday: Prototype
- **Goal:** Build a realistic facade. You need something to test on Friday.
-
- **Prototype mindset:**
- - Fake it
- - Prototype only what you'll test
- - Goldilocks quality: not too high, not too low (realistic enough to get honest reactions)
- - One day only
+ **Goal:** Build a realistic facade in one day — you need something to test on Friday.
- **Prototype fidelity:**
- - **Too low:** Sketches, wireframes (customers can't react realistically)
- - **Too high:** Working code, pixel-perfect design (wastes time)
- - **Just right:** Looks real, doesn't work real (facades, click-through, video)
+ **Mindset:** Fake it; prototype only what you'll test. Aim for Goldilocks fidelity — sketches are too low for honest reactions, working code wastes time. It should look real without working for real (facades, click-throughs, video).
### Assign Roles
- **Makers** (2+ people):
- - Designer, writer, asset collector (images, icons)
- - Build the prototype
-
- **Stitcher** (1 person):
- - Combines pieces into final prototype
- - Usually in Keynote, Figma, or prototyping tool
-
- **Writer** (1 person):

- **Thursday afternoon:**
- - Stitch together
- - Review as team (does it match storyboard?)
- - Rehearse for Friday (run through entire flow)
- - Trial run (test with someone not on sprint team)
+ Morning: divide the storyboard into scenes and assign them to makers. Afternoon: stitch together, review against the storyboard, rehearse the full flow, and run a trial with someone outside the sprint team.
**Prototype checklist:**
- [ ] Follows storyboard exactly
- [ ] Looks real enough to get honest reactions
- [ ] Can walk through in 5-15 minutes

+ **Goal:** Interview 5 customers; learn what works and what doesn't.
### Setup
- **Interview room:**
- - Quiet space with table, 2 chairs
- - Laptop with prototype
- - Camera recording screen and customer face
-
- **Observation room:**

+ Interview room: quiet space, laptop with the prototype, camera recording screen and customer's face. Observation room: live video feed where the whole team watches and takes notes on a whiteboard. One **Interviewer** conducts all five interviews.
### The Five-Act Interview
- **Act 1: Friendly Welcome (5 min)**
- - Greet warmly
- - Explain you're testing prototype, not them
- - Ask permission to record
- - Encourage thinking aloud
-
- **Act 2: Context Questions (5 min)**
- - Ask about their background
- - Example: "Tell me about how you currently handle [problem]"
- - Goal: Understand their mindset and current behavior
-
- **Act 3: Introduce the Prototype (5 min)**
- - Show landing page or entry point
- - "What's this? What do you think it's for?"
- - Don't explain—let them interpret
- - Note: Do they get it?
-
- **Act 4: Tasks and Nudges (15 min)**
- - Give open-ended task: "Go ahead and explore"
- - Follow with specific tasks from storyboard: "Try to [complete action]"
- - Use nudges when stuck: "What would you do next?" or "What's going through your mind?"
- - Don't help—watch them struggle
- - Encourage thinking aloud
-
- **Act 5: Debrief (5 min)**
- - "What did you think overall?"
- - "Who is this for?"
- - "What worked? What was confusing?"
- - Ask about specific parts you're uncertain about
-
- **Interview length:** ~30 minutes per customer
+ About 30 minutes per customer, with 30-minute breaks between to discuss observations and adjust questions.
- **Between interviews:**
- - 30-minute break
- - Team discusses observations
- - Update questions if needed
+ | Act | Time | What to Do |
+ |-----|------|------------|
+ | **1. Friendly welcome** | 5 min | Greet warmly; explain you're testing the prototype, not them; get recording permission; encourage thinking aloud |
+ | **2. Context questions** | 5 min | "Tell me about how you currently handle [problem]" — understand mindset and current behavior |
+ | **3. Introduce prototype** | 5 min | "What's this? What do you think it's for?" Don't explain — let them interpret |
+ | **4. Tasks and nudges** | 15 min | Open-ended exploration, then storyboard tasks. When stuck: "What would you do next?", "What's going through your mind?" Don't help — watch them struggle |
+ | **5. Debrief** | 5 min | "What did you think overall?", "Who is this for?", "What worked? What was confusing?" |
### Five Is the Magic Number
- **Why 5 customers?**
- - Patterns emerge after 3-5 people
- - Diminishing returns after 5
- - Doable in one day (5 × 1 hour = 5 hours with breaks)
-
- **Who to recruit:**
- - Target customers (match your personas)
- - Screener survey to qualify
- - Incentive ($100-$200 for B2B, $50-$100 for B2C)
- - Schedule 6 (expect 1 no-show)
+ Patterns emerge after 3-5 people and returns diminish after 5 — and five 1-hour slots fit one day. Recruit target customers via a screener survey, offer an incentive ($100-$200 B2B, $50-$100 B2C), and schedule 6 to absorb a no-show.
### Take Notes: Pattern Recognition
- **While watching interviews, team captures:**
-
- | Column 1 | Column 2 | Column 3 | Column 4 | Column 5 |
- |----------|----------|----------|----------|----------|
- | Customer 1 notes | Customer 2 notes | Customer 3 notes | Customer 4 notes | Customer 5 notes |
+ Capture observations in a grid, one column per customer:
- **Mark with ✓, ✗, or ~:**
- - ✓ Positive reaction, success
- - ✗ Negative reaction, failure
- - ~ Neutral or mixed
+ | Customer 1 | Customer 2 | Customer 3 | Customer 4 | Customer 5 |
+ |------------|------------|------------|------------|------------|
+ | notes | notes | notes | notes | notes |
- **After all 5 interviews:**
- - Look for patterns (did all 5 struggle with the same thing?)
- - Count ✓ ✗ ~ per row
- - Identify what worked and what failed
+ Mark each observation **✓** (positive, success), **✗** (negative, failure), or **~** (neutral/mixed). After all five interviews, count marks per row and look for patterns — did all 5 struggle with the same thing?
### End-of-Sprint Debrief
- **Organize findings:**
-
- **✓ What worked:**
- - Features/flows that all customers understood
- - Messaging that resonated
- - Design that felt intuitive
-
- **✗ What failed:**
- - Confusing terminology
- - Missing steps
- - Wrong assumptions
-
- **~ Mixed results:**
- - Some got it, some didn't
- - Unclear if it matters
+ Organize findings: **✓ what worked** (flows everyone understood, messaging that resonated), **✗ what failed** (confusing terminology, missing steps, wrong assumptions), **~ mixed** (some got it, some didn't). Then decide next steps:
- **Next steps:**
- - **If core concept validated:** Build it (or next sprint on details)
- - **If major issues:** Pivot or next sprint to solve problems
- - **If totally failed:** Back to drawing board (but you saved months!)
+ - **Core concept validated:** build it, or run the next sprint on details
+ - **Major issues:** pivot, or sprint again on the problems
+ - **Total failure:** back to the drawing board — you just saved months
- **Friday output:**
- - Interview videos
- - Pattern notes
- - Clear list of what works, what doesn't
- - Decision on next steps
+ **Friday output:** interview recordings, pattern notes, a clear list of what works and what doesn't, decision on next steps.
See: [references/friday.md](references/friday.md) for interview scripts and note-taking templates.
## When to Run a Design Sprint
- **Run a sprint when:**
- - High-stakes decision
- - Not enough time to build and test normally
- - Team is stuck in endless debate
- - Multiple solutions possible
- - New product, feature, or major redesign
- - Need to de-risk before investing
+ **Run when:** the decision is high-stakes, there's no time to build and test normally, the team is stuck in endless debate, multiple solutions compete, it's a new product/feature/major redesign, or you need to de-risk before investing.
- **Don't run a sprint when:**
- - Problem is clear and solution is obvious
- - You just need to execute
- - Team isn't bought in
- - Can't get decision maker for full week
+ **Don't run when:** the problem and solution are obvious and you just need to execute, the team isn't bought in, or you can't get the Decider for the full week.
## Variations
- **4-Day Sprint:**
- - Day 1: Map + Sketch (compressed)
- - Day 2: Decide
- - Day 3: Prototype
- - Day 4: Test
-
- **Remote Sprint:**
- - Use Miro/FigJam for whiteboarding
- - Zoom for meetings
- - Same schedule, digital tools
-
- **Multi-Sprint:**
- - Sprint 1: Broad problem, choose direction
- - Sprint 2: Deep dive on chosen solution
- - Sprint 3: Refine details
+ - **4-Day Sprint:** Day 1 Map + Sketch (compressed), Day 2 Decide, Day 3 Prototype, Day 4 Test.
+ - **Remote Sprint:** Same schedule with Miro/FigJam whiteboards and Zoom.
+ - **Multi-Sprint:** Sprint 1 chooses direction on a broad problem, Sprint 2 deep-dives the chosen solution, Sprint 3 refines details.
## Common Mistakes
| Mistake | Why It Fails | Fix |
|---------|-------------|------|
| **Skip prototyping** | Nothing to test | Always prototype, even if simple |
| **Over-engineer prototype** | Waste time on details that don't matter | Facade only, not working code |
| **Test with wrong users** | Invalid feedback | Screen for target customers |
| **Explain prototype to users** | Defeats the test | Let them struggle, observe confusion |
| **No decision maker** | Can't commit to decision | Get Decider for full week or don't sprint |
| **Interruptions** | Breaks focus | Protect the week, no meetings/emails |
## Quick Diagnostic
Audit any sprint plan:
| Question | If No | Action |
|----------|-------|--------|
| Do we have a Decider for full week? | Sprint will fail | Get commitment or postpone |
| Is the problem important enough? | Waste of time | Only sprint on big challenges |
| Can we prototype in 1 day? | Wrong problem for sprint | Choose more concrete problem |
| Can we recruit 5 target users? | Can't test properly | Start recruiting now (2 weeks ahead) |
| Will team commit to no interruptions? | Won't maintain focus | Get buy-in from leadership |
