Methodology Foundation
| Aspect | Details |
|---|---|
| Source | Ryan Singer - Shape Up (2019), developed at Basecamp |
| Core Principle | "Fixed time, variable scope. Appetite, not estimates. Shape before you build." |
| Why This Matters | Traditional methods either micromanage (waterfall) or leave too much open (agile sprints without direction). Shape Up gives teams direction AND autonomy. |

- Enables cycles - 6-week focused work, 2-week cooldown
- Empowers teams - Autonomy within boundaries
- Provides betting tables - Principled prioritization
- Manages scope dynamically - Must-haves vs. nice-to-haves
How to Use
Shape a Feature Idea
I want to shape this feature idea: [description] Apply Shape Up methodology to define it at the right level. Appetite: [2 weeks / 6 weeks]
Plan a Cycle
We have these potential projects for the next cycle: [List of ideas] Help me run a betting table to decide what to build.
Manage Scope During Build
We're in week 3 of a 6-week cycle building [feature]. We're running behind. Help me apply Shape Up scope hammering.
Instructions
Step 1: Understand the Shape Up Principles
## The Shape Up Philosophy ### Fixed Time, Variable Scope **Traditional approach:** "How long will this take?" → Estimate → Build → Deadline slips **Shape Up approach:** "How much time is this worth?" → Appetite → Shape to fit → Ship on time **The mindset shift:** Instead of estimating how long a feature will take, decide how much time you're willing to spend. Then shape the work to fit that time. ### Appetite, Not Estimates **Appetite:** How much time is this problem WORTH solving? - Small batch: 2 weeks or less - Big batch: 6 weeks max **Key insight:** A feature can be built in 2 weeks OR 6 months. The question is: What version fits your appetite? **Example:** "Auto-complete for search" - 6-month version: ML-powered, personalized, learns preferences - 6-week version: Pre-populated common searches, basic matching - 2-week version: Static list of top searches All solve the problem. Choose based on appetite. ### Shaping vs. Building **Shaping (Senior people):** - Define the problem - Set boundaries - Identify risks - Rough solution direction - Leave room for builder creativity **Building (Teams):** - Detailed implementation - Technical decisions - UX specifics - Scope management within boundaries
Step 2: The Shaping Process
## How to Shape Work ### Step 1: Set the Appetite Before anything else, decide: - Is this a **small batch** (2 weeks) or **big batch** (6 weeks)? - Is this worth doing at all at this appetite? **Questions to ask:** - What problem are we solving? - How painful is this problem? - What's the opportunity cost of not doing it? - What's the opportunity cost of spending more time on it? ### Step 2: Narrow the Problem Don't shape "improve search." Shape "help new users find their first project template." **Narrowing technique:** 1. Start with the raw idea 2. Ask: Who specifically has this problem? 3. Ask: In what specific situation? 4. Ask: What's the minimum viable solution? ### Step 3: Rough Out the Solution **Fat marker sketches:** Draw the solution with a thick marker (no detail). You're defining spaces and flows, not buttons and fields. **Breadboarding:** For flows, use words not wireframes:
[Search box] → [Results page] → [Template detail] ↓ [No results] → [Suggest categories]
**Key principle:** Leave room for the builders to be creative. Define WHAT, not exactly HOW. ### Step 4: Identify Risks and Rabbit Holes **Rabbit holes:** Technical or design problems that could explode in scope. **For each potential rabbit hole:** - Name it - Decide: Solve it in shaping? Or declare it out of scope? - Document the boundary **Example:** "If we build template search, what about user-generated templates?" Decision: Out of scope. Only show official templates. ### Step 5: Write the Pitch **Pitch elements:** 1. **Problem:** What are we solving? 2. **Appetite:** How long is this worth? 3. **Solution:** Fat marker sketch / breadboard 4. **Rabbit holes:** What we're explicitly NOT doing 5. **No-gos:** Boundaries and constraints
Step 3: The Cycle
## Six-Week Cycles ### The Rhythm **6 weeks building:** - Long enough for meaningful work - Short enough to maintain urgency - Teams own their projects completely **2 weeks cooldown:** - Bug fixes - Technical debt - Exploration - Shaping for next cycle - Recovery ### Why 6 Weeks? **Shorter (2-week sprints):** - Not enough time for real progress - Constant planning overhead - Work gets chopped up artificially **Longer (quarters):** - Deadlines feel far away - Scope creeps - No urgency until the end **6 weeks:** - Urgent from day one - Room to figure things out - Clean endpoint ### Team Structure **Small teams:** - 1-2 designers + 1-3 programmers - Self-managed during the cycle - No daily standups with managers - Check-ins when THEY need help **Circuit breaker:** If work isn't done at 6 weeks, it doesn't automatically continue. It goes back to the betting table. Maybe it gets another cycle. Maybe it doesn't. ### What Teams Do in a Cycle **Week 1-2: Figure it out** - Understand the shaped work - Spike on unknowns - Get oriented - Early integration **Week 3-4: Build the core** - Make vertical slices - Connect the pieces - Working software early **Week 5-6: Polish and ship** - Cut scope if needed - Must-haves only - Ship by end of cycle
Step 4: The Betting Table
## Choosing What to Build ### The Betting Table **Who:** Senior people who can make commitments **When:** During cooldown, before next cycle **Input:** Shaped pitches **Output:** Cycle bets ### The Process **1. Review pitches** Each pitch should be complete: - Clear problem - Shaped solution - Identified risks - Appetite set **2. Consider each bet** For each pitch, ask: - Is this the right time? - Do we have the right team? - Are there dependencies? - What's the opportunity cost? **3. Make decisions** Options: - **Bet:** Assign to next cycle - **Park:** Good but not now - **Kill:** Not worth doing **No backlog:** If you don't bet on something, it goes away. Good ideas come back. Bad ideas don't. ### Betting Criteria **1. Strategic fit** Does this support current company goals? **2. Problem significance** How painful is this for customers? **3. Appetite match** Can this actually be done in the proposed time? **4. Team availability** Who would work on this? **5. Dependencies** What else needs to be true? ### Anti-Patterns **Carry-over:** "We didn't finish last cycle, so we'll continue." No. Circuit breaker. Re-evaluate. Maybe it's not worth it. **Backlog grooming:** "Let's go through the 200 ideas and prioritize." No. Only consider shaped pitches. Unshaped ideas aren't real options. **Consensus:** "Let's vote on what to build." No. Decision-makers decide. Not democracy.
Step 5: Managing Scope
## Scope Hammering ### The Principle Scope grows naturally. Left unchecked, projects expand to fill time. Your job is to constantly hammer scope back to what matters. ### Must-Haves vs. Nice-to-Haves **Must-haves:** - Core value delivery - Without this, the feature doesn't work - Absolutely required for ship **Nice-to-haves:** - Polish - Edge cases - Delighters - "While we're at it..." **Rule:** Identify nice-to-haves early. Cut them first. ### The Scope Hammer **When you're behind (week 3+):** 1. **List all remaining work** 2. **Classify each item:** - Must-have for THIS version - Nice-to-have (cut or defer) 3. **Cut aggressively:** - What's the smallest version that still delivers value? - What can be a follow-up? - What can we not do at all? ### Scope Hammering Questions - "Is this necessary for launch, or is it polish?" - "What's the simplest version that still solves the problem?" - "Can this be a fast-follow?" - "What would happen if we just... didn't do this?" - "Are we building for the 80% case or the edge case?" ### Hill Charts **Track progress visually:**
┌─────────────────────────────────┐ │ ↗ Feature C │ │ ↗ Feature B │ │ ↗ Feature A ↘ Feature D └─────────────────────────────────┘ Figuring it out Making it happen
- **Uphill:** Still figuring it out (risky) - **Downhill:** Know what to do, just executing (safe) **Use for:** - Early warning when something is stuck uphill - Identifying where help is needed - Manager visibility without micromanagement
Examples
Example 1: Shaping a Feature
Input:
"We want to add notifications to our project management app. Can you help me shape this using Shape Up?"
Output:
Shaped Pitch: Project Notifications
Problem
Users miss important updates because they only check the app occasionally. When they do check, they see a firehose of activity with no way to know what actually matters.
Specific situation: A project manager logs in after a day away and can't quickly tell what needs their attention.
Appetite
6 weeks (Big Batch)
Notifications are foundational. Worth investing in properly. But not worth 3 months. We'll scope to fit 6 weeks.
Solution
Breadboard:
[Activity happens] → [Notification created] → [Notification center] ↓ [Settings: what to notify]
Fat marker sketch:
┌─────────────────────────────────────┐ │ 🔔 (3) │ ← Bell in header with count ├─────────────────────────────────────┤ │ ┌─────────────────────────────────┐ │ │ │ ● @you in Project Alpha │ │ ← Unread notifications │ │ Sarah mentioned you in a... │ │ │ │ 2 hours ago │ │ │ ├─────────────────────────────────┤ │ │ │ ○ Task completed │ │ ← Read notifications │ │ Build specs was marked done │ │ │ │ Yesterday │ │ │ └─────────────────────────────────┘ │ └─────────────────────────────────────┘
What we're building:
- In-app notification center (bell icon, dropdown)
- Notifications for: @mentions, task assignments, due dates
- Basic settings (on/off per type)
Rabbit Holes (Explicitly OUT of Scope)
Email notifications: This is a whole separate system (deliverability, unsubscribes, formatting). Out of scope. Potential future small batch.
Mobile push notifications: Requires native app work. Out of scope.
Notification grouping: "5 comments on Project Alpha" instead of 5 separate notifications. Nice-to-have. Cut if we need time.
Real-time updates: WebSockets for instant notifications. Nice-to-have. Polling every 60 seconds is fine for V1.
Customization per project: "Only notify me for Project X." Too complex. Start with global settings only.
No-Gos
- No email notifications
- No mobile push
- No notification sounds
- No digest/summary views
- No team-level settings
Risks
Risk 1: Database load Many notifications could be created. Need efficient queries. Mitigation: Tech lead should spike on notification storage approach in first 2 days of cycle.
Risk 2: UX complexity Settings can get complicated fast. Mitigation: Start with just 3 toggles. No per-project settings.
Example 2: Scope Hammering Mid-Cycle
Input:
"We're in week 4 of a 6-week cycle building a reporting dashboard. We're behind. We have: (1) 5 chart types planned, only 2 done, (2) Export to PDF not started, (3) Date filters mostly done, (4) Real-time refresh not started. Help me scope hammer."
Output:
Scope Hammer: Reporting Dashboard
Current Status (Week 4 of 6)
| Item | Status | Time Needed |
|---|---|---|
| Chart types (5 planned) | 2 done | 1.5 weeks for remaining 3 |
| Export to PDF | Not started | 1 week |
| Date filters | 80% done | 2 days |
| Real-time refresh | Not started | 1 week |
Total remaining work: ~4 weeks Time available: ~2 weeks
Classification
Must-Have (Core value delivery):
- At least 3 chart types (line, bar, pie) - most common use cases
- Date filters - useless without filtering
- View/load reports - basic functionality
Nice-to-Have (Cut or defer):
- 4th and 5th chart types (table, area)
- Export to PDF
- Real-time refresh
Recommendation
Cut now:
- Real-time refresh → V2. Manual refresh button is fine.
- 5th chart type (area) → V2. Rarely used.
- Export to PDF → V2. Users can screenshot or we do fast-follow.
Keep:
- Date filters (finish in 2 days)
- 3 chart types (line, bar, pie - 3-4 days for remaining 1)
- 4th chart type (table) - useful for data review (3 days)
Revised Scope
Week 5:
- Day 1-2: Finish date filters
- Day 3-4: Build pie chart (3rd type)
- Day 5: Build table view (4th type)
Week 6:
- Day 1-3: Polish, bug fixes, edge cases
- Day 4: Internal testing
- Day 5: Ship
What to Tell Stakeholders
"We're shipping a fully functional dashboard with 4 chart types (line, bar, pie, table) and date filters. Export and real-time refresh will be fast-follows in the next small batch cycle.
This gives users 90% of the value. The remaining features are polish, not core functionality."
Post-Cycle Small Batch Candidates
- Export to PDF (2-week batch)
- Real-time refresh (2-week batch)
- Area chart type (1-week add-on)
Example 3: Running a Betting Table
Input:
"We have these 5 pitches for the next cycle. How do I run a betting table to decide? (1) Improved search, (2) Team permissions, (3) Mobile app redesign, (4) API for integrations, (5) Onboarding improvements"
Output:
Betting Table: Next Cycle
Pre-Work: Pitch Review
Each pitch should be shaped with:
- Clear problem statement
- Appetite (2-week or 6-week)
- Rough solution
- Rabbit holes identified
- No-gos defined
Assessment:
| Pitch | Shaped? | Appetite | Team Needed |
|---|---|---|---|
| Improved search | ✓ Yes | 6 weeks | 1D + 2E |
| Team permissions | ✓ Yes | 6 weeks | 1D + 2E |
| Mobile app redesign | ✗ Too vague | ? | ? |
| API for integrations | ✓ Yes | 6 weeks | 0D + 3E |
| Onboarding improvements | ✓ Yes | 2 weeks | 1D + 1E |
Mobile app redesign: Not ready for betting. Needs shaping. Send back. Consider for future cycle.

The Bet
Available capacity:
- 2 teams for 6-week bets
- 1 team has room for 2-week addition
Decision:
| Bet | Team | Rationale |
|---|---|---|
| Team Permissions | Team B | Enterprise blocker, highest urgency |
| API for Integrations | Team C | Opens strategic opportunities |
| Onboarding Improvements | Team A (week 1-2) | High impact, small investment |
| Improved Search | Parked | Good but not highest priority now |
What's NOT bet:
- Mobile app redesign: Not shaped. Needs work.
- Improved search: Good pitch, wrong timing. Save for next cycle.
Post-Betting Communication
"Next cycle:
- Team B: Team Permissions (6 weeks)
- Team C: API v1 (6 weeks)
- Team A: Onboarding improvements (2 weeks), then cooldown tasks
Search is a strong pitch. We're parking it for the following cycle. Mobile app redesign needs more shaping before it's ready to bet."
