## Executive Summary

Running Lean by Ash Maurya (1st ed. 2012, 3rd ed. 2022, O'Reilly) provides a systematic, evidence-driven methodology for iterating from an initial business idea (Plan A) to a validated business model that works. The book integrates concepts from the Lean Startup, Business Model Canvas, Design Thinking, and Jobs-to-be-Done into a unified framework centered on the Lean Canvas, a one-page business model tool.

The core methodology follows three meta-stages: **Document** (capture your Plan A on a Lean Canvas), **Validate** (systematically test riskiest assumptions through staged experiments), and **Scale** (optimize and grow a validated model). Within validation, Maurya defines a precise progression: Customer-Problem Fit, Problem-Solution Fit, Product-Market Fit, and Scale. The 3rd edition introduces the **Continuous Innovation Framework** and the **GO-LEAN** cycle for structured 90-day validation sprints.

For an AI product owner agent, Running Lean provides directly actionable artifacts: the Lean Canvas as a structured hypothesis document, the Traction Roadmap as an outcome-oriented milestone tracker, the Customer Factory model as a metrics framework, and the Mafia Offer as a validation technique -- all of which can be mapped to user story generation, prioritization, and acceptance criteria derivation.

## 1. Core Methodology

### 1.1 The Lean Canvas

**Evidence**: The Lean Canvas is "a 1-page business modeling tool that helps you deconstruct an idea into key assumptions or beliefs." Maurya derived it from Alexander Osterwalder's Business Model Canvas with a self-imposed design constraint: "every time he added a new box (like Problem), he'd remove an old box (like Key Partners)."

**Sources**: [LEANFoundry -- What is Lean Canvas](https://www.leanfoundry.com/articles/what-is-lean-canvas), [Business Model Toolbox -- Lean Canvas](https://bmtoolbox.net/tools/lean-canvas/), [O'Reilly -- Running Lean 3rd Edition](https://www.oreilly.com/library/view/running-lean-3rd/9781098108762/)

**Confidence**: High

#### The Nine Boxes

| Box | Definition | BMC Replacement |
|-----|-----------|-----------------|
| **1. Customer Segments** | Who pays for the product? Distinguish customers from users. Target early adopters specifically. | Retained from BMC |
| **2. Problem** | Top 1-3 most pressing customer problems. Document existing alternatives. | Replaces Key Partners |
| **3. Unique Value Proposition (UVP)** | "Why is your product different and worth paying attention to?" Focus on desired outcomes, not features. | Retained from BMC |
| **4. Solution** | Minimal sketch of the simplest approach to address each problem. Intentionally kept sparse. | Replaces Key Activities |
| **5. Channels** | How you reach customers initially and which scalable channels you build over time. | Retained from BMC |
| **6. Revenue Streams** | Pricing model and revenue sources. "Price is part of the product" -- pricing early validates willingness to pay. | Retained from BMC |
| **7. Cost Structure** | Expenses for MVP development and 3-6 months of operations. | Retained from BMC |
| **8. Key Metrics** | 3-5 outcome metrics (customer-centric). Leading indicators over trailing. | Replaces Key Resources |
| **9. Unfair Advantage** | What cannot be easily copied: insider info, network effects, existing customers. Leave blank if uncertain. | Replaces Customer Relationships |

**Recommended Fill Order**: Customer Segments -> Problem -> UVP -> Solution -> Channels -> Revenue Streams -> Cost Structure -> Key Metrics -> Unfair Advantage (hardest, often last).

**Practical Guidance**: Set a 20-minute timer for initial canvas. Avoid groupthink by having team members create individual canvases first. Leave boxes blank rather than forcing answers. Write in present tense focused on immediate next hypotheses.

**Confidence**: High

### 1.2 The Three Meta-Steps: Document, Validate, Scale

**Evidence**: The Running Lean process is structured as three sequential phases that take your original business plan (Plan A) and systematically iterate toward a plan that works.

#### Step 1: Document Your Plan A
Capture your initial business hypothesis on the Lean Canvas. This is explicitly a hypothesis document, not a business plan. Every box contains an assumption to be tested.

#### Step 2: Identify and Validate the Riskiest Parts of Your Plan
Systematically prioritize and test assumptions by their risk level. Risks are categorized into three types:
- **Customer Risk** (C): Are these the right customers?
- **Problem Risk** (P): Is this a real, significant problem worth solving?
- **Market Risk** (M): Is there sufficient market demand?

#### Step 3: Scale What Works
Once a repeatable business model is validated, optimize and grow.

**Confidence**: High

### 1.3 The 3rd Edition: Continuous Innovation Framework (2022)

The 3rd edition (367 pages, O'Reilly, March 2022) introduces the **Continuous Innovation Framework** and integrates concepts from Design Thinking and Jobs-to-be-Done. Key additions include:

- **Stress-testing for three dimensions**: Desirability (do customers want it?), Viability (can it be a business?), Feasibility (can we build it?)
- **Traction Roadmap**: Outcome-oriented milestones replacing traditional product roadmaps
- **GO-LEAN cycle**: Goal, Obstacle, Learn, Experiment, Analyze, Next Action
- **Customer Forces Canvas**: Maps triggering events, existing alternatives, and switching moments (integrating JTBD thinking)
- **90-Day Validation Cycles**: Structured quarterly sprints for assumption testing

**Confidence**: High

## 2. The Validation Progression: From Idea to Scale

### 2.1 Stage 1: Business Model Design (Founder-Model Fit)

**Evidence**: The initial phase involves deconstructing your vision into key business model assumptions using Lean Canvas. Founders identify and stress-test their riskiest assumptions to refine or eliminate weaker models, aiming for "2-3 strong business models that have the greatest chance of success."

**Milestone**: Founder-business/model fit -- you have identified a business model worth pursuing.

**Sources**: [LEANFoundry -- Systematic Roadmap](https://www.leanfoundry.com/articles/a-systematic-roadmap-to-product-market-fit), [O'Reilly -- Running Lean 3rd Edition](https://www.oreilly.com/library/view/running-lean-3rd/9781098108762/)

**Confidence**: High

### 2.2 Stage 2: Customer-Problem Fit (~4 weeks)

**Evidence**: Conducted through "carefully scripted problem discovery interviews" rather than surveys. The goal is to demonstrate evidence of "a sufficiently large problem worth solving." Maurya's Problem Interview has three discovery goals: (1) what problems are being solved and how customers rank their top 3 problems, (2) who is the competition and how customers solve these problems today, and (3) who has the pain and whether this is a viable customer segment.

The 3rd edition updates the Problem Interview with the **Customer Forces Canvas**, incorporating JTBD thinking: "a better framing is around triggers and desired outcomes. Triggers create a desire for better. Taken together, the trigger and desired outcome create anchor points for the customer journey story you want to learn about."

**Milestone**: Validated that a problem exists, matters to customers, and is worth solving.

**Sources**: [LEANFoundry -- Systematic Roadmap](https://www.leanfoundry.com/articles/a-systematic-roadmap-to-product-market-fit), [Product Masterclass -- Interview with Ash Maurya](https://www.product-masterclass.com/blog/interview-with-ash-maurya-lean-canvas-creator-and-author-of-running-lean-and-scaling-lean), [StartitUp -- Problem Interview Script](http://startitup.co/guides/285/problem-interview-script)

**Confidence**: High

### 2.3 Stage 3: Problem-Solution Fit (~6 weeks)

**Evidence**: Tests demand without building a full product using the **DEMO-SELL-BUILD approach** (reversing the traditional Build-Demo-Sell). This stage uses the **Mafia Offer** -- an irresistible offer combining UVP, demonstration, and call-to-action, targeting 80-90% conversion.

The Mafia Offer process:
1. **Customer Discovery**: Interview enough customers to understand their problems better than they do
2. **Solution Design**: Use interview insights to design the right solution and assemble an offer (UVP + Demo + Price)
3. **Face-to-Face Validation**: Sell the offer to 10 customers face-to-face. Get feedback if they refuse. Fix the offer until it can be repeatedly sold.

**Milestone**: Demonstrated demand before building the product. Evidence of willingness to pay.

**Sources**: [LEANFoundry -- Sell Before You Build](https://www.leanfoundry.com/lean-1-2-3/feb-24-2024), [LEANFoundry -- Systematic Roadmap](https://www.leanfoundry.com/articles/a-systematic-roadmap-to-product-market-fit), [SlideShare -- The Mafia Offer](https://www.slideshare.net/VladimirBlagojevic/the-mafia-offer-how-to-presell-your-product-at-80-conversion-rate)

**Confidence**: High

### 2.4 Stage 4: Solution-Customer Fit (~6 months)

**Evidence**: Develops MVP and pilots with early-access customers. Secures referenceable testimonials from initial users. Applies stage-based thinking to prioritize assumptions without overwhelm.

**Milestone**: Referenceable early customers who testify the solution delivers on its promise.

**Sources**: [LEANFoundry -- Systematic Roadmap](https://www.leanfoundry.com/articles/a-systematic-roadmap-to-product-market-fit), [O'Reilly -- Running Lean 3rd Edition](https://www.oreilly.com/library/view/running-lean-3rd/9781098108762/)

**Confidence**: Medium -- fewer independent sources on this specific sub-stage

### 2.5 Stage 5: Product-Market Fit and Scale

**Evidence**: "Product/market fit takes roughly two years to achieve, and 80% of products never get there." It is achieved when you have "sufficient traction to derisk your value hypotheses." Focus shifts to understanding unit economics, optimizing for profitability, and identifying growth channels.

Maurya defines traction as "the rate at which a business model creates monetizable value" -- not vanity metrics like signups or raw revenue. Progress is measured in 90-day cycles, balancing accountability with sufficient time for meaningful results.

**Milestone**: Repeatable, scalable business model with demonstrated traction.

**Confidence**: High

## 3. Metrics and KPIs

### 3.1 Actionable Metrics vs. Vanity Metrics

**Evidence**: An actionable metric "ties specific and repeatable actions to observed results." Vanity metrics (web hits, total downloads, total registered users) "only document the product's current state but offer no insight into how we got here or what to do next."

| Dimension | Vanity Metrics | Actionable Metrics |
|-----------|---------------|-------------------|
| **What they measure** | Business size (total users, total revenue, leads) | Individual behavior (conversion rates, activation rates, churn) |
| **Data type** | Gross quantities and aggregates | Ratios and unit economics |
| **Cause & effect** | Don't indicate product-market fit; can be inflated through spending | Directly signal product-market fit through behavioral improvements |
| **Examples** | Website visitors, social media followers, total registered users, total revenue | Conversion rate, repeat rate, churn rate, CAC, CLTV |
| **When useful** | Scaling stage (demonstrating growth trajectory to external audiences) | Early-stage validation (testing business model hypotheses) |

**Sources**: [Effective Software Design -- Vanity Metrics and Actionable Metrics](https://effectivesoftwaredesign.com/2021/03/23/lean-startup-principles-vanity-metrics-and-actionable-metrics/), [LeanStack Blog -- 3 Rules to Actionable Metrics](https://blog.leanstack.com/3-rules-to-actionable-metrics-in-a-lean-startup/), [FasterCapital -- Lean Startup vs Running Lean](https://fastercapital.com/content/Lean-Startup-vs-Running-Lean--How-to-Use-the-Lean-Startup-Methodology-and-the-Running-Lean-Book-as-a-Guide.html)

**Confidence**: High

### 3.2 The Customer Factory Model (Pirate Metrics / AARRR)

**Evidence**: The Customer Factory Blueprint models your business as a "production line for creating happy customers," mapping the customer lifecycle into five stages inspired by Dave McClure's Pirate Metrics (AARRR):

| Stage | Description | Key Question |
|-------|-------------|-------------|
| **Acquisition** | How do users discover you? | Are we reaching the right people? |
| **Activation** | Do users have a great first experience? | Are users getting to the "aha moment"? |
| **Retention** | Do users come back? | Are users deriving ongoing value? |
| **Revenue** | Do users pay? | Is the business model sustainable? |
| **Referral** | Do users tell others? | Is growth organic? |

**Critical Insight**: Maurya identifies **Activation** as the most important step because it is "causal" -- it has the most lines leading out of it. Making customers happy at activation *causes* them to buy (Revenue), keep coming back (Retention), and refer others (Referral).

The Customer Factory combines Pirate Metrics with **Theory of Constraints** (from Goldratt's *The Goal*): identify bottlenecks in the production system, then optimize work at the constraint. "In any system, only a single bottleneck or constraint (weakest link) is always holding back throughput."

**Confidence**: High

### 3.3 The One Metric That Matters (OMTM)

**Evidence**: OMTM is "the only metric you care about above anything else at any given time." The concept was formalized in *Lean Analytics* by Ben Yoskovitz and Alistair Croll, and Maurya has integrated and endorsed it within his framework.

**Four reasons to use OMTM**:
1. **Focus**: Prevents chasing multiple metrics simultaneously
2. **Communication**: Concentrates team, investor, and media messaging
3. **Sequential progression**: Optimizing one metric reveals the next critical one (the "squeeze toy" principle)
4. **Behavioral change**: Forces agreement on what change means before collecting data

**Good metric characteristics**:
- Rates or ratios rather than absolute numbers
- Comparable across time periods or segments
- Simple enough to remember
- Predictive for planning
- Behavior-changing for experimentation

**Stage-based OMTM selection** (from Lean Analytics, aligned with Maurya's Customer Factory):

| Stage | Focus | Example OMTM |
|-------|-------|--------------|
| Empathy | Problem validation | Qualitative pain intensity from interviews |
| Stickiness | Retention and engagement | Churn rate, DAU/MAU ratio |
| Virality | Organic growth | Viral coefficient, referral rate |
| Revenue | Monetization | Customer Lifetime Value, MRR |
| Scale | Growth efficiency | CAC/LTV ratio, payback period |

**Sources**: [Lean Analytics Book -- One Metric That Matters](https://leananalyticsbook.com/one-metric-that-matters/), [Product Masterclass -- Interview with Ash Maurya](https://www.product-masterclass.com/blog/interview-with-ash-maurya-lean-canvas-creator-and-author-of-running-lean-and-scaling-lean), [LEANFoundry -- The One Metric](https://www.leanfoundry.com/lean-1-2-3/may-1-2025), [UserPilot -- What is OMTM](https://userpilot.com/blog/one-metric-matters-omtm/)

**Confidence**: High

### 3.4 The Traction Model

**Evidence**: Maurya defines traction as "the rate at which a business model creates monetizable value." The Traction Model is to the financial model what the Lean Canvas is to the business plan -- a concise, metrics-driven representation.

The **Traction Roadmap** "replaces fictional financial forecasts with an actionable roadmap built on just 7 key metrics." It charts "key business model outcomes as milestones on a timeline" and creates "a contract with key stakeholders on outcome deliverables (what you will achieve) while suspending output deliverables (how you will achieve it) for later."

The Traction Roadmap uses a **Now, Next, Later** stage-based approach for milestone planning.

**Confidence**: High

## 4. Experiment Design: The GO-LEAN Cycle

### 4.1 The GO-LEAN Framework

**Evidence**: The 3rd edition introduces GO-LEAN as the systematic approach to identifying and tackling riskiest assumptions within 90-day cycles.

| Step | Action | Purpose |
|------|--------|---------|
| **G** - Goal | Define a specific 90-day goal from the Traction Roadmap | Establish clear direction |
| **O** - Obstacle | Use Customer Factory + Theory of Constraints to identify the single bottleneck | Find the weakest link |
| **L** - Learn | Surface root causes through discovery (not guessing). Foster diverse solutions, require evidence. | Prevent premature optimization |
| **E** - Experiment | Run small, fast, additive experiments. Each isolates one variable. Time-boxed. | Test riskiest assumption first |
| **A** - Analyze | Detect shifting constraints. Review Customer Factory throughput weekly. | Identify when bottleneck moves |
| **N** - Next Action | Focus ruthlessly on the few actions that drive meaningful impact. | Maintain momentum |

**Key principle**: "Incorrect prioritization of risk is one of the top contributors to waste in a startup." Maurya recommends dedicating 80% of effort to solving the single biggest bottleneck.

**Sources**: [LEANFoundry -- GO-LEAN](https://www.leanfoundry.com/articles/how-to-systematically-prioritize-and-tackle-the-riskiest-assumptions-in-your-business-model), [LEANFoundry -- The One Metric](https://www.leanfoundry.com/lean-1-2-3/may-1-2025), [O'Reilly -- Running Lean 3rd Edition Ch. 6](https://www.oreilly.com/library/view/running-lean-3rd/9781098108762/ch06.html)

**Confidence**: High

### 4.2 The 90-Day Validation Cycle

**Evidence**: Running Lean structures validation into quarterly cycles:
- **Month 1**: Define goal -> Identify constraint -> Surface learning insights
- **Month 2**: Design and run experiments -> Iterate based on signals
- **Month 3**: Analyze results -> Detect new constraints -> Plan next actions

90 days are favored because they are "typically long enough" for meaningful results while maintaining accountability.

### 4.3 Assumption Prioritization

**Evidence**: Use a 2x2 matrix with "likelihood of stopping the project" (Y-axis) and "amount of evidence available" (X-axis). Prioritize assumptions that are: (a) most likely to kill the project and (b) have the least evidence. This quadrant represents the riskiest assumptions to test first.

Three risk categories from the Lean Canvas:
- **Customer Risk**: Customer Segments box
- **Problem Risk**: Problem, Existing Alternatives boxes
- **Market Risk**: Revenue Streams, Cost Structure, Unfair Advantage boxes

**Sources**: [LEANFoundry -- GO-LEAN](https://www.leanfoundry.com/articles/how-to-systematically-prioritize-and-tackle-the-riskiest-assumptions-in-your-business-model), [LEANFoundry -- Systematic Roadmap](https://www.leanfoundry.com/articles/a-systematic-roadmap-to-product-market-fit), [Grokipedia -- Running Lean](https://grokipedia.com/page/running_lean_iterate_from_plan_a_to_a_plan_that_works_(book))

**Confidence**: High

### 4.4 Experiment Types by Stage

| Validation Stage | Experiment Type | Method | Evidence Produced |
|-----------------|----------------|--------|-------------------|
| Customer-Problem Fit | Problem Interview | Scripted discovery conversations | Ranked problem list, existing alternatives, customer segment validation |
| Problem-Solution Fit | Mafia Offer | UVP + Demo + Price, sold face-to-face | Conversion rate (target: 80-90%), willingness to pay |
| Solution-Customer Fit | MVP Pilot | Early-access product with real customers | Referenceable testimonials, activation metrics |
| Product-Market Fit | Growth Experiments | Channel testing, pricing optimization | Unit economics, repeatability evidence |

---

## 5. Practical Artifacts and Outputs

### 5.1 Artifact Inventory

Running Lean produces the following concrete artifacts that could be integrated into a requirements gathering process:

| Artifact | Description | When Created | Value for Requirements |
|----------|-------------|-------------|----------------------|
| **Lean Canvas** | One-page business model hypothesis | Phase 1 (Document) | Defines scope, constraints, customer segments, problems, and success metrics |
| **Problem Interview Script** | Structured conversation guide for customer discovery | Phase 2 (Validate -- Customer-Problem Fit) | Surfaces real problems, existing alternatives, and customer language |
| **Customer Forces Canvas** | Maps triggers, desired outcomes, existing alternatives, switching forces | Phase 2 (Validate) | Provides JTBD-aligned context for user stories |
| **Mafia Offer** | UVP + Demo + Pricing package | Phase 2 (Validate -- Problem-Solution Fit) | Validates willingness to pay and core value proposition |
| **Traction Roadmap** | Outcome-oriented milestone timeline with 7 key metrics | Phase 2-3 | Replaces speculative roadmaps with evidence-based milestones |
| **Customer Factory Dashboard** | Weekly AARRR metrics tracker | Phase 2-3 | Identifies bottlenecks and constraint-based priorities |
| **90-Day Cycle Plan** | Quarterly validation strategy with specific goals and experiments | Phase 2-3 | Structures iteration cadence |
| **Experiment Reports** | Results of each validation experiment (what was tested, evidence gathered, decision made) | Throughout | Audit trail of validated/invalidated assumptions |

### 5.2 Artifacts Directly Usable by an AI Product Owner

For an AI product owner agent generating requirements documents, the most directly applicable artifacts are:

1. **Lean Canvas as Requirements Context**: Each box maps to a category of requirements constraint. The Problem box defines the "why," Customer Segments defines the "who," Solution defines the "what" (at minimum), Key Metrics defines the "how we measure success."

2. **Problem Interview Findings as User Story Source**: Customer-reported problems, existing alternatives, and desired outcomes (from the Customer Forces Canvas) are direct inputs for user stories of the form: "As a [customer segment], I want to [desired outcome], so that [trigger/problem is resolved]."

3. **Traction Roadmap as Prioritization Framework**: Milestones from the traction roadmap define what must be true at each stage, directly informing which user stories to prioritize in which sprint.

4. **Customer Factory Metrics as Acceptance Criteria**: Each AARRR stage provides measurable criteria. For example, an Activation-stage user story might have acceptance criteria: "Given a new user completes onboarding, when they perform the core action, then the activation rate increases by X%."

---

## 6. Connecting KPIs to User Stories: A Practical Integration Model

### 6.1 The Mapping Chain

**Interpretation** [labeled as analysis, not sourced fact]: Based on the Running Lean methodology, a structured chain connects business model validation to user story prioritization:

```
Lean Canvas Box          ->  Business Model Assumption
                         ->  Riskiest Assumption (prioritized)
                         ->  Customer Factory Stage (AARRR)
                         ->  OMTM for current stage
                         ->  Measurable Outcome (acceptance criterion)
                         ->  User Story (with KPI-linked "so that")
                         ->  Sprint Priority (based on constraint)
```

### 6.2 Deriving Measurable Outcomes from the Lean Canvas

| Lean Canvas Box | Assumption Type | Derived KPI | User Story Pattern |
|----------------|-----------------|-------------|-------------------|
| **Problem** | Problem Risk | % of interviews confirming problem severity >= 4/5 | "As a [segment], I struggle with [problem], so that [desired outcome]" |
| **Customer Segments** | Customer Risk | Segment size, reachability, willingness to pay | "As a [specific early adopter], I need..." |
| **UVP** | Problem Risk | Unique click-through rate, message-market fit | "The system communicates [UVP] so that [conversion target]" |
| **Solution** | Problem Risk | Activation rate, task completion rate | "As a [segment], I can [solution action], so that [problem resolved]" |
| **Channels** | Market Risk | CAC by channel, channel conversion rate | Operational stories about reach and distribution |
| **Revenue Streams** | Market Risk | ARPU, LTV, pricing conversion | "As a [segment], I can purchase [offer], so that [revenue target]" |
| **Key Metrics** | All | The OMTM for the current stage | Meta-story: "We track [metric] to validate [assumption]" |
| **Unfair Advantage** | Market Risk | Defensibility score, competitive moat indicators | Long-term strategic stories |
| **Cost Structure** | Market Risk | Burn rate, unit economics | Constraint on implementation choices |

### 6.3 Constraint-Based Prioritization

**Interpretation** [labeled as analysis]: The Customer Factory + Theory of Constraints approach provides a rigorous prioritization model:

1. **Map the current Customer Factory state**: What are the weekly numbers for each AARRR stage?
2. **Identify the constraint**: Which stage has the worst conversion/throughput?
3. **Derive the OMTM**: The metric that measures the constraint becomes the OMTM
4. **Prioritize stories that address the constraint**: All stories in the current sprint should target improving the OMTM
5. **Set acceptance criteria with measurable thresholds**: "This story is done when [OMTM] improves from X to Y"
6. **Re-evaluate weekly**: Constraints shift when solved; the next bottleneck becomes the new priority

This approach ensures that user story prioritization is evidence-driven rather than opinion-driven, directly addressing Maurya's concern that "incorrect prioritization of risk is one of the top contributors to waste."

### 6.4 Practical Example

**Scenario**: A SaaS product has validated Customer-Problem Fit (problems confirmed via interviews) and is working on Problem-Solution Fit.

**Current Customer Factory state**:
- Acquisition: 100 visitors/week
- Activation: 15 sign up (15%)
- Retention: 3 return after week 1 (20%)
- Revenue: 1 converts to paid (33% of retained)
- Referral: 0

**Constraint identified**: Retention (20% is the bottleneck)

**OMTM**: Week-1 retention rate

**User stories prioritized for this sprint**:
1. "As a new user who signed up, I want to receive a guided onboarding sequence, so that I understand how to get value from the product within my first session" -- AC: Week-1 retention improves from 20% to 35%
2. "As a returning user, I want to see my progress from last session, so that I feel momentum and reason to continue" -- AC: Day-3 return rate improves from 10% to 25%

**Stories deferred** (not the current constraint):
- Referral features (no point driving referrals if users do not retain)
- Advanced pricing tiers (revenue conversion is actually good at 33% of retained)

## 7. Integration Recommendations for AI Product Owner Agent

### 7.1 Lean Canvas as Structured Input

The AI product owner agent should accept a Lean Canvas (structured as nine fields) as a primary input for requirements generation. Each field provides context that constrains and informs the user stories produced.

**Recommended input schema**:
```
lean_canvas:
  customer_segments: [string]      # Who are the target users/customers?
  early_adopters: [string]         # Who are the first customers?
  problems: [string]               # Top 1-3 problems
  existing_alternatives: [string]  # How do they solve it today?
  uvp: string                      # Why different and worth attention?
  solution: [string]               # Minimum solution elements
  channels: [string]               # How to reach customers
  revenue_streams: [string]        # How money is made
  cost_structure: [string]         # Key costs
  key_metrics: [string]            # 3-5 outcome metrics
  unfair_advantage: string         # Defensibility (optional)
```

### 7.2 Stage-Aware Story Generation

The agent should understand the current validation stage and generate stories appropriate to that stage:

| Validation Stage | Story Focus | Story Type |
|-----------------|-------------|------------|
| Customer-Problem Fit | Discovery and research | Interview scripts, survey designs, problem validation experiments |
| Problem-Solution Fit | Demand validation | Landing pages, demo flows, offer pages, pre-sell experiments |

### 7.3 Metrics-Linked Acceptance Criteria

Every user story should include acceptance criteria linked to the OMTM or a supporting metric from the Customer Factory model. The agent should prompt for:
- Current metric baseline
- Target metric threshold
- Measurement method
- Time horizon for measurement

### 7.4 Cross-Reference with JTBD

Running Lean's Customer Forces Canvas aligns directly with the Jobs-to-be-Done framework (see existing research: `/mnt/c/Repositories/Projects/nWave-dev/docs/research/jtbd-framework-comprehensive-research.md`). The AI product owner should use:
- **Triggers** (from Customer Forces Canvas) as user story context
- **Desired outcomes** (from JTBD) as the "so that" clause
- **Existing alternatives** as competitive context informing UVP-based stories

**Note on Source Concentration**: Seven sources are from leanfoundry.com/leanstack.com (Ash Maurya's own platforms). While these are the most authoritative sources for his methodology, they represent author-sourced content, not independent verification. All major claims from these sources have been cross-verified against at least one independent source.

## Knowledge Gaps

### Gap 1: Detailed 90-Day Cycle Templates
**Issue**: The exact structure of experiment report templates and weekly tracking sheets used within 90-day cycles is not publicly documented in detail -- this is part of Maurya's paid LEANSTACK tooling.
**Attempted**: Searched leanfoundry.com, leanstack.com, O'Reilly chapter previews.
**Recommendation**: Purchase the Running Lean 3rd edition or access via O'Reilly subscription for complete templates. Alternatively, LEANSTACK's SaaS platform provides digital versions.

### Gap 2: Quantitative Benchmarks by Industry
**Issue**: Running Lean does not provide industry-specific metric benchmarks (e.g., "good" activation rates for SaaS vs. e-commerce). The methodology is framework-level, not benchmark-level.
**Attempted**: Searched for Maurya-provided benchmarks.
**Recommendation**: Supplement with industry benchmarking data from sources like First Round Capital, SaaS benchmarks reports, or Lean Analytics.

### Gap 3: Direct Running Lean to Agile/Scrum Mapping
**Issue**: While Lean Canvas is frequently discussed in agile contexts, Maurya himself does not prescribe a specific mapping from Lean Canvas to user stories/sprints. The integration in Section 6 of this research is an analytical interpretation.
**Attempted**: Searched for Maurya's own guidance on user story derivation.
**Recommendation**: The Product Backlog Building Canvas (Paulo Caroli, referenced on martinfowler.com) provides one bridge methodology. The integration model in Section 6 is consistent with the methodology but is not directly prescribed by Maurya.

## Conflicting Information

### Conflict 1: OMTM Origin Attribution
**Position A**: OMTM was originated by Ben Yoskovitz and Alistair Croll in *Lean Analytics* (2013). -- Source: [Lean Analytics Book](https://leananalyticsbook.com/one-metric-that-matters/), Reputation: 0.8
**Position B**: Some sources attribute OMTM thinking to Ash Maurya's work in Running Lean. -- Source: Various summary sites, Reputation: 0.6
**Assessment**: The OMTM concept was formalized and named by Yoskovitz/Croll. Maurya endorsed and integrated the concept (his blog post is titled "Lean Analytics -- The One Metric That Matters and Other Provocations"). The frameworks are complementary, not competitive. Maurya's contribution is the Customer Factory + Theory of Constraints approach to *selecting* which metric matters.

## Recommendations for Further Research

1. **Purchase Running Lean 3rd Edition** for access to complete templates, especially the Customer Forces Canvas, Traction Roadmap worksheets, and 90-day cycle planning tools.
2. **Research Scaling Lean** (Maurya's second book) for deeper treatment of the Customer Factory model, Fermi estimation for market sizing, and innovation accounting.
3. **Investigate Teresa Torres' Continuous Discovery Habits** for complementary experiment design methodology that bridges lean validation with ongoing product development (referenced in existing LeanUX research).
4. **Prototype the Lean Canvas input schema** (Section 7.1) in the AI product owner agent and test whether structured canvas input produces better requirements than unstructured problem statements.
