Product Discovery
Build products customers actually want. Apply Marty Cagan's Silicon Valley-tested framework to discover solutions that are valuable, usable, feasible, and viable.
When to Use This Skill
- New product development when validating what to build
- Feature prioritization to ensure you're solving real problems
- Pivot decisions when current direction isn't working
- Team alignment on what problems to solve
- Risk reduction before committing development resources
- Continuous discovery to maintain product-market fit
Methodology Foundation
| Aspect | Details | |--------|---------| | Source | Marty Cagan - Inspired (2008, 2018) and Empowered (2020) | | Core Principle | "Fall in love with the problem, not the solution. The best product teams discover what customers need, not just what they ask for." | | Why This Matters | Most products fail not because they're built poorly, but because they solve the wrong problem. Discovery ensures you build the right thing before you build the thing right. |

What This Skill Does
- Frames the four risks - Value, usability, feasibility, viability
- Distinguishes discovery from delivery - Different mindsets, different processes
- Teaches opportunity assessment - Which problems to solve
- Develops prototyping skills - Test ideas before building
- Guides customer research - Learn what customers need (not want)
- Structures continuous discovery - Ongoing learning, not one-time research
How to Use
Assess a Product Opportunity
I'm considering building [feature/product].
Apply product discovery principles to assess this opportunity.
Context: [target customer, current state, hypothesis]
Reduce Risk Before Building
We're about to build [feature].
Help me identify the key risks and design tests to address them.
Set Up Continuous Discovery
I want to implement continuous discovery for my product team.
Help me design a weekly discovery rhythm.
Instructions
Step 1: Understand the Four Risks
## The Four Product Risks
Every product idea has four risks to address BEFORE building:
### 1. Value Risk
"Will customers buy/use this?"
**Questions:**
- Does this solve a real problem?
- Is the problem painful enough to pay/switch for?
- Will users actually adopt this?
**Tests:**
- Customer interviews
- Demand testing
- Fake door tests
- Concierge MVP
### 2. Usability Risk
"Can customers figure out how to use it?"
**Questions:**
- Is it intuitive?
- Can users accomplish their goals?
- What's the learning curve?
**Tests:**
- Prototype testing
- Usability studies
- Wizard of Oz tests
- A/B tests on UX
### 3. Feasibility Risk
"Can we build this?"
**Questions:**
- Do we have the technology?
- Can we do it in reasonable time?
- What are the technical dependencies?
**Tests:**
- Technical spike
- Proof of concept
- Architecture review
- Build vs. buy analysis
### 4. Viability Risk
"Should we build this?"
**Questions:**
- Does it fit our strategy?
- Can we support/maintain it?
- Is it legal/compliant?
- Does the business model work?
**Tests:**
- Business case
- Stakeholder review
- Compliance review
- Financial modeling
Step 2: Discovery vs. Delivery
## Two Tracks: Discovery and Delivery
### Discovery (Figure out WHAT to build)
**Mindset:**
- Embrace uncertainty
- Test assumptions
- Fail fast and cheap
- Learn over deliver
**Activities:**
- Customer interviews
- Prototyping
- Experiments
- Opportunity assessment
**Outcome:**
- Validated problems
- Tested solutions
- Confidence to build
- Clear success metrics
### Delivery (BUILD it right)
**Mindset:**
- Reduce uncertainty
- Execute efficiently
- Ship quality
- Hit timelines
**Activities:**
- Engineering
- QA
- Launch prep
- Documentation
**Outcome:**
- Working software
- Happy customers
- Business impact
- Technical quality
### The Critical Point
Most teams skip discovery and jump to delivery.
**Result:**
- Build features no one wants
- Waste engineering resources
- Miss market opportunities
- Frustrated team, frustrated customers
**The ratio:**
Spend 10-20% of time on discovery to avoid wasting
80-90% of delivery time on wrong things.
Step 3: Opportunity Assessment
## Assessing Product Opportunities
### The Opportunity Assessment Framework
Before committing to solve a problem, answer:
**1. Is this problem worth solving?**
| Factor | Questions |
|--------|-----------|
| **Frequency** | How often does this problem occur? |
| **Intensity** | How painful is it when it happens? |
| **Willingness** | Will people pay/switch to solve it? |
| **Reach** | How many customers have this problem? |
**Scoring:**
- High frequency + High intensity = Strong opportunity
- Low frequency OR Low intensity = Weak opportunity
**2. Can we solve it effectively?**
| Factor | Questions |
|--------|-----------|
| **Capability** | Do we have the skills/tech? |
| **Fit** | Does it align with our strategy? |
| **Uniqueness** | Can we solve it better than alternatives? |
| **Sustainability** | Can we maintain competitive advantage? |
**3. Should we solve it now?**
| Factor | Questions |
|--------|-----------|
| **Urgency** | Is timing critical? |
| **Resources** | Do we have capacity? |
| **Dependencies** | What else needs to happen first? |
| **Opportunity cost** | What are we NOT doing instead? |

Step 4: Discovery Techniques
## Core Discovery Techniques
### 1. Customer Interviews
**Purpose:** Understand problems, not validate solutions
**Structure:**
1. Context: Understand their current situation
2. Problem: Explore the pain points
3. Impact: How does it affect them?
4. Current solutions: What do they do today?
5. Ideal state: What would "solved" look like?
**Key rules:**
- Ask about past behavior, not future intentions
- Don't pitch, just listen
- Follow the emotion
- Get specific stories
**Questions:**
- "Walk me through the last time this happened..."
- "What did you do? What happened next?"
- "Why was that a problem?"
- "What would have made it better?"
### 2. Prototyping
**Purpose:** Test solutions before building
**Types:**
| Type | Fidelity | Tests | Time |
|------|----------|-------|------|
| **Paper sketch** | Low | Concepts, flow | Hours |
| **Wireframe** | Low-Med | Structure, navigation | Days |
| **Clickable prototype** | Medium | Usability, flow | Days |
| **Wizard of Oz** | High | Full experience | Weeks |
**Principle:**
Use the lowest fidelity that tests your hypothesis.
Higher fidelity = More time = More risk of attachment.
### 3. Experiments
**Purpose:** Test assumptions with real behavior
**Types:**
- **Fake door:** Button for feature that doesn't exist
- **Smoke test:** Landing page before building
- **Concierge:** Manual delivery of automated value
- **A/B test:** Compare variations with real users
**Structure:**
1. Hypothesis: "We believe [X]"
2. Test: "We will test by [Y]"
3. Metric: "We will measure [Z]"
4. Success: "[Number] indicates we should proceed"
