Series: Idea Sourcing & Validation (Part 3 of 4)
Series Navigation:
Progressive validation frameworks provide structure. But what methodologies do studios actually use to test hypotheses and validate assumptions?
While the five-stage framework (from Part 2) defines when to validate, specific methodologies define how to validate. The best studios don't invent validation approaches from scratch—they systematically apply proven methodologies from the startup and product development world.
This article explores four core validation methodologies that studios use in practice:
Lean Startup - Build-Measure-Learn cycles
Customer Discovery - Systematic customer interviews
DVF Framework - Desirability-Viability-Feasibility testing
Demand Testing - Measuring actual customer intent
Understanding these tools gives studios (and founders) a practical toolkit for de-risking ideas systematically.
Methodology 1: Lean Startup Approach
The Lean Startup methodology, pioneered by Eric Ries, provides the foundation for how most studios approach validation.
Core Lean Startup Principles
1. Build-Measure-Learn Cycle
The fundamental loop:
Build: Create minimum viable experiment
Measure: Collect data on key metrics
Learn: Analyze results and decide next steps
The goal: Complete this cycle as quickly and cheaply as possible.
2. Validated Learning
Progress isn't measured by:
Features built
Code written
Plans created
Time invested
Progress is measured by:
Hypotheses tested
Assumptions validated
Customer insights gained
Learning achieved
3. Minimum Viable Product (MVP)
Not: The smallest product you can build Rather: The smallest experiment to test a hypothesis
MVPs can be:
Landing pages (test demand)
Concierge service (test solution manually)
Wizard of Oz (fake automation)
Prototypes (test usability)
Explainer videos (test understanding)
How Studios Apply Lean Startup
Stage-by-Stage Application:
Pre-Validation Stage:
Hypothesis: "SMB owners struggle with cash flow management"
MVP: Interview 10 SMB owners
Measure: Pain level, current solutions, willingness to change
Learn: Problem severity, urgency, target segment
Validation Stage:
Hypothesis: "SMBs will use a simple dashboard to track cash flow"
MVP: Mockup or prototype walkthrough
Measure: Comprehension, perceived value, WTP
Learn: Feature priorities, pricing sensitivity, positioning
MVP/Launch Stage:
Hypothesis: "SMBs will pay $99/month for cash flow tool"
MVP: Functional basic product
Measure: Signups, activation, retention, NPS
Learn: Product-market fit signals, iteration priorities
Key Lean Startup Techniques Studios Use
1. Pivot or Persevere Decisions
Regular decision points to:
Pivot: Change fundamental hypothesis
Persevere: Continue current approach
Iterate: Make incremental improvements
Types of pivots:
Customer segment pivot
Problem pivot
Solution pivot
Channel pivot
Business model pivot
2. Innovation Accounting
Measuring progress through:
Leading indicators (engagement, activation)
Cohort analysis
Learning milestones
Validated learning rate
Not vanity metrics (total users, downloads, page views without context)
3. Split Testing
Even in validation:
Two messaging approaches
Different pricing points
Various value propositions
Alternative solutions
Small tests reveal preferences.
When Lean Startup Works Best
Ideal for:
Software and digital products
B2C and prosumer markets
Short feedback cycles
Iterative product development
Uncertain problem spaces
Less applicable for:
Long sales cycles (enterprise)
Regulated industries (slow iteration)
Hardware (expensive iteration)
Deep tech (long development)
Methodology 2: Customer Discovery Process
Developed by Steve Blank, Customer Discovery provides systematic frameworks for understanding customers before building products.
The Customer Discovery Philosophy
Core belief: Get out of the building and talk to customers.
Traditional approach:
Build product based on assumptions
Launch to market
Hope customers buy
Customer Discovery approach:
Talk to 50-100 potential customers
Understand problem deeply
Validate solution before building
Iterate until product-market fit
The Four-Step Framework
Step 1: State Your Hypotheses
Document assumptions about:
Customer hypotheses:
Who has the problem?
How painful is it?
How do they solve it today?
What triggers the need?
Problem hypotheses:
What is the core problem?
Why does it exist?
What are consequences?
What would "solved" look like?
Solution hypotheses:
What will solve the problem?
Why is our approach better?
What's the minimum viable solution?
What features matter most?
Business model hypotheses:
How will we make money?
What will customers pay?
How do we acquire customers?
What are unit economics?
Step 2: Test Problem Understanding
Conduct problem interviews (15-25):
Goals:
Understand customer's world
Identify pain points
Learn current solutions
Assess problem severity
Validate or invalidate hypotheses
Key questions:
Walk me through [relevant process/task]
What's frustrating about that?
How do you handle it today?
What have you tried?
If you could wave a magic wand...?
What you're listening for:
Urgency signals
Frequency of problem
Economic impact
Emotional language
Current solution inadequacy
Step 3: Test Solution Fit
Conduct solution interviews (25-50):
Show, don't just tell:
Mockups or prototypes
Explainer videos
Detailed descriptions
Competitor comparisons
Goals:
Validate solution resonates
Understand feature priorities
Test messaging and positioning
Assess willingness to pay
Identify objections
Key questions:
How would this help you?
What would you change?
What's most valuable?
What's missing?
What would you pay for this?
Red flags:
Polite interest without excitement
"Nice to have" not "must have"
Lots of feature requests
Can't articulate value clearly
Won't commit to trying it
Step 4: Verify Viability
Final validation before building:
Letters of intent (LOIs)
Pre-orders or commitments
Pilot agreements
Beta tester recruitment
Channel partner interest
The goal: Demonstrate actual commitment, not just interest.
Customer Interview Best Practices
The Mom Test (Rob Fitzpatrick):
Don't ask:
"Would you use this?"
"Is this a good idea?"
"Would you pay for this?"
People lie to be nice.
Instead ask:
"Tell me about last time you [experienced problem]"
"How do you handle that today?"
"What does that cost you?"
"When was the last time you bought something to solve this?"
Focus on past behavior, not future intentions.
Interview Structure:
Opening (5 min):
Build rapport
Explain purpose
Set expectations
Get permission to record
Problem exploration (20 min):
Their world and workflow
Pain points and frustrations
Current solutions
Attempted alternatives
Solution testing (15 min):
Show concept/prototype
Get reactions and feedback
Feature prioritization
Willingness to pay
Close (5 min):
Ask for referrals
Next steps if applicable
Thank them
Key skills:
Shut up and listen
Dig into specifics
Follow interesting threads
Challenge yourself to kill idea
Take detailed notes
When Customer Discovery Works Best
Ideal for:
B2B opportunities
Complex problem spaces
New market creation
Solution uncertainty
Need deep customer insights
Less critical for:
Well-understood markets
Copycat businesses
Platform/ecosystem plays
Technical capability validation
Methodology 3: DVF Framework (Desirability-Viability-Feasibility)
The DVF Framework, popularized by IDEO and design thinking, ensures holistic validation across three dimensions.
The Three DVF Dimensions
Desirability: Do people want this?
Customer problem and need
Solution attractiveness
User experience quality
Emotional resonance
Competitive positioning
Viability: Can we build a business?
Business model sustainability
Unit economics
Market size
Revenue potential
Profitability path
Feasibility: Can we actually build it?
Technical capability
Resource requirements
Timeline realism
Regulatory approval
Operational complexity
All three must be validated. One dimension isn't enough.
How Studios Apply DVF
Desirability Validation:
Methods:
Customer interviews and surveys
Prototype testing
Demand testing (landing pages)
Usage analytics (if MVP exists)
Net Promoter Score
Questions to answer:
Do customers have this problem?
Is our solution compelling?
Do they prefer it to alternatives?
Would they recommend it?
What's the emotional response?
Evidence needed:
Strong problem urgency
Solution resonance
Preference over alternatives
Willingness to switch
Emotional engagement
Viability Validation:
Methods:
Business model canvas
Unit economics modeling
Market sizing analysis
Competitive benchmarking
Pricing research
Questions to answer:
Is the market large enough?
Can we acquire customers profitably?
What will people actually pay?
What are our costs?
Is there a path to profitability?
Evidence needed:
Significant TAM/SAM
Reasonable CAC estimates
Pricing that supports margins
Scalable business model
Clear path to positive economics
Feasibility Validation:
Methods:
Technical proof of concept
Resource planning
Regulatory pathway analysis
Partner capability assessment
Timeline modeling
Questions to answer:
Can we build this technically?
Do we have necessary capabilities?
Are timelines realistic?
What are dependencies?
What could block us?
Evidence needed:
Technical approach proven
Team capabilities confirmed
Resources available or accessible
No fatal regulatory blockers
Realistic timeline
DVF in Practice: Example
Opportunity: AI-powered contract review for law firms
Desirability Validation:
Interview 30 attorneys about contract review pain
Test willingness to trust AI
Show prototype interface
Assess feature priorities
Measure excitement level
Findings:
✅ Strong pain point identified
✅ Willingness to try AI assistance
⚠️ Need human-in-loop, not replacement
✅ Clear feature priorities
✅ High interest level
Viability Validation:
Size market (law firms, contract volume)
Research legal tech pricing
Model customer acquisition costs
Calculate unit economics
Assess competitive landscape
Findings:
✅ Large addressable market
✅ Pricing supports margins ($500-2000/month)
⚠️ CAC moderately high (enterprise sales)
✅ Unit economics work at scale
⚠️ Competitive but differentiated
Feasibility Validation:
Validate AI/ML approach
Assess training data availability
Evaluate regulatory considerations
Confirm team capabilities
Model development timeline
Findings:
✅ Technical approach validated
⚠️ Training data requires partnerships
⚠️ Regulatory compliance complex but manageable
✅ Team has core capabilities
⚠️ 9-12 month MVP timeline
Decision: Proceed with MVP, address warnings during build
When DVF Framework Works Best
Ideal for:
Complex opportunities
Technical products
Regulated industries
New market creation
Comprehensive assessment needed
The framework ensures no dimension is forgotten.
Methodology 4: Demand Testing
The most direct validation: measure actual customer behavior, not stated intentions.
The Philosophy of Demand Testing
People lie about future behavior (usually unintentionally):
"I would totally buy that"
"That sounds useful"
"Let me know when it's ready"
Behavior reveals truth:
Click this link
Enter email address
Pre-order now
Start free trial
Sign contract
Demand testing measures actual behavior, not opinions.
Common Demand Testing Approaches
1. Landing Page Testing
The method:
Create landing page describing product
Explain value proposition
Call to action (email signup, waitlist, pre-order)
Drive traffic (paid ads, organic, partnerships)
Measure conversion rates
What you're testing:
Is value proposition clear?
Does it resonate with audience?
Do people take action?
What messaging works?
What price sensitivity exists?
Success criteria vary:
B2B SaaS: 5-10% email capture reasonable
Consumer: 10-20% for strong demand
Pre-orders: 1-3% excellent signal
2. Smoke Testing
The method:
Build appearance of product (landing page, mockups)
Accept "orders" or signups
Don't actually build product yet
Measure how many people try to buy
Refund or waitlist those who try
More aggressive than landing page testing.
Example: Drew Houston (Dropbox) created video demo before building product. Video on Hacker News generated 75,000 signups overnight.
3. Concierge MVP
The method:
Manually deliver the service
No technology built yet
Founder/team does work by hand
Customers pay real money
Learn what actually delivers value
Classic example: Food delivery service where founders take orders via email and personally buy/deliver food before building platform.
Benefits:
Real customer relationships
Deep understanding of workflow
Willingness to pay validated
Feature priorities revealed
Sustainable business model tested
4. Wizard of Oz Testing
The method:
Product appears automated
But humans do work behind scenes
Customer doesn't know
Tests solution before building technology
Validates if automation worth building
Example: AI chatbot that's actually humans responding (customer thinks it's AI). Validates if automated version worth building.
5. Pre-Sales and LOIs
The method:
Sell product before building
Letters of Intent (LOIs) from customers
Paid pilots or POCs
Pre-orders with deposits
Commitment before creation
Gold standard for B2B validation.
What LOIs should include:
Specific commitment ("will purchase")
Timeline for purchase
Approximate budget/pricing
Signature from decision-maker
Not just "interested in learning more"
Demand Testing Best Practices
1. Make It Real
Not: "Would you hypothetically buy this?" Instead: "Buy it now" (even if pre-order)
The harder the commitment, the better the signal.
Commitment Ladder:
Expressed interest: Weak signal
Email address: Weak-moderate signal
Waitlist signup: Moderate signal
Pre-order with refund: Strong signal
Paid pilot/POC: Very strong signal
Signed contract: Strongest signal
2. Measure Conversion, Not Just Traffic
1,000 visitors, 5 emails: Weak
100 visitors, 15 emails: Strong
Quality over quantity
3. Test Multiple Variations
Different value propositions
Various price points
Alternative messaging
Different customer segments
Learn what resonates.
4. Follow Up
When people express interest:
Interview them
Understand their needs
Learn why they signed up
Test solution concepts
Convert to early customers
5. Be Honest and Transparent
When testing:
Don't mislead customers
Explain product not ready yet
Offer refunds easily
Maintain trust
Build early believers
When Demand Testing Works Best
Ideal for:
Consumer products
Products with network effects
New categories (need validation)
Testing messaging/positioning
Measuring pricing sensitivity
Less applicable for:
Enterprise sales (long cycles)
Complex B2B (need education)
Regulated products (can't pre-sell)
Services requiring licenses
Combining Methodologies
The most effective studios don't choose one methodology—they combine them strategically.
Multi-Method Validation Example
Opportunity: Project management tool for architects
Phase 1: Customer Discovery (Weeks 1-4)
Interview 20 architects about workflow
Understand pain points
Map current solutions
Identify biggest frustrations
Learning: Collaboration with contractors is biggest pain
Phase 2: Lean Startup MVP (Weeks 5-8)
Create clickable prototype
Show to 15 architects
Test key workflows
Iterate based on feedback
Learning: Specific features resonate, others don't matter
Phase 3: DVF Validation (Weeks 9-10)
Desirability: Validated through interviews and prototype
Viability: Model economics, market size
Feasibility: Assess technical requirements
Learning: All three dimensions validated
Phase 4: Demand Testing (Weeks 11-12)
Create landing page
Run targeted LinkedIn ads
Offer early access
Measure signups and engagement
Learning: 8% conversion rate, strong signal
Phase 5: Concierge MVP (Weeks 13-20)
Manually manage projects for 5 firms
Charge real fees
Learn actual workflow
Identify automation opportunities
Learning: WTP validated, feature priorities clear, ready to build
Result: High confidence before building scaled product
