Product Strategy

Product Vision Framework

VISION COMPONENTS:

TARGET CUSTOMER:
- Who are we building for?
- What segments? What personas?

CUSTOMER NEED:
- What problem are we solving?
- What job to be done?

KEY BENEFIT:
- Primary value proposition
- Why customers will choose us

DIFFERENTIATOR:
- What makes us unique?
- Competitive advantage

AMAZON PRESS RELEASE FORMAT:
- Headline
- Summary (who, what, when, where, why)

Product-Market Fit

PMF INDICATORS:

QUANTITATIVE:
- 40%+ would be "very disappointed" without product (Sean Ellis)
- Strong organic growth/referrals
- Low churn, high retention
- Improving unit economics

QUALITATIVE:
- Customers actively advocating
- Word of mouth driving acquisition
- Pull from market (not push)
- Customers expanding usage

PMF SURVEY:
"How would you feel if you could no longer use [product]?"
- Very disappointed → Target 40%+
- Somewhat disappointed
- Not disappointed

PMF STAGES:
1. Problem-Solution Fit: Validated problem worth solving
2. Product-Market Fit: Solution resonates with market
3. Business Model Fit: Sustainable economics
4. Scale: Growth mechanics work

Jobs to Be Done (JTBD)

JOB STATEMENT:
When [situation], I want to [motivation], so I can [expected outcome].

FORCES OF PROGRESS:
Push: Current pain/frustration
Pull: Attraction to new solution
Anxiety: Concerns about switching
Habit: Comfort with status quo

See Customer Research Methods for detailed JTBD methodology and interview techniques.

Roadmap Planning

Roadmap Types

OKR Framework for Product

PRODUCT OKR STRUCTURE:

OBJECTIVE: [Qualitative goal]

KEY RESULT 1: [Metric] from [X] to [Y]
KEY RESULT 2: [Metric] from [X] to [Y]
KEY RESULT 3: [Metric] from [X] to [Y]

EXAMPLE:
O: Become the preferred solution for enterprise customers
KR1: Increase enterprise NPS from 40 to 60
KR2: Reduce enterprise churn from 8% to 4%
KR3: Increase enterprise ACV from $50K to $75K

Feature Prioritization

RICE Framework

RICE SCORE = (Reach x Impact x Confidence) / Effort

REACH: How many customers affected per quarter
- Count: Number of users, customers, transactions

IMPACT: Effect on individual customer
- 3 = Massive
- 2 = High
- 1 = Medium
- 0.5 = Low
- 0.25 = Minimal

CONFIDENCE: How sure are we
- 100% = High confidence
- 80% = Medium
- 50% = Low

EFFORT: Person-months of work
- Engineering time
- Design time
- PM time

EXAMPLE:
| Feature | Reach | Impact | Conf | Effort | RICE |
|---------|-------|--------|------|--------|------|
| A | 5000 | 2 | 80% | 3 | 2667 |
| B | 1000 | 3 | 100% | 1 | 3000 |
| C | 10000 | 1 | 50% | 5 | 1000 |

ICE Framework

ICE SCORE = Impact x Confidence x Ease

IMPACT (1-10):
How much will this move our key metric?

CONFIDENCE (1-10):
How sure are we about impact estimate?

EASE (1-10):
How easy to implement?

Note: Simpler than RICE, good for quick decisions

MoSCoW Method

Kano Model

CATEGORIES:

BASIC (Must-be):
- Expected features
- Absence causes dissatisfaction
- Example: Login functionality

PERFORMANCE (Linear):
- More is better
- Satisfaction proportional to fulfillment
- Example: Speed, capacity

DELIGHTERS (Excitement):
- Unexpected features
- Absence doesn't cause dissatisfaction
- Presence greatly increases satisfaction
- Example: Innovative features

Customer Research

Research Methods

See Customer Research Methods for detailed interview frameworks, persona templates, and usability testing protocols.

Product Analytics

Key Metrics Framework

PIRATE METRICS (AARRR):

ACQUISITION:
- How do users find us?
- Metrics: Traffic, signups, installs

ACTIVATION:
- First positive experience
- Metrics: Onboarding completion, first value

RETENTION:
- Do they come back?
- Metrics: DAU/MAU, cohort retention

REVENUE:
- Do they pay?
- Metrics: Conversion, ARPU, LTV

REFERRAL:
- Do they tell others?
- Metrics: NPS, referral rate, viral coefficient

Product Health Metrics

See Analytics and Experimentation for detailed cohort analysis, retention benchmarks, and event tracking strategies.

A/B Testing

Experiment Framework

EXPERIMENT DESIGN:

HYPOTHESIS:
If we [change], then [metric] will [improve/decrease] because [rationale].

METRICS:
- Primary: The metric you're trying to move
- Secondary: Other metrics to monitor
- Guardrails: Metrics that shouldn't degrade

SAMPLE SIZE:
Use calculator based on:
- Baseline conversion rate
- Minimum detectable effect (MDE)
- Statistical significance (usually 95%)
- Power (usually 80%)

DURATION:
- At least 1 business cycle
- Adequate sample size
- Account for novelty effects

Decision Framework

• Ship: Stat sig + practical sig + no negative guardrails
• Iterate: Directionally positive but not stat sig, or mixed results
• Kill: No effect or negative impact
• Investigate: Unexpected results, large variance, segment differences

See Analytics and Experimentation for detailed statistical concepts, common pitfalls, and segmentation analysis.
