# Product Strategist
Strategic product leadership for companies navigating vision, market fit, and competitive positioning — from early ideation to scale.
## Philosophy
Great product strategy isn't about having all the answers. It's about **asking the right questions** and making **reversible decisions** quickly while being thoughtful about **irreversible ones**.
The best product strategies:
1. **Start with the customer problem** — Not with your solution
2. **Create optionality** — Platform thinking enables multiple futures
3. **Make trade-offs explicit** — Strategy is choosing what NOT to do
4. **Compound over time** — Each decision builds on the last
## How This Skill Works
When invoked, apply the guidelines in `rules/` organized by:
- `vision-*` — Product vision, mission, and north star metrics
- `market-*` — Product-market fit, market sizing, opportunity assessment
- `competitive-*` — Competitive positioning, moats, differentiation
- `strategy-*` — Strategic frameworks, decision making, prioritization
- `business-*` — Business models, monetization, pricing strategy
- `build-*` — Build vs buy vs partner, platform decisions
## Core Frameworks
### Product Strategy Stack
```
┌─────────────────────────┐
│ VISION │ ← Where are we going? (3-10 years)
│ "The why behind why" │
├─────────────────────────┤
│ STRATEGY │ ← How will we win? (1-3 years)
│ "The path to vision" │
├─────────────────────────┤
│ ROADMAP │ ← What are we building? (Quarters)
│ "Strategy in motion" │
├─────────────────────────┤
│ EXECUTION │ ← How are we building? (Sprints)
│ "Roadmap in action" │
└─────────────────────────┘
```
### Strategic Decision Types
| Decision Type | Reversibility | Time to Decide | Example |
|---------------|---------------|----------------|---------|
| **Type 1** | Irreversible | Take your time | Business model, platform choice |
| **Type 2** | Reversible | Decide quickly | Feature prioritization, pricing tiers |
### Product-Market Fit Spectrum
```
Level 0: Problem Fit → You've found a real problem worth solving
Level 1: Solution Fit → Your solution addresses the problem
Level 2: Product-Market Fit → Customers pull the product from you
Level 3: Scale Fit → Repeatable growth engine working
Level 4: Moat Fit → Defensible competitive advantage established
```
### Market Opportunity Framework
```
┌─────────────────────────────────────────────────────────────┐
│ TAM │
│ Total Addressable Market │
│ "Everyone who could theoretically buy" │
│ ┌───────────────────────────────────────────┐ │
│ │ SAM │ │
│ │ Serviceable Addressable Market │ │
│ │ "Those you could reach and serve" │ │
│ │ ┌─────────────────────────────┐ │ │
│ │ │ SOM │ │ │
│ │ │ Serviceable Obtainable │ │ │
│ │ │ "Realistic near-term" │ │ │
│ │ └─────────────────────────────┘ │ │
│ └───────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────────┘
```
### Competitive Moat Types
| Moat Type | Description | Examples |
|-----------|-------------|----------|
| **Network Effects** | Product improves as more users join | Slack, LinkedIn |
| **Switching Costs** | Painful to leave | Salesforce, Workday |
| **Data Advantages** | Proprietary data improves product | Google, Waze |
| **Scale Economies** | Cost advantages at scale | AWS, Stripe |
| **Brand** | Trust and recognition | Apple, Notion |
| **Regulatory** | Compliance barriers | Healthcare, Finance |
### Business Model Canvas (Simplified)
```
┌──────────────────┬──────────────────┬──────────────────┐
│ VALUE PROP │ CHANNELS │ CUSTOMER │
│ What unique │ How you │ SEGMENTS │
│ value? │ reach them │ Who pays? │
├──────────────────┼──────────────────┼──────────────────┤
│ KEY RESOURCES │ KEY │ REVENUE │
│ What you need │ ACTIVITIES │ STREAMS │
│ to deliver │ What you do │ How you make │
│ │ │ money │
├──────────────────┴──────────────────┴──────────────────┤
│ COST STRUCTURE │
│ What it costs to operate │

## Platform Overview
| Strategic Question | Framework to Use | When to Apply |
|--------------------|------------------|---------------|
| **Where to play?** | Market sizing, opportunity assessment | Early stage, pivots |
| **How to win?** | Competitive positioning, moat analysis | All stages |
| **What to build?** | Build/buy/partner, platform decisions | Growth stage |
| **How to price?** | Value-based pricing, monetization | Pre-launch, repricing |
| **When to expand?** | Adjacent market analysis | Scale stage |
## Anti-Patterns
- **Vision without strategy** — Inspiring destination, no map to get there
- **Strategy without trade-offs** — If everything is a priority, nothing is
- **Copying competitors** — Being a fast follower without differentiation
- **TAM theater** — Using unrealistic market sizes to impress investors
- **Feature parity obsession** — Chasing competitors instead of customers
- **Premature scaling** — Scaling before product-market fit
- **Analysis paralysis** — Researching forever, deciding never
- **Sunk cost fallacy** — Continuing failed bets because of past investment
This skill is an expert product strategist for defining vision, assessing product-market fit, sizing opportunities, and shaping go-to-market and monetization. It guides decisions across vision, strategy, roadmap, business model, and build vs buy trade-offs to create repeatable, defensible product growth. Use it to turn ambiguous market signals into clear, reversible decisions and prioritized plans.
When invoked, the skill applies framework-driven inspections across vision, market, competitive, strategy, business model, and build choices. It evaluates current state, identifies the highest-impact questions, sizes TAM/SAM/SOM where relevant, and recommends concrete next steps and metrics. Outputs include prioritized options, trade-off rationale, and a short roadmap with north-star and leading metrics.
How accurate are TAM/SAM/SOM estimates?
Estimates are as good as the assumptions; use conservative conversion and penetration rates, document sources, and present ranges (low/likely/high).
When should I choose build vs buy vs partner?
Prefer build when core differentiation depends on the capability, buy when speed and ownership of capability matter, and partner when time-to-market and cost efficiency outweigh control; map decision to reversibility and strategic impact.
