What is TAM, SAM, and SOM?

TAM is the Total Addressable Market, SAM is the Serviceable Addressable Market, and SOM is the Serviceable Obtainable Market. They are used to quantify overall opportunity, reachable segments, and realistically capturable share.

What data sources should I use for market sizing?

Use industry reports, government statistics, trade association data, and analyst data to estimate market sizes, and clearly document each source.

What is the expected output of this skill?

A market-opportunity report conforming to the template, saved as 01-sources/[YYYYMMDD]-market-opportunity-v0.md, and referencing references/market-opportunity-template.md.

Market Opportunity Analysis Skill

This skill provides rigorous market sizing and opportunity analysis using the TAM/SAM/SOM framework to quantify addressable markets.

Theoretical Foundation

TAM/SAM/SOM Framework

pie title Market Sizing Framework
    "TAM (Total)" : 100
    "SAM (Serviceable)" : 30
    "SOM (Obtainable)" : 5

Metric	Definition	Question
TAM	Total Addressable Market	How big is the universe?
SAM	Serviceable Addressable Market	What can we reach?
SOM	Serviceable Obtainable Market	What can we realistically capture?

Sizing Approaches

Top-Down: Start with industry data, narrow down
Bottom-Up: Build from unit economics and segments
Value Theory: Calculate value created for customers

When to Use

New product evaluation
Investor presentations
Market entry decisions
Strategic planning
Resource allocation

Instructions

Step 1: Configuration

Read .claude/AGENTS.md for preferences
Identify product/service to analyze
Define geographic and temporal scope

Step 2: Define Market Context

What problem does the product solve?
Who experiences this problem?
What is the current spending in this area?

Step 3: Calculate TAM

Research total market size:

Industry reports and analyst data
Government statistics
Trade association data
Calculate: Total potential customers × Average spend

Step 4: Calculate SAM

Narrow to serviceable market:

Geographic limitations
Segment focus
Distribution capabilities
Technology requirements

Step 5: Calculate SOM

Estimate realistic capture:

Competitive intensity
Go-to-market capability
Time horizon (1-3 years)
Historical benchmarks

Step 6: Identify Market Gaps

Analyze opportunities:

Underserved segments
Unmet needs
Competitive weaknesses
Emerging trends

Step 7: Generate Report

Overview

This skill provides rigorous market sizing and opportunity analysis using the TAM/SAM/SOM framework to quantify addressable markets. It guides you through defining scope, calculating TAM/SAM/SOM, identifying gaps, and generating a formal report for stakeholders.

How This Skill Works

It applies three sizing approaches (top-down, bottom-up, value theory) to compute TAM, SAM, and SOM. It then outputs a structured market-opportunity report aligned with the provided template, including executive summary, market definition, and key opportunities.

When to Use It

New product evaluation
Investor presentations
Market entry decisions
Strategic planning
Resource allocation

Quick Start

Step 1: Configuration — read preferences, identify product/service, and set geographic/temporal scope.
Step 2: Compute TAM/SAM/SOM — gather data (industry reports, government stats), apply top-down/bottom-up/value-theory methods, derive numbers.
Step 3: Output report — assemble executive summary, market definition, TAM/SAM/SOM analyses, market dynamics, and recommendations in the prescribed file path and template.

Best Practices

Configure scope and preferences early (per .claude/AGENTS.md), identify the product/service, and define geographic/temporal scope.
Use multiple sizing approaches: Top-Down, Bottom-Up, and Value Theory to triangulate TAM/SAM/SOM.
Ground TAM in data: industry reports, government statistics, trade associations, and analyst data; document sources.
Define SAM with geographic/segment constraints and technology/distribution requirements; adjust for serviceability.
Record assumptions, time horizons, and go-to-market capabilities; generate the final report using the prescribed template.

Example Use Cases

Evaluate a new software product's market potential using TAM/SAM/SOM and present a CEO-ready market opportunity section with sources.
Prepare an investor deck that includes TAM/SAM/SOM with methodology and assumptions.
Conduct a market-entry analysis for a new region, defining scope, data sources, and moat considerations.
Assess resource allocation for a strategic product initiative by estimating addressable market and growth opportunities.
Generate the market-opportunity report at 01-sources/[YYYYMMDD]-market-opportunity-v0.md using references/market-opportunity-template.md.
