Purpose

目的

Guide product managers through calculating Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM) for a product idea by asking adaptive, contextually relevant questions. Use this to build defensible market size estimates backed by real-world citations, economic projections, and population data—essential for pitching to investors, securing budget, or validating product-market fit.
This is not a back-of-napkin guess—it's a structured, citation-backed analysis that withstands scrutiny.
通过提出自适应、贴合上下文的问题,引导产品经理为产品创意计算总可寻址市场(TAM)、可服务可用市场(SAM)和可服务可获得市场(SOM)。使用本方法构建有真实数据引用、经济预测和人口数据支撑的可靠市场规模估算——这是向投资者推介、争取预算或验证产品市场契合度的关键。
这绝非随手估算的数字——而是一套结构化、有数据引用支撑的分析方法,能够经得起严格推敲。

Key Concepts

核心概念

TAM/SAM/SOM Framework

TAM/SAM/SOM框架

The three-tier market sizing model:
Total Addressable Market (TAM):
  • The total market demand for a product or service
  • "If we captured 100% of the market, what's the revenue?"
  • Broadest possible market (no constraints)
Serviceable Available Market (SAM):
  • The segment of TAM your company can realistically target
  • Narrowed by geography, firmographics, demographics, or product constraints
  • "Who can we actually reach with our product?"
Serviceable Obtainable Market (SOM):
  • The portion of SAM you can realistically capture
  • Accounts for competition, market constraints, go-to-market capacity
  • "What can we capture in the next 1-3 years?"
三层市场规模模型:
总可寻址市场(Total Addressable Market,TAM):
  • 某产品或服务的整体市场需求
  • 「如果我们占据100%的市场,营收会是多少?」
  • 最宽泛的市场范围(无任何限制)
可服务可用市场(Serviceable Available Market,SAM):
  • 企业实际能够触达的TAM细分市场
  • 受地域、企业特征、人口统计或产品限制等因素收窄
  • 「我们的产品实际能够触达哪些用户?」
可服务可获得市场(Serviceable Obtainable Market,SOM):
  • 企业实际能够占据的SAM份额
  • 需考虑竞争情况、市场限制、上市推广能力
  • 「未来1-3年我们能够占据多少市场?」

Why This Works

本方法的优势

  • Top-down validation: TAM → SAM → SOM ensures estimates are grounded in reality
  • Investor-friendly: Standard framework VCs and execs understand
  • Citation-backed: Real data sources (Census, Statista, World Bank) add credibility
  • Adaptive: Questions adjust based on context (B2B vs. B2C, US vs. global, etc.)
  • 自上而下验证: TAM → SAM → SOM的流程确保估算贴合实际
  • 契合投资者需求: 是风险投资机构和高管普遍理解的标准框架
  • 数据引用支撑: 真实数据源(人口普查局、Statista、世界银行)提升可信度
  • 自适应调整: 问题会根据上下文调整(如B2B vs B2C、美国 vs 全球等)

Anti-Patterns (What This Is NOT)

反模式(本方法不适用的情况)

  • Not a single-number guess: "The market is $10B" without supporting data
  • Not static: Markets evolve—reassess annually
  • Not a substitute for customer validation: Market size ≠ product-market fit
  • 非单一数字猜测: 不能只说「市场规模为100亿美元」却无数据支撑
  • 非静态分析: 市场在不断演变——需每年重新评估
  • 不能替代客户验证: 市场规模 ≠ 产品市场契合度

When to Use This

适用场景

  • Pitching to investors or execs (need market size in deck)
  • Validating product ideas (is the market big enough?)
  • Prioritizing product lines (which has bigger opportunity?)
  • Setting growth targets (what's realistic to capture?)
  • 向投资者或高管推介(演示文稿中需包含市场规模数据)
  • 验证产品创意(市场规模是否足够大?)
  • 产品线优先级排序(哪条产品线的机会更大?)
  • 设定增长目标(实际可达成的目标是多少?)

When NOT to Use This

不适用场景

  • For internal tools with captive users (no external market)
  • Before defining the problem (market sizing requires clear problem space)
  • As the only validation (pair with customer research)

  • 面向内部 captive 用户的工具(无外部市场)
  • 未明确问题之前(市场规模估算需要清晰的问题范围)
  • 作为唯一的验证方式(需与客户研究结合使用)

本交互式技能最多提出4个自适应问题,每个步骤提供枚举式的上下文相关选项。Agent会根据之前的回答调整后续问题。

Step 0: Gather Context (Before Questions)

步骤0:收集上下文(提问前)

Agent suggests:
Before we begin, it's helpful to have product context. If available, please share:
For Your Own Product:
  • Website copy (homepage, product pages, value prop statements)
  • Marketing emails or landing pages
  • Product descriptions or positioning statements
  • Case studies or customer testimonials
  • Sales deck or pitch materials
If You Don't Have a Product Yet:
  • Find a similar or adjacent product (competitor or analog)
  • Copy their website homepage, product description, or landing page
  • We'll use this as a reference point for market sizing
You can paste this content directly, or we can proceed with a brief description.
Why this helps:
  • Marketing materials already contain target audience, pain points, and value props
  • Analyzing real content (yours or competitors') grounds the analysis in reality
  • You can benchmark against similar products' market positioning

Agent建议:
开始之前,提前准备产品相关上下文会有所帮助。如有可用信息,请分享:
针对已有产品:
  • 网站文案(首页、产品页、价值主张声明)
  • 营销邮件或着陆页
  • 产品描述或定位声明
  • 案例研究或客户推荐
  • 销售演示文稿或推介材料
针对尚未成型的产品:
  • 找到类似或相关的产品(竞品或同类产品)
  • 复制其网站首页、产品描述或着陆页内容
  • 我们将以此作为市场规模估算的参考依据
您可以直接粘贴上述内容,或简要描述产品信息后继续。
这样做的好处:
  • 营销材料中已包含目标受众、痛点和价值主张
  • 分析真实内容(自有或竞品)能让分析更贴合实际
  • 您可以对标同类产品的市场定位

Optional Helper Script (Deterministic Math)

可选辅助脚本(确定性计算)

If you already have population and ARPU numbers (or a TAM estimate), you can run a deterministic helper to compute TAM/SAM/SOM and generate a Markdown table. This script does not fetch data or write files.
bash
python3 scripts/market-sizing.py --population 5400000 --arpu 1000 --sam-share 30% --som-share 10%

如果您已掌握人口数量和ARPU(每用户平均收入)数据(或已有TAM估算值),可以运行确定性辅助脚本来计算TAM/SAM/SOM并生成Markdown表格。本脚本不会获取外部数据或写入文件。
bash
python3 scripts/market-sizing.py --population 5400000 --arpu 1000 --sam-share 30% --som-share 10%

Validation Questions

验证问题

  1. Does TAM align with industry reports? [Compare to 3rd-party market research]
  2. Is SAM realistically serviceable? [Can your GTM motion reach this segment?]
  3. Is SOM achievable given competition? [Is 5-15% market share realistic in 3 years?]

  1. TAM是否与行业报告一致? [与第三方市场研究数据对比]
  2. SAM是否具备实际可服务性? [您的GTM策略能否触达该细分市场?]
  3. 考虑竞争情况后SOM是否可达成? [3年内占据5-15%的SAM份额是否现实?]

Next Steps

Common Pitfalls

常见误区

Pitfall 1: TAM Without Citations

误区1:TAM无数据引用

Symptom: "The market is $50B" (no source)
Consequence: Can't defend the number to investors or execs.
Fix: Cite industry reports (Gartner, IBISWorld, Statista) with URLs.

症状: 只说「市场规模为500亿美元」却无来源
后果: 无法向投资者或高管证明该数字的可靠性。
解决方法: 引用行业报告(Gartner、IBISWorld、Statista)并附上链接。

Pitfall 2: SOM Equals SAM

误区2:SOM等于SAM

Symptom: "SAM is $5B, SOM is $5B" (assuming 100% capture)
Consequence: Unrealistic projection—no market has zero competition.
Fix: SOM should be 1-20% of SAM in Year 1-3, accounting for competition.

症状: 「SAM为50亿美元,SOM为50亿美元」(假设占据100%市场份额)
后果: 不切实际的预测——没有任何市场是零竞争的。
解决方法: 第1-3年的SOM应占SAM的1-20%,需考虑竞争情况。

Pitfall 3: No Population Estimates

误区3:无人口规模估算

Symptom: Only dollar amounts, no customer counts
Consequence: Can't build sales/marketing plans without knowing customer volume.
Fix: Always include population (e.g., "1.2M businesses" or "60K customers in Year 1").

症状: 仅提供金额,无客户数量
后果: 没有客户数量数据无法制定销售/营销计划。
解决方法: 始终包含人口规模数据(例如:「120万家企业」或「第1年6万家客户」)。

Pitfall 4: Static Assumptions

误区4:静态假设

Symptom: TAM/SAM/SOM calculated once, never updated
Consequence: Stale data as markets shift.
Fix: Reassess annually. Markets grow/shrink, competition changes, new data emerges.

症状: TAM/SAM/SOM仅计算一次,从未更新
后果: 市场变化导致数据过时。
解决方法: 每年重新评估。市场会增长/萎缩,竞争格局会变化,新数据会不断出现。

Pitfall 5: Ignoring GTM Constraints

误区5:忽略GTM限制

Symptom: "SOM is 50% of SAM in Year 1" (but no sales team)
Consequence: SOM isn't realistic given GTM capacity.
Fix: Ground SOM in GTM constraints (sales capacity, marketing budget, conversion rates).

症状: 「第1年SOM占据SAM的50%」但没有销售团队
后果: 考虑GTM能力后,SOM并不现实。
解决方法: SOM需基于GTM限制(销售能力、营销预算、转化率)制定。
