nahisaho Market Scan
Market landscape analysis with TAM/SAM/SOM and trend signals.
Use This Skill When
- Sizing TAM/SAM/SOM for a target market.
- Identifying demand trends and growth drivers.
- Building market landscape summaries.
Workflow
- Define market boundaries (geography, segment, time period).
- Size TAM (top-down from industry reports) and SAM/SOM (bottom-up from target capability).
- Identify key trends (macro, technology, regulatory, consumer).
- Document sources with trust levels.
- Save to files.
Deliverables
results/market-scan.md: market landscape with TAM/SAM/SOM.- Reuse
assets/market-scan-template.mdwhen producing standardized market analyses.
Quality Gates
- TAM/SAM/SOM documented with sources and methodology (top-down/bottom-up).
- Key trends identified with supporting evidence.
- All data labeled: Fact / Estimate / Assumption.
- Confidence levels on estimates.
If any gate fails: identify the issue, fix, and re-validate.
Gotchas
- TAM と SAM を混同しないこと。TAM=全市場、SAM=自社がアクセス可能な市場
- 市場規模の推定方法（Top-down vs Bottom-up）を必ず明記すること。方法が異なると数値が大きく変わる
- 成長率(CAGR)は期間を明示すること。「高成長」だけでは判断材料にならない
