Market and Competition Analysis

Use $ARGUMENTS as initial context.

When to use this skill

• Market entry or expansion decisions.
• Competitive positioning or response planning.
• Product or GTM strategy requiring market evidence.
• Cases where market assumptions must be made explicit and testable.

Required inputs

• Market definition and geographic scope.
• Decision to support and required depth.
• Available internal/external data and timeline.

Workflow

1. Define market boundary, customer segments, and time horizon.
2. Triangulate TAM/SAM/SOM using top-down and bottom-up methods.
3. Build competitor set including substitutes and adjacent threats.
4. Compare value propositions, pricing, channels, and capability signals.
5. Rate uncertainty of assumptions and develop base vs stressed scenarios.
6. Deliver implications, risks, and next analytical moves.

Ask-first questions

Ask up to 3 questions before sizing:

1. Which strategic decision must this analysis support?
2. What market definition is non-negotiable for this decision?
3. Which data sources are considered reliable by stakeholders?

Assumption policy

• Proceed with assumptions when data is incomplete.
• Mark each key assumption with confidence and sensitivity.
• Separate observed facts from inferred estimates.

Output contract

Always produce these sections in order:

1. Context
2. Decision or Recommendation
3. Analysis
4. Risks
5. Next Actions
6. Assumptions

Guardrails

• Do not present single-point market size without method disclosure.
• Include at least one substitute threat in competitor mapping.
• Distinguish strategic implication from raw market observation.
• Flag scenario sensitivity when assumptions materially shift conclusion.
