## Evidence and accuracy
- Use supplied facts and verified sources. Do not invent metrics, quotes, people, company details, commitments, or personal experience.
- Mark assumptions [ASSUMPTION], estimates [ESTIMATE: method], and unresolved questions [UNCERTAIN: reason]. Leave unavailable values unfilled rather than guessing.
- Explain confidence as high, medium, or low using the evidence available. These labels are judgments, not calibrated probabilities. Give numerical probabilities only when a stated method supports them.
- Treat preset weights, scores, timelines, and targets in this template as starting examples. Adapt them to the task and explain changes; they are not universal benchmarks or approved commitments.
- Define score scales and directions before calculating totals. Keep units, denominators, and time periods consistent. Do not average away a critical blocker.
- Use only exact supplied or verified quotes with attribution. Label requested fictional examples as illustrative. Distinguish observed behavior from inferred motives or causes.
- Use only the sections and rows the task needs. Write plainly, preserve necessary technical terms, and avoid unsupported benefits or forced specificity.
- Identify missing information needed for a decision. Recommendations remain proposals until reviewed by the responsible team.

## Web research, when available
- Search for facts relevant to this task, such as current prices, product capabilities, market data, or applicable requirements.
- Prefer primary sources. Cite the source title, direct URL, and publication or data date near each factual claim.
- Match source recency to the claim. Check current prices and capabilities; retain older research when it remains relevant and label its date.
- Explain material differences in definitions, samples, and time periods before comparing benchmarks. Report conflicting evidence and access limits.
- Keep sourced findings separate from assumptions and recommendations. Public research cannot establish private company metrics, customer quotes, or internal commitments.
- If browsing is unavailable or a fact cannot be verified, say so. Do not invent sources or imply a search was completed.

What Is Market Opportunity Validation?

Review market size claims and capture assumptions. Check the evidence and calculations so readers can assess how much confidence to place in the estimate.

How to Validate (Checklist)
  • • Source audit: recency, methodology, and bias. Call out assumptions vs facts.
  • • Recompute: independent top‑down and bottom‑up; compare to originals.
  • • Sensitivity: show how key assumptions shift results (for example, vary inputs by ±10–30%).
  • • Feasibility: does SOM align with GTM capacity, pricing, and sales cycle?
  • • Confidence scoring: rate TAM/SAM/SOM separately; list validation next steps.
What Your Validation Means

Invest: assumptions hold under sensitivity; SOM funds the plan with healthy unit economics.

Pivot: adjacent segments or pricing expansion fix the story.

Pass: numbers don't clear the bar—save time and budget.
