Jtbd growth strategist

JTBD Growth Strategist

Audit your market evidence before deciding to raise prices, differentiate, cut costs, or target a niche.

---

Use this when

• You have quantitative Opportunity Scores ($Opp \ge 10.0$) AND structured market evidence (price willingness-to-pay, unit cost, performance benchmarks, or environmental constraints).
• You want to evaluate whether a proposed strategy (differentiated, dominant, disruptive, discrete, sustaining) has sufficient prerequisite evidence.
• You want to identify disconfirming evidence that contradicts a proposed strategy.

Don't use this when

• You only have qualitative interview notes or complaints without market evidence (use jtbd-context-explorer or jtbd-forces-analyzer).
• You have not yet computed quantitative Opportunity Scores (use jtbd-opportunity-calculator).
• You want to invent pricing or strategy recommendations without data.

Minimum input

• Minimum Input: opportunity_analysis results from jtbd-opportunity-calculator, target segment_definition, and structured market evidence (price_evidence, cost_evidence, performance_evidence, constraint_evidence). If required evidence is missing, returns status: insufficient_evidence.

What you get

1. Decision Readiness Summary: Decision under review, present evidence, missing evidence, what cannot be decided yet, and the smallest next research step.
2. Strategy Assessment Status: evidence_aligned (all prerequisites met), hypothesis_only ($N < 100$), or insufficient_evidence (missing evidence).
3. Excluded Strategies: Explicit reasons and contradicting evidence for excluded strategies.

Quick prompt

"Audit market evidence and evaluate candidate growth strategies for this opportunity dataset: '[Paste opportunity results and market evidence]'."

What to do next

• Status is insufficient_evidence? Use decision_readiness.smallest_next_research_step to gather missing price WTP, cost-to-serve, or performance benchmark evidence via jtbd-switch-interview or user surveys.

Strategy Matrix Prerequisites

Performance / Price / Cost Strategies

Strategy	Minimum Evidence Prerequisites
differentiated	Underserved outcomes ($Opp \ge 12.0$) AND structured price_evidence showing willingness to pay a premium AND structured performance_evidence showing superior capability.
dominant	Underserved outcomes ($Opp \ge 10.0$) AND structured performance_evidence showing superior performance AND cost_evidence showing lower or parity cost-to-serve.
disruptive	Overserved outcomes ($Opp < 8.0$) OR non-consumption evidence AND structured cost_evidence supporting low-cost position and sufficient performance.
sustaining	Appropriately served outcomes ($8.0 \le Opp < 10.0$) in core market; requires parity price and cost structure for incremental performance.

Context-Specific Strategy

Strategy	Minimum Evidence Prerequisites
discrete	1. Environmental, regulatory, security, geographic, or workflow constraint.<br>2. Segment outcome priorities demonstrably different from mainstream users.<br>3. Operational evidence supporting solution feasibility under the constraint.

Strategy Assessment Status Discipline

• evidence_aligned:
  • opportunity_analysis.data_quality_status == "complete"
  • opportunity_analysis.calculation_status == "completed"
  • methodological_assessment.sample_size_status == "adequate" ($N \ge 100$)
  • The selected candidate strategy meets EVERY prerequisite specified in its own rule with structured, sourced evidence
  • No unmitigated disconfirming evidence exists
• hypothesis_only:
  • methodological_assessment.sample_size_status == "small" ($N < 100$), OR evidence relies on unverified domain rationale. Candidate strategies are explicitly labeled as hypotheses.
• insufficient_evidence:
  • opportunity_analysis.calculation_status != "completed", OR required evidence for the candidate strategy is missing.
