Hypothesis Driven 80/20
Use $ARGUMENTS as initial context.
When to use this skill
- Ambiguous problems that need fast direction before full analysis.
- Prioritizing limited team capacity across competing hypotheses.
- Designing a test plan with clear stop or continue criteria.
- Converting broad strategic questions into measurable experiments.
When not to use this skill
- Do not use it to create a broad issue tree, a market inventory, or a portfolio allocation without a testable decision question.
- Do not label opinions as hypotheses when no measurable disconfirming signal is possible.
Required inputs
- Governing business question and target metric.
- Time horizon and decision deadline.
- Data constraints and available analysis bandwidth.
- Current baseline, unit of analysis, and minimum reliable signal.
Workflow
- Define one decision question and explicit success metric.
- Generate 3-7 falsifiable hypotheses using strict format.
- For each hypothesis define expected signal, disconfirming signal, kill threshold, and measurement window.
- Score hypotheses with 80/20 lens: impact, confidence, effort, speed.
- Select top 1-2 hypotheses for minimum viable tests.
- Build workplan with owners, deadlines, and decision checkpoints.
Ask-first questions
Ask up to 3 questions before ranking hypotheses:
- Which single metric determines decision success?
- What is the latest acceptable date for a go or no-go decision?
- Which datasets are trusted and immediately accessible?
Assumption policy
- If critical data is unavailable, proceed with transparent assumptions.
- Annotate each assumption with confidence and validation action.
- Avoid merged hypotheses; keep one causal chain per hypothesis.
- Record data quality, sample limitations, and the test's decision relevance.
Output contract
Always produce these sections in order:
- Context
- Decision or Recommendation
- Analysis
- Risks
- Next Actions
- Assumptions
- Every test includes an owner, due date, success signal, and decision checkpoint.
- Label evidence as Fact, Inference, Assumption, or Unknown.
Guardrails
- Hypotheses must follow: "If X, then Y, because Z.".
- Avoid descriptive statements that cannot be disproven.
- Include both confirming and disconfirming signals.
- Stop low-value analysis once kill threshold is reached.
- Do not use false precision when the data cannot support a numeric threshold.
Handoffs
- Use
consulting-issue-tree-mece when the causal structure is still unclear.
- Use
decision-analysis-under-uncertainty when several tested options must be compared.
- Use
execution-operating-system when experiments become a sustained delivery program.
