- Discovery ResearchParth SanganiUse when synthesizing user research, analyzing interview data, conducting discovery sprints, evaluating evidence quality across sources, or building research-backed feature hypotheses

Encodes Minto Pyramid, audience calibration by executive role, decision architecture, and zero-jargon compression. Produces executive-ready documents, not summaries.
- Go To Market StrategyParth SanganiUse when planning a product launch, market entry, or GTM strategy — segment selection, channel strategy, launch sequencing, pricing validation, competitive positioning, or launch readiness assessment. Encodes wedge identification, channel unit economics, launch gating, and failure criteria. Produces a GTM strategy document, not a launch checklist.
- Metric Design ExperimentationParth SanganiUse when designing a metric framework, selecting a North Star metric, building a metric decomposition tree, designing A/B experiments, setting up retention cohort analysis, or diagnosing whether a metric is being gamed. Encodes NSM rubrics, Goodhart's Law countermeasures, statistical validity for PMs, and retention curve methodology.

Encodes Narrative Arc Construction, April Dunford-inspired Positioning, Why Now analysis, Audience Adaptation, Evidence-Narrative Integration, Objection Anticipation, Competitive Narrative Analysis, and…
- Pricing PackagingParth SanganiUse when designing pricing strategy, packaging tiers, monetization models, or evaluating pricing changes — pricing model selection, willingness-to-pay analysis, competitive pricing maps, package architecture, freemium conversion, usage-based pricing design, or price change impact assessment.
- Problem FramingParth SanganiUse when decomposing a vague problem into a structured problem statement, identifying who has the problem and why it matters, sizing the opportunity, mapping constraints, prioritizing across multiple problems, or producing a Problem Definition Document that feeds into Discovery, Competitive Analysis, or Spec Writing.
- Product StrategyParth SanganiUse when building product strategy, roadmaps, or strategic plans — vision articulation, strategic bet definition, roadmap sequencing, resource allocation, portfolio planning, or quarterly/annual planning. Encodes bet-sizing, option-value sequencing, strategic tension surfacing, and explicit deprioritization. Produces a strategy document, not a feature backlog.
- Specification WritingParth SanganiUse when writing a product spec, feature spec, API contract, agent task spec, or any other specification where a zero-question document is required. Encodes outcome-first methodology, acceptance criteria taxonomy, scope boundary protocol, executor context model, and ambiguity resolution framework.
- Stakeholder AlignmentParth SanganiUse when navigating organizational alignment — stakeholder mapping, influence analysis, coalition building, decision archaeology, cross-functional alignment, executive buy-in, or any situation where the path to a decision runs through multiple people with different interests. Produces a stakeholder alignment strategy, not a RACI matrix.
