SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides you through the defining phase of a product idea, helping to surface assumptions, frame a falsifiable hypothesis, and route to the next step.

Core Features & Use Cases

Assumption Mapping: Lists and ranks every belief the idea depends on.
Falsifiable Hypothesis: Forms a clear hypothesis to test the top assumption.
Cheapest Prototype: Identifies the lowest-effort artifact that tests the top assumption.
Route to Next Step: Determines the right path for the next stage based on the product type and assumptions.

Quick Start

Run the 'define' skill to begin the defining phase for your product idea.

FAQPage Schema

How do I map assumptions for a new product idea?▼

Framing a falsifiable hypothesis involves forming a clear, testable statement around your top-ranked assumption to validate product decisions and determine the most logical next step for testing.

What is the best way to define a greenfield product idea?▼

After assumption mapping, the cheapest prototype is identified as the lowest-effort artifact that directly tests your top-ranked assumption, minimizing upfront investment while validating the core hypothesis.

Do I need user segmentation data to frame a product hypothesis?▼

Yes, user and customer segmentation input is required alongside UX intent, business viability, and technical feasibility to accurately classify your product and frame a meaningful falsifiable hypothesis.

How do I determine the next step after framing a product hypothesis?▼

Determining the next step involves evaluating your product type, mapped assumptions, and framed hypothesis to route the project to the appropriate downstream action for incremental or greenfield ideas.
