lean-startup

Tests a venture under uncertainty using the Lean Startup method (Eric Ries, The Lean Startup): treat the idea as untested hypotheses, run the smallest experiment on the riskiest one, measure real behavior, and decide pivot or persevere. Catches the failure of mistaking features shipped and motion for progress when neither has validated anything about customers.

The core concepts (leap-of-faith assumptions, Build-Measure-Learn, MVP, actionable versus vanity metrics, pivot or persevere) live in references/lean-startup.md. Load that file before facilitating.

When to use

The user has a product or business idea facing real uncertainty about whether customers want it or whether it will grow, and wants to test it cheaply before committing. For designing the solution itself around user needs, Design Thinking fits upstream; this skill is about validating that the thing should exist and will work.

Language

Facilitate and write the document in the language the user is writing in. The reference file is English; keep the framework keyed to it regardless of output language.

Inputs

• IDEA (required): the product or business idea, and who it is for.
• CONTEXT (optional): stage, resources, what has been built or tried, and any evidence so far.
