Definition Workflow Lean Startup

lean-startup

Eric Ries' Lean Startup methodology. Build-Measure-Learn cycles with validated learning, MVP focus, and pivot-or-persevere decisions.

Inspired by Lean Startup. The methodology is its originators’ own published work, drawn from their public writing and talks. ProductBuildersHQ has implemented it as a machine-readable workflow in VisionSpec so it can be automated — spec synthesis and LLM-as-a-Judge evaluation, built in. This encoding is an independent interpretation, not affiliated with or endorsed by its originators.
