Diseña experimentos para probar suposiciones de un producto existente — prototipos, pruebas A/B, spikes y otros métodos de validación de bajo esfuerzo. Se usa para validar suposiciones, probar ideas de funciones de forma económica o planificar experimentos de producto.
Este skill permite diseñar experimentos estructurados de bajo esfuerzo para validar suposiciones sobre un producto existente. Es especialmente útil para equipos de producto, startups o desarrolladores que necesitan probar hipótesis rápidamente sin invertir grandes recursos. El skill guía la creación de prototipos, pruebas A/B, spikes técnicos, entrevistas de validación y otros métodos de experimentación lean. Al usarlo, se definen claramente las suposiciones clave, se selecciona el método más adecuado según el contexto (ej: incertidumbre técnica vs. de mercado) y se planifica la medición de resultados. Está diseñado para integrarse con flujos de trabajo ágiles y herramientas de gestión de producto como Jira, Trello o Notion, facilitando la documentación y el seguimiento de experimentos. Su enfoque está en minimizar el tiempo y costo de validación, permitiendo iterar rápido y tomar decisiones basadas en datos.
