This document describes Lean Service Creation (LSC), a methodology that combines design thinking, agile development, and lean startup. LSC helps companies build a culture of experimentation, failure, and learning to develop digital services. It involves conducting user research, rapid prototyping, and analytics testing to iteratively build minimum viable products. The document outlines LSC's process, from immersion and insights to prototyping and growth hacking. It provides examples of tools used in LSC like service blueprints and value proposition prototypes. The result is that companies see real changes to their language, culture, and product development as learning is prioritized over single solutions.
