Lean UX

Applying Lean Principles to Improve User Experience

Design as a fast, collaborative, hypothesis-driven team activity.

by Jeff Gothelf with Josh Seiden

Lean UX applies the principles of Lean Startup and agile to the practice of user experience design. It reframes design as a collaborative, hypothesis-driven process focused on outcomes rather than polished deliverables. The book shows teams how to test assumptions quickly through experiments and continuous learning.

Founders need design to move at startup speed, and this book shows how to integrate UX into rapid build-measure-learn cycles. It replaces heavy documentation with shared understanding and quick experiments. The hypothesis framing keeps small teams focused on validating real outcomes.
