18F Guide to using lean UX methodology

An interactive guide (and template) on how to plan and structure projects that use experiments to drive toward outcomes, using agile and scrum methodologies.

###What is lean UX?

Lean UX is a collaborative, outcome-focused product development and project management philosophy and process. It builds on agile and lean principles and provides a structured way to build software through quick, iterative experiments — all within a scrum and agile sprint framework. Note: Lean UX can be adapted to other management and development frameworks, such as Kanban, but for this guide we will focus on scrum and agile.

Doing lean UX means fundamentally changing your team’s focus from outputs (for example, features, functionality, colors) to outcomes (the changes in user behavior you want to see).


Our guide is primarily based on our experience practicing lean UX with teams at 18F, but also draws from ideas and materials from Jeff Gothelf and Josh Seiden's book: Lean UX.
