The Elements of User Experience

Jesse James Garrett

jjg@jjg.net

A basic duality: The Web was originally conceived as a hypertextual information space;

but the development of increasingly sophisticated front- and back-end technologies has

fostered its use as a remote software interface. This dual nature has led to much confusion,

as user experience practitioners have attempted to adapt their terminology to cases beyond

the scope of its original application. The goal of this document is to define some of these

terms within their appropriate contexts, and to clarify the underlying relationships among

these various elements.

Abstract

Conception

This picture is incomplete: The model outlined here does not account for secondary considerations (such as those arising during technical or content development)

that may influence decisions during user experience development. Also, this model does not describe a development process, nor does it define roles within a

user experience development team. Rather, it seeks to define the key considerations that go into the development of user experience on the Web today.
