Effectively measuring the usability of any product requires choosing the right metric, applying it, and effectively using the information it reveals. Measuring the User Experience provides the first single source of practical information to enable usability professionals and product developers to do just that. Authors Tullis and Albert organize dozens of metrics into six categories: performance, issues-based, self-reported, web navigation, derived, and behavioral/physiological. They explore each metric, considering best methods for collecting, analyzing, and presenting the data. They provide step-by-step guidance for measuring the usability of any type of product using any type of technology.

• Presents criteria for selecting the most appropriate metric for every case
• Takes a product and technology neutral approach
• Presents in-depth case studies to show how organizations have successfully used the metrics and the information they revealed

types of issues, and many others, are typically identified as part of an iterative process in which designs are being evaluated and improved throughout the design and development process. This process provides tremendous value to product design and is the cornerstone of the UX profession. Measuring the User Experience. DOI: © 2013 2012 Published by Elsevier Inc.

Furthermore, the percentage of participants who are experiencing these issues is decreasing with each design iteration. Another form of analysis is to aggregate all the high-priority issues to report the percentage of participants who experienced any high-priority issue. This helps you see how overall usability is changing with each design iteration, but it is less helpful in determining whether to address a specific usability problem. 5.4.4 Issues by Category Number of Usability Issues

measurements: how our weight changes when we step on the bathroom scale, where to set our thermostat in the evening, and how to interpret our water bill every month. The user experience field is no different. We have a set of metrics specific to our profession: task success, user satisfaction, and errors, among others. This book gathers all the UX metrics in one place and explains how to use these metrics to provide maximum benefit to you and your organization. So what is a UX metric and how does

your organization and that can’t be answered by other means. For example, UX metrics can answer these critical questions: • • • • • • Will the users recommend the product? Is this new product more efficient to use than the current product? How does the user experience of this product compare to the competition? Do the users feel good about the product or themselves after using it? What are the most significant usability problems with this product? Are improvements being made from one
