Description

Measuring the User Experience provides the first single source of practical information to enable usability professionals and product developers to effectively measure the usability of any product by choosing the right metric, applying it, and effectively using the information it reveals. 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. This book is recommended for usability professionals, developers, programmers, information architects, interaction designers, market researchers, and students in an HCI or HFE program.

Key Features

• 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

    So practical and helpful

    I m just at Page 27. But I already have learnt so much from the very detailed description of all the metrics and very importantly how to really apply it to my work. I just opened an excel and redo the case study on this book and felt totally absorbing the methodology and analytical skills! Thanks so much Tom and Bill!
