Usability Testing: A Practitioner’s Guide to Evaluating the User Experience

Designing a digital product without watching real people use it is like cooking without tasting the food. Usability Testing: A Practitioner’s Guide to Evaluating the User Experience brings the essential practice of usability testing into focus for anyone building or improving interactive systems. Morten Hertzum draws on years of human-computer interaction research to provide a practical, evidence-based approach to learning from users.

Why Evaluate with Real Users?

Usability testing remains one of the most direct ways to understand how people actually interact with a design. This book explains how to turn observation into insight—helping you identify problems that might otherwise go unnoticed until after launch. Hertzum walks through the reasoning behind test design, the nuances of moderating sessions, and the art of interpreting results without losing sight of real-world constraints.

A Practitioner’s Field Guide

Rather than presenting evaluation as an abstract academic exercise, this guide treats usability testing as a practical craft. You’ll find discussion of core activities such as planning test scenarios, recruiting participants, collecting data, and communicating findings. The emphasis stays on applying methods flexibly, adapting to project needs, and building evaluation into an iterative design process.

Grounded in Research, Written for Practice

As part of the Synthesis Lectures on Human-Centered Informatics series, the book connects practical advice with the broader HCI literature. Hertzum’s perspective reflects both scholarly rigor and real-world pragmatism. The result is a resource that respects the complexity of user behavior while keeping the focus on actionable improvements.

Who Will Benefit

UX researchers, designers, product managers, and software developers will find this guide valuable for strengthening user-centered practices. Students entering the field will gain a solid conceptual foundation, while experienced practitioners can refine their testing approach.
