Research: Usability Testing

Does usability testing work for documents? Our answer is a resounding yes.

In this column, we’ll give you three techniques for having people try out documents or any other stand-alone content. These techniques apply whether your document is on paper or online—for example, as a Web page or a PDF. They apply for both in-person and remote usability testing—especially with moderated remote testing.

What Is a Document?

Functional documents include informative banners—such as the ones on many Web sites about how an organization is dealing with COVID-19—legal documents, manuals, notices, official letters, press releases, privacy policies, terms and conditions, and more.

When I began my career as a UX designer, many product developers shared the aspiration of building great products with numerous features. While building great products is a worthy goal, teams often paid little attention to users’ real needs when deciding what features to build, which is a great shame. App development is not just about creating a product but about solving a problem for users. As an essential part of human-centered design, user research helps us to crystallize users’ problems and create solutions that directly address them.

As a design lead, I make user research an integral part of my team’s design process. We use various approaches to interacting with users to help us tailor the end product to the audience’s needs. In this article, I’ll share some of my experiences conducting different types of user research, focusing mainly on in-depth user interviews, usability testing, and surveys, but we’ve used all of the approaches that Figure 1 depicts. You’ll learn how to use each of these types of user research and discover useful methods of collecting and analyzing users’ thoughts. Read More

UX researchers and other project stakeholders often fervently debate the number of participants that are necessary for usability studies. At the core of this debate is often the tension between the usability professional’s desire for the best possible study and the business team's desire to reduce time and expense.

In 2009, Ritch wrote an article for the Journal of Usability Studies titled “How to Specify the Participant Group Size for Usability Studies: A Practitioner’s Guide” to address this issue. He based his article on a wide survey of the literature then available, and his intent was to help usability professionals make clear recommendations for the size of participant groups in particular contexts, as well as to understand the basis for those recommendations and their associated risks.
