User testing methods

User testing methods utilize UX design to include users in the decision-making process. UX design is developed primarily to allow users to interact with a website or an app on their own terms.

The underlying objective of user testing methods is to better understand and empathize with the key users of digital brands. However, user testing is often overlooked in most organizations. Many important digital products are launched in the market only with the feedback of stakeholders or employees.

Only a small prototype that may be biased significantly impacts the way a larger audience interacts with it. This lack of user experience trial occurs mainly due to the perceived negative ROI of user testing and concern for scope creep.

The ROI on user testing methods

The usability of UX design, the performance, the quality of the user interface (or GUI) and the adaptability of an app or a web design are key factors in enhancing the value of a digital product.

If you watch people struggle with the design of your product, you will realize the importance of user testing. Many organizations don’t get the opportunity to witness users interacting with their products, which results with them assuming that the UX design is market-ready.

The usability is directly proportional to customer loyalty. Studies show that when 10% of the budget is allocated to user testing, usability increases up to 135%. A customer of ours even saw a return of 147% increase in revenue for their client.

Case Studies

Walmart was heavily relying on quantitative data to increase traffic on its website. However, the data received from the quantitative analysis was cold and of little value. Despite many efforts, it was unable to drive conversion rates or traffic to their website.

Hence, the company resorted to redesigning its UX and search engine to gather qualitative customer insights in addition to the quantitative numbers. This redesigned UX to support customer-driven data helped in achieving a more streamlined and data-driven decision-making process in the organization.

Scope creep reluctance

A common concern is that when the project is running on a tight deadline, there is no time left for user testing.

Specifically, the fear of scope creep during project management can be an instant turn-off. A project manager runs the ship based on three components--budget, time, and scope. A slight pull in one of these components will reflect on the other two components of the project.

Most user testing methods can be quick and easy, but a tight deadline can cut down the performance of the designers and the team to conduct a moderated or in-person user test. With remote usability testing, however, UX teams can launch a test in the morning, and be able to analyze results after lunch.

Types of user testing method

There are many types of user testing methods. Depending on your industry, product, and nature of business, you can conduct tests ranging from behavioral / attitudinal to quantitative and qualitative.

Attitudinal / behavioral user testing methods revolve around people’s feedback, their activities, and their interactions with your business.

Quantitative and qualitative methods focus on direct and indirect observations to generate data based on numerical analysis.

The optimum number of participants for user testing

The book, "A Mathematical Model of the Finding of Usability Problems" reveals that there should be a minimum of 5 participants to test usability. Twenty users will yield similarly confident results for quantitative testing.

The key to discerning your number of participants is more about sprint testing iterative designs with batches of testers rather than one large test.

User testing methods help provide valuable insights not only into the product, but also the customer journey, first impressions, and even brand reputation. They help in revealing aspects of the design that a designer may overlook as an entrenched professional.
