Why Usability Testing Is Worth It

In usability testing, we check whether the concept matches reality. Through structured tests with real users, we validate prototypes and processes, identify risks early, and provide evidence for usable solutions.

Replace assumptions with facts

Even the best team can’t think for every user. Tests show where real people behave differently than expected and whether the interaction concept works — in prototypes as well as in existing products. This makes blind spots visible before resources are funneled in the wrong direction.

Increase acceptance and adoption

Prototypes validated by real users build trust. Development teams gain objective decision-making foundations instead of opinions, and investments in UX initiatives are justified by measurable evidence. Tests make design decisions transparent and reduce internal discussions.

Compliance evidence for regulated products

In regulated industries (medical devices, laboratory equipment), user testing is part of the required evidence documentation. It provides objective proof of usability and use-related risks—essential for IEC 62366-1 and usability engineering files.

Identify risks early and reduce costs

Fixing errors in the finished product costs many times more than testing at the prototype stage. User tests uncover critical weaknesses before they become expensive.

Why do we test with real users?

Designers and developers think differently than typical users—real tests reveal stumbling blocks no one can predict. What seems "intuitive" to the team can fail in actual use. Tests surface this early, before changes get truly expensive. They also show which features are actually used and where improvements will have the biggest impact. And: users who are involved are more likely to use the solution later—and become advocates.

Would you like to participate in a test?

We are always looking for more test participants so that we can find the right people for each of our projects. So if you would like to take part in a real usability test, whether here in Jena or online, please get in touch with us! Since not every tester matches the target group for a project, only those who are truly suitable will be contacted — so you don’t have to worry about spam!

Usability testing methods

Usability tests help evaluate how real users interact with a product or user interface by combining quantitative and qualitative approaches. Together, these approaches provide a comprehensive understanding of the user experience.

Quantitative usability tests focus on collecting measurable data to identify patterns, effectiveness, and efficiency in user behavior. They provide insights based on numbers and support data-driven design decisions.

Qualitative usability tests, on the other hand, examine the reasons behind user actions by observing thoughts, motivations, and feedback. They uncover deeper usability issues that might otherwise be overlooked based on metrics alone and add the corresponding context to the numbers.

Test events

At our usability test events, we invite customers and test participants to try out products, software—basically anything—in a relaxed atmosphere. It’s an entertaining, hands-on way to gather feedback while enjoying pizza, beer, and good conversation.

FAQ

When is the right time for a user test?

How many users do we need for a test?

What is iterative design?

Can we test with our own team?

Nothing is ever final

Iteration brings clarity. We improve the design in cycles—and create the foundation for a smooth handoff to implementation.
