Iteration
Test, learn and refine
Replace assumptions with facts
Even the best team cannot think for all users. Tests show where real people behave differently than expected and whether the design concept works – in prototypes as well as in existing products. This makes blind spots visible before resources flow in the wrong direction.
Increase acceptance and adoption
Through prototypes validated by real users, development teams receive objective decision-making bases instead of opinions, and investments in UX measures are legitimized by measurable evidence. Tests make design decisions understandable and reduce internal discussions.
Compliance evidence for regulated products
In regulated industries (medical technology, lab equipment), usability tests are part of the required proof obligation. They provide objective evidence for 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 what testing at the prototype stage costs. User tests reveal critical weaknesses before they become expensive.
Context analyses
Method mix - qualitative and quantitative
Quantitative Usability Tests focus on capturing 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, investigate the reasons behind user actions by observing thoughts, motivations, and feedback. They uncover deeper usability issues that may be overlooked based solely on metrics, adding the necessary context to the numbers.

The most important steps of idea generation in the UX process
Idea generation is not just brainstorming – it is a structured part of the UX process, in which ideas are shaped, tested, and refined. It serves as a bridge between research and design, transforming insights into clear, user-centered solutions. Here are the essential steps:
