Qualitative and quantitative methods both have their place in user research, but they address different issues in the UX design process. Understand the differences to pick the right method to learn what you need.
To get useful and valid results from a usability study requires a skilled facilitator who avoids biasing the test while ensuring that the users are comfortable. And who can interpret the participants' actions and statements correctly.
To learn something useful from a usability study, you must have the test participants perform tasks that are representative of typical user goals, while avoiding bias caused by giving too detailed directions or hints.
There are two ways to structure a UX research study when we're testing two (or more) designs: we can have each design tested by different people, or we can reuse the same users for all conditions. Each approach has some advantages and problems.
The 6 steps for running unmoderated usability testing are: define study goals, select testing software, write task descriptions, pilot the test, recruit participants, and analyze the results.
For 30 years, the recommendations have remained the same for improving usability in a UX design project on a tight budget: simplified user testing with 5 users, early test of paper prototypes, and heuristic evaluation.
How to conduct user research for systems with confidential or otherwise sensitive data, for example in domains like healthcare or financial services, where it can be problematic to record screens or otherwise share the user's information.
Even if your target demographics are very broad, you should still identify specific groups of users within that audience to use for UX research and design.
Keeping quiet is a powerful moderation technique for user interviews, usability testing, and workshop facilitation. Well-timed, deliberate periods of silence elicit thoughtful, accurate responses and insights, and build trust with participants.
To guarantee an effective study with users under 18-years old, recruit extra participants, design a child-friendly lab, prepare a plethora of age-appropriate tasks, and avoid being too authoritative.
“That’s just one person” and “Our real users aren’t like that” are common objections to findings from qualitative usability testing. Address these concerns proactively to ensure your research is effective.
Usability testing and other UX evaluation methods can be divided into two major categories: formative evaluation and summative evaluation. Both have their place, but at different stages in the design lifecycle, and they have different characteristics, for example in the number of test participants needed for a good study.
Usability testing is similar to how wild animals hunt for food: we're trying to hunt down the design flaws in the user interface and must optimize a series of studies for total gain, rather than spend too much on any one study.
There are a lot of elements involved in a mobile usability test. In this video, we'll walk you through an example test setup, including the necessary equipment, and discuss how to prepare for a test.
The number of test participants for qualitative usability testing that optimizes return-on-investment is determined by 2 parameters: the facilitator's observational skills and the design team's speed when generating the next design iteration.
Visual design details like fonts and colors can have subtle but important effects on the overall user experience. Use research methods that are sensitive to these effects to test your visual design.
