Facilitate better usability studies with these 3 techniques: Echo, Boomerang, and Columbo. These methods allow you to get clarification from participants with minimal disruption or bias.
Evidence from usability studies can be more convincing than what you say. Even if you can easily determine the difference between good and bad designs, test them anyway.
Writing good tasks for a usability study is an art, not a science, but there are still rules. Examine your tasks for these 10 common task-writing mistakes.
了解如何运行远程审核可用性测试。This second video covers how to actually facilitate the session with the participant and how to end with debrief, incentive, and initial analysis with your team.
In remote usability studies, it's hard to identify test participants who should not be in the study because they don't fit the profile or don't attempt the task seriously. This is even harder in unmoderated studies, but it can (and should) be done.
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.
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.
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.
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.
Exact costs will vary, but an unmoderated 5-participant study may be 20–40% cheaper than a moderated study, and may save around 20 hours of researcher time.
“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.
Evidence from usability studies can be more convincing than what you say. Even if you can easily determine the difference between good and bad designs, test them anyway.
