Usability testing is hard. Success depends on so many variables and getting any of them wrong will leave you with tainted results. What tasks you prepare, when to stay silent or how to interpret hesitation - just a few examples how slipper this field is.
To understand what to watch out for, I talked to Zsombor Varnagy-Toth, Senior UX researcher @ SAP Emarsys who has recently released a book about common pitfalls in usability testing. Zsombor is a cognitive psychologist with over 10 years of UX research experience and has run countless number of usability tests throughout his career.
Zsombor shared a number of practical tips that help you learn more from usability tests. Best thing, you can try them easily in your next usability test.
Zsombor has been a UX researcher at SAP Emarsys for +7 years. He also draws on r+5 years of experience from academia where he worked a research assistant after graduating in cognitive psychology. In January 2024, he published his first book called "A knack for usability testing".
