Elizabeth Snowdon is a senior usability analyst at Sage Software who has been conducting usability studies since 2003. She discusses remote usability testing, which involves testing sessions where the participant and moderator are not physically in the same place but communicate electronically. Some advantages of remote testing are that it expands recruitment populations, saves costs compared to in-person lab testing, and allows testing in users' natural environments. However, remote testing has disadvantages like not being able to see participants' screens and potential technical issues. Snowdon provides an example case study where remote testing saved $50,000 compared to in-lab testing.
