How can the product be accessed?

When a production version is to be tested, one should ask whether it is readily available via a browser or in an app store (and which app stores, in which countries). The UX researcher will need to know the URLs to use, and whether they differ for mobile and desktop.

When a physical device is being tested, it is important to ask whether the participants are required to own that product in order to qualify for participating in the study, or whether the product will be shipped to each participant.
