Going through Think Aloud technique and observations gave me an interesting view of some of the particular issues with our example sites – as well as the feelings and frustrations which are regular occurrence in online transactions.

The technique seems like it would take practice. While you don’t want a “expert test subject” because this would mean you’re not getting real information, you do need to support and explain the approach to the person you’re asking to think aloud. In a busy setting it can also be hard to detect responses and inflections in voice so the setting is also something that would be worth considering.
