How Informal Can a Formal Usability Study Be?
You're ready to conduct a formal usability study and have some of your customers or potential prospects available to participate in this study (5-6 users is fine, but don't forget the gratuity). These one-on-one sessions start out with a single user interacting with a web site or wire frame completing a set of tasks, and then a moderator asking them follow-up questions regarding the experience. These sessions usually involve a quiet room, a camera and tracking software to watch a user's expressions and their navigational habits. After the study, the data is analyzed and a formal usability report with key findings and recommendations is written.
The goal of any usability test is to figure out what you're doing right, what you're doing wrong, and learn what your users want. So what are you waiting for?
