Usability inspection is a form of usability evaluation. It is based on the judgment of one or more evaluators who examine or use an interactive system to identify potential usability problems, and deviations from established dialogue principles, heuristics, user interface guidelines and user requirements. The evaluators base their evaluation on their experience as user experience professionals or as users of the interactive system that is being evaluated.

A heuristic evaluation is a specific form of a usability inspection that is guided by a list of approximately 10 heuristics.

User surveys evaluate users' satisfaction with an interactive system. In a user survey, users report subjective data into a questionnaire based on their experience of using an interactive system. The usability of a questionnaire is important; for example, the questions in the questionnaire must be easy to understand and the questionnaire must keep users informed of their progress.

User surveys are also used to gather context of use information as part of understanding the context of use.

Interviews should focus on gathering information about the current context of use rather than the interactive system itself. They should be done contextually. A contextual interview takes place at the location where the user's interaction with the interactive system usually takes place, for example the user's workplace, their home or in a shop. An ordinary interview takes place in a neutral environment, for example in a meeting room.

During a contextual interview, the interviewer treats the interviewee as the master while the interviewer is the humble apprentice (master-apprentice model). The interviewer asks because they sincerely want to learn -not because they want to demonstrate their knowledge. The interviewer should use open and neutral interview questions rather than closed and leading questions to avoid biasing the interviewee.

The interviewer should rely on an interview checklist to ensure that all relevant topics are addressed, rather than using it to control or steer the interview.

The outcome of this activity is a description of the context of use. The context of use has five components: Users (people who interact with the interactive system), Goals (what users want to achieve), Tasks (what users do to achieve their goals), Environment (where the interaction takes place), and Resources (the means required to perform the task).
