Guidelines

• Base the questions on the usability test objectives.
• Questions should be simple, understandable, concise, precise, relevant, and to the point.
• Questions should not require a long response from the test participants. Where practical, use multiple choice questions instead of essay questions that require the test participant to write free-form responses.
• Ask numerical questions in terms of ranges because poeple are often reluctant to provide exact personal details, such as age or salary.
• Internally test and revise the questionnaire before using it in actual practice.
• Questions should be appropriate for all test participants.
• Questions should concentrate on obtaining subjective information that cannot directly be observed such as the test participants' observations, opinions, preferences, and recommendations. The test monitor and recording equipment are responsible for documenting the test participant's objective observable behavior.
