Gathering feedback from drivers and passengers is an important step in any project, and there are many methods to choose from, depending on your goal, budget, and timeline. Surveys and questionnaires are useful for collecting quantitative data, such as ratings, preferences, and satisfaction levels. Interviews and focus groups can be used to collect qualitative data, such as opinions, insights, and suggestions. Observations and tests are also great for collecting direct and objective data, such as behaviors, reactions, and performance. When creating surveys or conducting interviews or tests, make sure your questions are clear, concise, and relevant. Prepare a script or a guide with open-ended questions for interviews or focus groups. Have a clear protocol and criteria for observations or tests. Record or document your results for all methods.
