A lot of questionnaires look professional on the surface, neatly formatted, properly numbered, printed on good paper, but when it comes time to analyze the data, the questions simply do not connect back to what the study was actually trying to find out. A good questionnaire is designed backward, starting from your research questions, not forward from a template you found online.

Before you write a single question, lay out your research questions or objectives side by side. Every section of your questionnaire should map directly to one of them. If you cannot point to which research question a particular question on your form is meant to answer, that question probably does not belong there, no matter how relevant it feels.
Most solid questionnaires open with a short section on respondent demographics, gender, age range, education level, or whatever background information is relevant to your study, followed by separate sections corresponding to each of your research objectives. Label each section clearly, this makes both data entry and your later chapter three explanation of the instrument much easier to write.
Closed ended questions with fixed response options, like Likert scale statements ranging from strongly disagree to strongly agree, are the easiest to analyze statistically and are the standard choice for most quantitative projects. Open ended questions can add useful context but are harder to analyze at scale, use them sparingly, and only when a fixed set of options genuinely cannot capture what you need to know.
Avoid double barreled questions that actually ask two things at once, like asking whether a service is affordable and reliable in a single statement, since a respondent might agree with one part and disagree with the other, leaving you with a meaningless answer. Also avoid leading questions that hint at the answer you want, a neutral question gets you honest data, a leading one just gets you confirmation of what you already believed.
A questionnaire that takes forty minutes to complete will get rushed, incomplete, or dishonest answers, especially from busy respondents like business owners or working professionals. Cut anything that is interesting but not actually necessary to answer your research questions, a focused fifteen to twenty minute questionnaire almost always produces better quality data than a long, exhausting one.
Run a small pilot test with a handful of people similar to your actual target respondents before you commit to printing or distributing the final version. This often reveals confusing wording, questions that everyone answers the same way and therefore add nothing, or sections that take much longer than expected. Fixing these issues before full data collection saves you from discovering them too late, after your real data is already in.
For validity, have your supervisor or another lecturer in your field review your questionnaire before you distribute it, confirming that it genuinely measures what you intend it to measure. For reliability, especially for scale based questions measuring the same underlying concept, running a Cronbach's Alpha test after your pilot data comes in gives you a proper statistical basis for claiming your instrument produces consistent results, rather than just assuming it.
Writing questions that do not clearly map back to any specific research question
Double barreled or leading questions that produce unreliable answers
Making the questionnaire far too long, leading to rushed or incomplete responses
Skipping a pilot test and only discovering wording problems after full data collection
Claiming validity and reliability without ever actually establishing either
A well designed questionnaire makes every later stage of your project easier, including data entry through to chapter four, because you already know exactly what each question was meant to capture.
