A questionnaire can collect a great deal of information and still leave the main business question unanswered. The starting point should be the decision the research is intended to support.
Begin with the decision
A brief such as “understand our customers” is a useful starting conversation, but it needs refinement. Is the organisation deciding whether to change a service, enter a market, introduce a product, or prioritise a customer segment? Each decision calls for different evidence.
Write the decision in plain language. Then identify what is already known, what remains uncertain, and which information could change the choice.
Translate objectives into questions
Each part of the questionnaire should serve an objective. Questions about behaviour, experience, preferences, and barriers should connect to the planned analysis.
A question may be interesting without being useful to the decision. Removing unnecessary questions can reduce interview burden and make room for the details that matter.
Define the audience carefully
The audience should have relevant experience. For example, a study of supplier selection needs people involved in selecting suppliers, rather than everyone employed in the target industry.
Eligibility criteria should distinguish essential experience from desirable characteristics. This helps keep the recruitment plan aligned with the research question.
Plan the output before fieldwork
Agree how the results will be compared and reported. If the decision depends on differences between business sizes or customer groups, the study needs suitable recruitment and an analysis plan for those comparisons.
The final report should explain the findings, the limits of the evidence, and the implications for the decision.
Closing
A clear objective gives the study direction. It helps the questionnaire, recruitment, and reporting work toward the same purpose.
