Questionnaires

Structured written question sets used to quickly gather information from a large number of people.

Key Points

  • Efficient for collecting input from many stakeholders in a short time.
  • Can include closed-ended and open-ended questions for quantitative and qualitative data.
  • Often administered online or on paper, enabling broad reach and anonymity.
  • Less depth than interviews or workshops, so questions must be clear and unbiased.

Example

A project manager sends an online questionnaire to 250 users to rank feature priorities and report pain points, enabling rapid analysis and requirement prioritization.
