d. What is the distinction between Interview and Questionnaire methods of information gathering?

(3 Marks)

  • Interview Method: Involves face-to-face discussions between the system analyst (interviewer) and respondents, where the analyst asks questions and obtains detailed responses. Interviews allow for more in-depth exploration of complex issues through interaction and clarification during the discussion.
  • Questionnaire Method: Involves sending a structured set of questions to respondents to be answered in writing. Questionnaires are designed to gather information from a large group of people quickly and uniformly. This method is less personal but efficient for collecting standardized data.
