These three objectives are generated, after the researcher critically reviews the book, articles and journal. Three objectives might apply in interview through face to face interview to local construction site personnel.
3.4 Rationale of Questionnaire Design
This dissertation title is â€œSafety Plan in Construction Site: Safety Officer Perspectiveâ€Â. Safety and Health Officer is playing a very important in create a safe workplace.

Quality of data collected
The problem might encountered during the interview are the quality of information and data that collected from the different interviewees. All interviewees are from different background, furthermore they have different experience and opinion in safety and health issues, so the data that obtained by them may vary. To over come this problem, interviewer might select the interviewees who have number of years experience in construction firm. Beside that, interviewer may interview the site personnel who currently on position project manager or site supervisor or safety and health officer.
Low respond rate
During the interview, the interviewer may encountered hard to make appointment with the interviewees, because not many people are willing to interview. In interviewees opinion, interview are not part of job for them, the interviewees might think spend time to accept interview and answer the questionnaire is wasting time.
