An interview is an intentional interaction between persons in which one person seeks information from another person. Interviews can take place face-to-face or by other modes of personal interaction (York, 1998). As mentioned previously forty face-to-face interviews and ten phone interviews were conducted. Usually when I needed to obtain information from managers, supervisor and people whom I do not know very well I used to do Face-to-face interviews. As well as there sometimes could be non-common question, that you can not ask everyone. The fact that I would be on the opposite rotation (field employee) with others colleagues I used to call them and carry on the interview via the phone. I did interviews, because some of my friends, relatives and family do not speak or read English. English and Arabic questionnaire were used due to the reasons presented earlier. Close-ended questions were used as this provided cooperation and more likely to get responses rather then the open-ended structures. Even though answer choices were made available, respondent had the option of offering their own responses at the end of the questionnaire as there were some of the open-ended questions.
