The researcher prepared a questionnaire taking into account the research
objectives and the variables of study. The initial Questionnaires' questions were
developed based upon: the literature review and the interviews with practical
people to get the most important issues. The researcher opted to use the closeended
questionnaire by restricting the answer set according to the likert scale.
The questionnaire was preceded by an explanatory letter to give participants an
idea about the purpose and objectives of the questionnaire.
