A questionnaire was prepared and sent to 5 experts of this field (experienced HR managers) and 3 academicians, for their suggestions and approval. After their review, suggestions were incorporated and final questionnaire was designed that contained 45 items. This questionnaire was then administered to collect the data for the study. The scale used in questionnaire was a 5-point Likert scale ranging from 1 to 5, where 1 represented “Very low importance / criticality”, followed by 2 (Low); 3 (Moderate); 4 (High) and 5 represented “Very High”.
