The research population contains 15 experts in library software designing team including ‘an operator’, ‘a system analyst’, ‘a supporter’ and ‘a graphic artist’ that have rich and extensive knowledge of the field. The sampling method is snowball sampling and respondent-driven sampling. In terms of methodology, the present study fall into the category of qualitative research.
