Development of Quality Performance of National Digital Library with Kano's Model Approach

Background and Aim: The purpose of this study is to determine the quality requirements of the National Digital Library based on the Kano model and categorize users needs into three groups of:  Basic, functional and motivational. Methods: This survey was conducted with a qualitative approach. The requirements of the digital library were extracted using two standards: "Digiqual manual" and the "Digital Library Evaluation Manual."   The requirements were adjusted based on Kano model in a questionnaire consisting of four categories and 52 pairs of questions (104 questions). Results: The results of each of the requirements (basic, functional, motivational) in four dimensions (access control, content, data retrieval, and visual effects) show that   half of the userschr('39') requests are in the basic requirements group which National Digital Library officials should pay more attention to and prioritize the redesign or development plan of the digital library. Also, the second priority was the requirements of the functional group. Paying attention to the requirements of this group causes satisfaction and dissatisfaction otherwise. Attention to meeting the motivational requirements of the third priority if met  could create a high level of satisfaction in the use of the National Digital Library. Conclusion: If clienteles  satisfaction is of worth,    managers of the National Digital Library should design short-term and long-term programs according to the users real needs.
