Given the importance of this issue, the aim of this study is to investigate the concept of Applicability, its relationship with users and ways to improve it. Information sources or data: This review study was conducted using the Thematic search on the online databases such as PubMed, ProQuest, Google Scholar, Science Direct, Scopus and professional web sites and books. Selection methods for study: Articles and content were selected based on the similarity of content and their adaptation to the study objectives that were fifty full text articles, 12 books and 6 scientific materials. These materials were studied in detail and 38 of them were used to compile the final version of the study. Combine content and results: ISO defines usability as an extension a product can be used by specific users to achieve goals with efficiency, effectiveness, and satisfaction in a specific context.
