Development of a valid and reliable software customization model for SaaS quality through iterative method: perspectives from academia

Despite the benefits of standardization, the customization of Software as a Service (SaaS) application is also essential because of the many unique requirements of customers. This study, therefore, focuses on the development of a valid and reliable software customization model for SaaS quality that...
