Abstract

Non-functional requirements (NFR) need to be known and properly treated since the beginning of the software development cycle. This study aims to investigate whether the NFR of the application can be obtained from the customers, according to the opinion of the professionals involved with the software development process. For this, a research process based on the model provided by Kitchenham and Pfleeger was used. 98 (ninety eight) professionals with different levels of experience participated of the research. Results showed that professionals believe that most NFR types can not be requested by the application customers because of lack of technical knowledge.
