CARBALLO MUNOZ, Lenna  e  BARRIENTOS NUNEZ, Ivette. The causes of the change in software requirements. Rev cuba cienc informat [online]. 2020, vol.14, n.2, pp. 131-144.  Epub 01-Jun-2020. ISSN 2227-1899.

Research shows that one of the main reasons for the failure of a software development project is the change in requirements. The success or failure of these projects depends to a large extent on how they work with the changing requirements. Knowledge of the causes of changing requirements can improve the ability to make better decisions and manage changing requirements effectively. The objective of this research is to present the results of a study that aimed to identify the causes of the changes in the requirements in the software development phases. A bibliographic review was made taking into account the fundamental elements for this. The search produced a large number of articles, but after a careful filtration there were only five articles (six studies) that reported on empirical knowledge of the causes of the change in requirements. Different causes have been identified and their frequency in the software development phases. Although the requirements have been widely cited as one of the main challenges faced by the requirements engineers, it is difficult to find empirical evidence on the causes of the changes. This makes it difficult to generalize the results of the investigation. More empirical research is needed to identify and fully understand the causes of the change in requirements.
