Software development organizations continuously seek to increase the productivity of their teams. However, productivity in the development of a software product is characterized by a high dependence on social and human factors. Therefore, studying these factors is essential to meet the performance needs of software development organizations. The above supports the motivation to consider the social and human factors that may influence the productivity of software development teams. This research has been conducted to classify such factors associated with the productivity of software development teams. For this purpose, a methodology was designed based on systematic literature review processes and evaluation processes with a psychology expert. The classification of social and human factors and their respective definitions are the partial results of this investigation. The proposed classification is an essential input for the establishment of improvement actions.
