Overview of the Impact of Project Portfolio Management on Firms Performance

The objective of this paper is to explore and analyze previous research about the relationship between project portfolio management success and business performance. In order to analyze this relationship, a systematic literature review was performed on scientific databases related to the area of management using inclusion and exclusion criteria defined according to the objective of this literature review. The study found 940 articles and after a comprehensive review 66 were selected. From these articles, we can observe that the relationship of portfolio management and firm performance, although several researchers from different perspectives have covered it, still presents many fields of research. Most of the previous research is based on case studies in medium sized enterprises stating the need for quantitative research that allows to generalize results and also research of the impact of project portfolio management in SMEs.
