Background Projects enable the resolution of problems and alter societal realities, assuming they represent the optimal choices to modify living conditions positively. If projects are deemed intelligent solutions to problems, why do they fail? This question will be addressed in this article through bibliometric analysis. Methods A bibliometric analysis was conducted on the success or failure factors influencing social investment projects, through a descriptive study with search equations, utilizing a comparative matrix to analyze 32 articles from Scopus and 22 from Web of Science. Results As a result, the number of publications, the themes addressed, and their origins between 2018 and 2023 were identified. The VOSviewer software allowed for identifying keywords and their relationships; with this input, a review of scientific production was conducted to subsequently identify the factors influencing projects and how they have been addressed within their contexts. Conclusions In conclusion, it was found that both the factors influencing success or failure in projects are permeated by the environment and the impact of political, social, and economic factors, in addition to the interaction of elements related to soft and hard skills.
