Corporate Social Responsibility is a reality for businesses and can be understood through the analysis of organizational actions in three areas, namely: economic, social and environmental. Its operationalization occurs through projects, and cases presented by the literature can greatly contribute to the definition of factors that lead these projects to success. Generally, professionals and entrepreneurs have good qualifications in traditional aspects of project management, but when they need to manage Corporate Social Responsibility projects doubts arise. In this context, the main objective of this study was to analyse the most impactful Critical Success Factors for Corporate Social Responsibility projects, considering Brazilian companies' context, and to propose guidelines to better qualify new professionals and entrepreneurs in the kind of projects mentioned. Thirteen Critical Success Factors were identified in the literature and, through a survey with experienced professionals, it was possible to evidence the six most relevant for Brazilian companies' context: ability to properly define the scope; ability to integrate the CSR project with the company's strategy; ability to identify stakeholders' needs; ability to analyse risks; identify and involve stakeholders outside the organization; and grant financial resources to meet project needs. Using the information provided, three guidelines were proposed to better qualify professionals and entrepreneurs. This is an exploratory study that can contribute to potentialize debates on theme.
