Objective of the study: To understand how project management contributed to the implementation and integration of two ERP systems, in order to improve the standardization of Knowledge Management of these companies. Methodology / approach: The approach used for the study will be qualitative in nature and, as a method, a field research will be applied using semi-structured interviews. Secondary data will also be collected from companies, such as documents that were part of the implementation process and also the theoretical framework that will support the analysis. Thus, it will be possible to perform the triangulation of the data. The data, after being collected, will be analyzed with the aid of MAXQDA software. Originality / Relevance: The study is justified by presenting a practical application of project management in the implementation of ERP software in two different companies and an empirical confirmation of the relationship between the themes. Key Findings: Demonstrate that professional, non-intuitive project management collaborates with good project progress. On the contrary, used without methodological rigor causes disorder in the project. And that the implementation of the ERP system for knowledge management, corroborating the literature, really implies a better strategy providing competitive advantage for the company. Theoretical / methodological contributions: The study contributes to the relationship between knowledge management and project management of ERP software implementation projects that were empirically tested, meeting the authors approached. Social Contributions to Management: Contributes as a best practice guide for knowledge management project managers.
