Project success is crucial for businesses, but the impact of virtual teams on it is still not fully understood. The global outbreak of the COVID-19 pandemic in 2020 has led to the widespread adoption of virtual environment solutions to support geographically dispersed project teams. The growth in the use of virtual or hybrid teams in projects is expected to continue, as it presents an irreversible trend. Furthermore, there has been a significant increase in interest in sustainability in project management in recent years, emphasizing the long-term perspective for project success. To address this gap and contribute to the project success theory, a quantitative study was conducted to examine the impact of stakeholder engagement, knowledge management, and sustainable practices in project management on project success in virtual work environments using structural equation modeling. Experienced Portuguese-speaking project management professionals were surveyed. No evidence was found to support the moderating role of virtual teams, concluding that the virtual nature of a team does not diminish stakeholder engagement, knowledge-sharing, or sustainability in project management and its influence on project success. This study provides valuable insights for enhancing project success in virtual work environments, as it is the first of its kind to quantitatively address the sustainable long-term approach of project success in virtual environments.

This research investigated the crucial correlation between stakeholder engagement and knowledge management, and their role in enhancing sustainability in project management, with a specific focus on the virtual environment. With the shift towards virtual solutions due to the COVID-19 pandemic, as well as the rise of remote work, it has become increasingly important to understand how these constructs interact in this new context. Through a web-based survey questionnaire and Structural Equation Modeling analysis, we found that both stakeholder engagement and knowledge management have a significant positive effect on sustainability practices in project management. Even more interestingly, these relationships remain consistent regardless of whether the project is conducted in a virtual or traditional environment. These findings have important implications for organizations across industries, as they can use these insights to improve sustainability practices in project management by focusing on the integration of stakeholder engagement and knowledge management in the virtual or presential environment. This study is the first of its kind to quantitatively investigate this connection, making it a valuable contribution to the field.
