Research Paper (postgraduate) from the year 2021 in the subject Business economics - Business Management, Corporate Governance, grade: 1,7, Johannes Gutenberg University Mainz, language: English, abstract: Globalization, the resulting environmental changes, and the ongoing decentralization of the work process, as well as constantly evolving technologies and the current global pandemic, have significantly driven the formation of virtual teams (VT). Members of VT are geographically separated from each other and communicate via computer-mediated communication. The rapid implementation of digital technologies, especially virtual team collaboration technologies, leads to an increasing number and relevance of VT which is also evidenced by the fact that nowadays a large part of professionals already work or have worked in VT. This seminar paper is based on the following research question: Could transformational leadership influence the relationship between virtuality and team effectiveness? The objective of this paper is to give a brief overview of the existing research results on the individual variables, virtuality, team effectiveness, and transformational leadership style, as well as examining the main effect of the influence of virtuality on team performance and investigate the moderating variable in terms of whether transformational leadership can lead to improved team effectiveness in a virtual context.
