Virtual teams are gaining importance because they have given organisations and employees the ability to work from anywhere in the world without relocating them. The ability to work remotely and collaborate virtually has allowed organisations to expand their reach and tap into a global talent pool. Additionally, COVID-19 has resulted in seeking alternative work arrangements, including the information technology (IT) industry. However, virtual teams also have challenges that can affect team efficiency and effectiveness. Factors such as knowledge sharing, trust, language and cultural differences, distance, and time zone differences can all impact virtual team performance. This research describes several important factors that affect global virtual team efficiency, especially in IT projects, and underlying solutions are addressed to reduce the barriers. By understanding the challenges and implementing effective solutions, organisations can leverage the benefits of virtual teams.
