Managing project teams virtually can create difficulties for leaders. Some online projects have a low level of challenge and require less from a leader, while more challenging online projects can require far more. There are several leadership styles, with different benefits, that can be chosen for each context and the difficulties it presents. The leadership style that is most effective for challenging virtual teams was not clear.
This research evaluates the two most popular leadership styles, transformational and transactional, in virtual projects for both a low level of challenge, and a high level of challenge.

The results show that transformational leadership builds trust more effectively when there is a highly challenging team project, and transactional leadership is more effective when the challenge is low. Therefore, the leader should adapt their style depending on how challenging the virtual team project is.
A strength compared to previous research is that the whole model is contrasted in two contexts which is superior statistically to just comparing some isolated variables in two contexts. The model proves the relationship between transformational leadership, transactional leadership, trust in the team, team performance, and job satisfaction. The model also validates the new, clear, definitions for virtual teams with a low or high challenge. (1) A virtual team project with a low level of challenge has high stability, low intention of turnover, strong communication and strong engagement. (2) A virtual team with a high level of challenge is less stable with a higher intention of turnover, weak communication, and weak engagement.
There are several reasons why in challenging times with a high degree of uncertainty, a people focused leadership is more effective at building trust and overcoming the challenges. Motivating and building commitment become more important. The cost-benefit logic of transactional leadership does not encourage workers to go beyond their tasks and find the innovative solutions necessary. Transformational leadership on the other hand inspires workers to overcome new ill-defined challenges and improve themselves. Put simplistically, teams facing challenges and instability need a visionary leader, not an administrator.
