Effective leaders are able to function in a mentoring role and exhibit empathy towards their team members. These leaders are able to exert their authority without appearing overbearing or inflexible (Kayworth and Liedner, 2002).A positive correlation has been found to exist between transformational leadership and the performance of the organization (Lowe et al, 1996). Transformational leaders are very effective within an organizational context because they are able to inspire their followers, provide support, mentoring and coaching for their followers and infuse them with their own enthusiasm and energy. The transactional leadership style is a more practical kind of leadership pattern and a good transactional leader recognizes the qualities in his followers and makes rewards contingent upon good performance, thereby also contributing to organizational efficacy. (Pillai et al, 1999). Within an organization that focuses on creativity and innovation, the transformational style may be effective, while a transactional style of leadership may be more appropriate for larger organizations where people do not work together in small close-knit groups.The lack of good leadership communication skills or a failure of the leader to interact well with team members in order to provide a supportive working environment provides a badly managed business where organizational effectiveness is hindered. The wrong kind of leadership style may also impact unfavorably upon an organization and impede its effectiveness. In the context of an increasingly global environment where most organizations are subjected to intense competition, existing leadership styles may need revamping to be effective. This quantitative study, therefore, proposes to use a survey method in order to examine these two aspects of leadership in the context of organizational effectiveness. In the case of the first question, the null hypothesis which is proposed is: There is no relation between leadership skill development, leader behavior, supervision, and coordination on the team communication effectiveness.
