Mohan studied 36 projects in Australia and looked into successful IT project management leadership styles. His results indicate that a combination of transformational and technical leadership behaviours augment the effectiveness of transactional leadership leading to high project success. Unfortunately Mohan also found that there is no one leadership style that is effective in all project situations. Therefore he recommends an underlying yet flexible style characterised by organisational catalyst, intellectual stimulation, behavioural charisma, and contingent reward behaviours for enhanced leadership effectiveness.
