Abstract
The concept of project success in today’s project management is the core concern due to
increased project failures. So many studies have been done in this area because several
factors contributed to the projects’ success. The leadership skills of project managers are
one of the critical factors contributing to the success of projects. The purpose of this study
is to examine the moderating role of top management support in the relationship between
project managers' leadership styles and project success on mega projects undertaken by the
Addis Ababa City Government Mega Projects Construction Office. The study adopted a
cross-sectional survey of descriptive and explanatory design with a quantitative approach
to test the study hypothesis. Data were collected from the total population of the study area
because it was small and accessible. Eleven (11) projects were selected for the study sample,
all the projects currently run under the authority of the Addis Ababa City Government Mega
Projects Construction Office. One (1) project manager and 3 (three) key respondents from
each project were selected for the questionnaire. Among the total forty-four (44) distributed
questionnaires only 36 were responded to and used for analysis. The result of the study
shows that transformational and democratic leadership have a statistically significant
positive relationship with project success. However, no statistically significant relationship
between transactional, laissez-faire, and authoritarian leadership and project success. This
implies that contractors and project owners should emphasize the leadership style of the
project managers before assigning them to lead projects. In addition, top management
support strengthens the relationship between project success and transformational,
transactional, and democratic leadership. Nonetheless, top management support did not
have a significant role in the relationship between project success and laissez-faire and
authoritarian leadership. It shows that to enable the success of a project the
multidimensional contribution of the top management on the project has a crucial impact
by strengthening the relationship between project success and project managers' leadership
styles.
