Submitted in fulfillment of the requirements for the degree of Master of Management Sciences (Business Administration), Durban University of Technology, Durban, South Africa, 2017. / The South African mobile telecommunications industry has grown into a multi-billion rand industry that employs thousands of people and connects millions of people across the globe. In order to accomplish the latter, multi-million rand capital projects must be initiated and successfully executed. It is against this background that this study investigated the factors influencing the effectiveness of project managers in the telecommunications industry in South Africa. The target population of the study consisted of project managers in the five telecommunications companies in South Africa who were registered with Project Management South Africa (PMSA). The primary data, which was collected personally by the researcher through self-administered questionnaires, was analysed using the Statistical Package for Social Sciences (SPSS), Version 23. The study revealed, inter alia, that most project managers in the telecommunications industry in South Africa perceived negotiating skills, technical knowledge, and management style as being most important for effectively confronting the many challenges faced by them, inter alia, scope management, quality management, and risk management, so that projects were successfully executed. There was unanimity amongst the project managers that training in project management had a positive impact on the performance of project managers. Although three out of every four project managers possessed a postgraduate qualification, the majority of project managers were of the view that a diploma was adequate to practice as a project manager in the telecommunications industry in South Africa. However, it was more important for project managers to possess project management qualifications. In addition to the above, an analysis of the results revealed that, in order of importance, the effectiveness of the project managers in the telecommunications industry in South Africa was influenced by communication skills, technical skills, education skills, leadership skills, interpersonal skills and negotiating skills. / M

M.Tech. (Construction Management) / The construction industry is an important sector in the development and economic progression of South Africa. Moreover, projects in the South African construction industry involve different individuals and organizations that collaborate to achieve a specific task at a specific time. Hence, leadership is essential in any construction organization to achieve organizational goals and to promote individual professional achievement in the industry. This study evaluates different leadership style practices of construction and project managers in the South African construction industry. The study further investigates leadership development approaches in the industry. The data used in this research were derived from both primary and secondary sources. The secondary data were collected via a detailed review of related literature. The primary data were collected through a structured questionnaire aimed at 150 construction and project managers in the South African construction industry. The study revealed that project and construction managers in the South African construction industry prefer transformational leadership, followed by transactional and democratic leadership. It was also revealed that communication skills, vision, honesty and reliability are some of the important traits of a project leader. This study also suggests ways in which leaders can be developed in the construction industry. Formal leadership training, mentoring and personal development are highlighted as some of the ways in which construction leaders can be developed in the construction industry. It is therefore recommended that construction organizations in South Africa should invest more than they are currently doing in leadership development programs, so that future project and construction managers can be developed to be effective leaders in the industry. The current study contributes to the body of knowledge on the subject of leadership in the construction industry. The value of the study is to facilitate and understand the different leadership style practices in the construction industry and to determine the relationship between leadership styles and project success. This research also provides new information on how to improve leadership in the South African construction industry.
