| dc.description.abstract | Systems engineering (SE) is an interdisciplinary approach which is helpful to realise a successful project in terms of its lifecycle performance. It is widely used in different types of projects across the world in the last decades and its effectiveness is confirmed by many published case studies. Nevertheless, these evidences are limited in the effectiveness of adopting SE on Design- Bid- Build (DBB) and Design-Build (DB) project delivery methods and there is no any evidence at hand that shows whether SE has a potential to improve EPC project performance. Therefore, this thesis work is an attempt made to work out how SE could be embedded on EPC projects from the employer perspective and to justify the likely benefit gained or missed from adopting SE at Addis Ababa LRT project. In EPC projects, establishing comprehensive and correct employer requirement helps the employer to reduce cost due to variation orders and the uncertainty emerged from failure of anticipating the lifecycle performance of the underdeveloped system. Meanwhile, it is believed that adopting SE for employer requirement management would be unequivocal solution for reducing the emerged problems. Hence, two main research questions were formulated initially and, finally, were addressed by the result obtained from the data collected under the selected indicators. The results obtained from the data analysis can be summerised in the following three statments. (1) The appeared budget overrun or the schedule delay would be reduced if adequate systems engineering application was employed at the early stage of the project development. (2) If SE approach were adopted to Addis Ababa LRT project, the project would deliver a system that performs better during its lifecycle. (3) If the employer had used SE approach for establishing employer requirement, design verification and approval, and to test the final product, the uncertainty coming from the complexity of the project would have been reduced and satisfaction of the stakeholders would have been improved. The findings of this thesis reseach show that the employer has missed significant amount of opprtunities that would be provided by using SE and is heading to face the challenges emerged dueto these lost opprtunities. Consquently, it is suggested to adopt SE during the operation phase of the project and at the expected phase II extension project for addressing the appeared problems at phase I and to enjoy the likely benefit gained by using SE.
