The Effectivness of Project Management Processes on Performance of Construction Projects: Case Study Analysis in Selected Companies in Addis Ababa
通过对比埃塞俄比亚一个成功和一个失败建筑项目的案例，发现规划流程以及质量、时间、成本和沟通流程的有效应用对项目成功至关重要。
Project management processes are categorized into 5 process groups and 10 subject groups. Within these groups, depending on the type of project, there are 39 processes to be implemented in the project. But, in many instances of projects in Ethiopia, those 39 processes had been applied neither in full nor in significant extent. Recently, research findings show that more than 70% of projects in Ethiopia are under failure category. Therefore, to overcome these problems a research is done to identify which processes of project management are effective for attaining success of a project by studying cases of a successful and failed project. After evaluating their accomplishment a building construction project called Africa Union Office Complex and Conference Centre and Ethiopian Maritime and Transit Service Building Construction Project were selected as successful and failed projects, respectively. The researcher used questionnaires to collect data from respondents. The research result revealed that 70% of planning and 88% of quality, time, cost and communication processes were applied in a successful project as compared to a failed project. Based on these research findings the researcher concluded that planning process from the process group and Quality, Time, Cost and Communication processes from the subject group are effective in realising success of a project.
