The study underlines the significance of Business Process Improvement (BPI) and explores various frameworks and methodologies aimed at enhancing business efficiency. Specifically, the research employs Cause-and-Effect Analysis with a Fishbone diagram to examine and understand the underlying issues of a process in need of improvement. Data, both quantitative and qualitative, was collected and methodically analyzed to investigate the root causes. The "5 Whys" methodology was utilized to identify key factors and subfactors contributing to inefficiencies. These factors were then prioritized using a Pareto chart, targeting the most significant issues that account for 80% of the process inefficiencies. Statistical analysis pinpointed the bottlenecks, facilitating the formulation of multiple recommendations. It was concluded that implementing a lean process design could resolve approximately 80% of the identified inefficiencies. The research encountered certain limitations and obstacles, which are acknowledged as potential avenues for future research.enbusiness process improvement, subcontractor, facility management, site manager, cause-and-effect analysisDissertationDr Sa'ed SalhiehProfessor Alaa Ameer
