This report examines the application of system thinking principles to improve the operational efficiency of a public hospital's emergency department. The analysis begins with an overview of the current state value stream map and operational architecture, highlighting inefficiencies that lead to excessive patient turnaround times. The report identifies key system archetypes, such as delays in database operations, waiting room bottlenecks, and supply procurement issues, that impede performance. Based on these findings, a new operational flow is proposed, incorporating real-time database systems, optional waiting room scenarios, and combined initial examinations by nurses and doctors to streamline processes. The report details the expected consequences of these modifications, including a significant reduction in patient turnaround time, and concludes with recommendations for implementing the proposed changes. The goal is to enhance consumer loyalty, improve service quality, and increase the overall efficiency of the emergency care unit.
