This project analyzes the challenges faced by Latino Engineering after a change in ownership, focusing on the decline in quality and customer satisfaction. The assignment proposes a continuous improvement plan to address these issues. The plan utilizes the POTI (Process, Organization, Technology, and Information) model to identify root causes of defects and complaints, and then employs 7 QC (Quality Control) tools, including Pareto diagrams, cause and effect diagrams, histograms, control charts, scatter diagrams, graphs, and check sheets, to develop strategies for improvement. The project emphasizes the importance of leadership, employee motivation, technological upgrades, and information system enhancements to achieve higher quality standards and regain customer trust. The solution provides a detailed framework for continuous improvement, aiming to reduce rework, enhance efficiency, and establish a culture of ongoing quality enhancement within Latino Engineering.
