This project aims to implement a new system that performs shear testing without destroying the piece, thus reducing the scrap percentage. The DMAIC methodology was used to enhance the shear testing process. DMAIC is a concept that measures defects in business processes and improves profitability. DMAIC stands for the process's five main steps: Define, Measure, Analyze, Improve, and Control. This research seeks to improve the measurement process of shear tests. This is important for the process because it will reduce scrap, decrease the error percentage when measuring shear in each piece that undergoes welding processes, and provide a more accurate value, thus improving quality. The DMAIC methodology provides a structure and tools to enhance a process by optimizing and stabilizing the business process. In this case, it would involve eliminating destructive tests and reducing scrap percentage due to shear tests. Key Terms — Optimization, Residential Breakers; Shear Test; Welding Process.Item Authorized Medical Allowance Lists (AMAL) and the Authorized Dental Allowance List (ADAL) Review Process in the Department of the NAVY(Polytechnic University of Puerto Rico, 2024) Rodríguez Rivera, Pedro O.; González Miranda, Carlos J.The AMAL and ADAL are clinically driven documents that specify the minimum quantity of equipment and consumable items required by the U.S. Navy’s operating forces Health Services Departments. These lists ensure that the necessary medical capability and capacity are met based on Required Operational Capabilities (ROC) and Projected Operating Environment (POE). To enhance the AMAL/ADAL Review process, the study employed the Define Measure Analyze Improve Control (DMAIC) methodology. Process Mapping was used to visualize the steps in the current process, identify areas with limited value, and understand the flow of materials and information. The goal is to create an improved process flow, establish roles and responsibilities, and align with the National Defense Authorization Act (NDAA) requirements. In summary, DMAIC provides a structured approach to optimize and stabilize business processes, ultimately enhancing medical and dental readiness for Navy forces.
