Reduction of 15% in Spare Parts Consumption Costs in Automated Non-Absorbable Suture Automated Process
(Universidad Politécnica de Puerto Rico, 2025) Valentín, Alejandra; Olivares Lugo, Luis A.
This project evaluates spare parts consumption behavior within automated non-absorbable suture Swaging and Winding operations, with the objective of understanding the drivers of cost escalation, variability, and maintenance-related usage. The project scope is limited to physical spare parts consumption associated with preventive and corrective maintenance activities, excluding procurement strategies, pricing effects, and changes in production throughput.
The Lean Six Sigma DMAIC methodology is applied to structure the investigation. The Define, Measure, and Analyze phases identify systemic drivers of overconsumption, highlighting gaps in preventive maintenance execution and opportunities for SOP optimization through clearer replacement criteria and standardized decision-making. The Improve phase focuses on mitigation strategies centered on standardization and technical alignment, while the Control phase introduces a business oriented control proposal designed to sustain improvements through governance, accountability, and continuous improvement rather than relying solely on procedural enforcement. Overall, the project establishes a repeatable, data driven framework for controlling spare parts consumption while maintaining equipment reliability and operational stability.
Modified Kugel Patch Lot History Record (LHR)
(Universidad Politécnica de Puerto Rico, 2025) Vázquez Méndez, Alondra; Flores Torres, Edgar; González Miranda, Carlos J.
Background
This Capstone project was conducted at Becton, Dickinson and Company (BD) – Humacao, within the Modified Kugel Patch manufacturing line. The project focused on the Lot History Record (LHR) documentation process, a critical component for ensuring product traceability, regulatory compliance, and audit readiness in a highly regulated medical device manufacturing environment.
Problem Statement
The current LHR documentation process showed a significant increase in documentation-related issues. Documentation non-conformances increased from 1% to 7%, while auditor holds rose from 32% (71 lots) in 2023 to 75% (50 lots) in 2024. The process required more than 445 manual entries per lot, containing redundant and unclear templates, and relied heavily on manual verification loops. These conditions resulted in excessive documentation time, high process variability, increased risk of GDP errors, and delays in lot release.
Project Objective
The objective of this project was to optimize the Modified Kugel Patch LHR documentation process by reducing non-value-added and non-value-added-but-required activities, improving documentation accuracy and traceability, and minimizing regulatory risk, while maintaining full compliance with FDA Quality System and OSHA workplace safety requirements. Methodology A structured Lean Six Sigma DMAIC methodology was applied. Key tools included process mapping, SIPOC, CTQ analysis, Voice of the Customer (VOC), time studies, Value Stream Mapping, Pareto analysis, Spaghetti diagrams, process capability analysis, and risk assessment using FMEA. These tools were used to identify root causes of documentation errors, quantify process inefficiencies, and prioritize improvement opportunities.
Proposed Solution (Future State)
The proposed Future State focuses on documentation standardization, elimination of redundant entries, consolidation of verification steps, and improved reconciliation practices. The improvements reduced documentation complexity, lower process variability, and strengthened data integrity while preserving all critical quality controls and regulatory requirements. Risk evaluation confirmed reduced operational risk, and the changes were classified as administrative and procedural, requiring no process revalidation.
Results and Impact
The proposed improvements are expected to significantly reduce documentation cycle time, auditor holds, and documentation-related non-conformances. Financial analysis estimates annual savings of approximately $106,346.50, driven by reduced rework, fewer investigations, decreased audit preparation time, lower paper usage, and improved labor efficiency. The Future State maintains full compliance with FDA and OSHA requirements while improving audit readiness and operational robustness.
Análisis de Alternativas para Modernizar el Sistema de Alarma de Incendio y Notificación Masiva del Edificio 29 en la Instalación PR012
(Polytechnic University of Puerto Rico, 2025) Marrero Llavona, Gloriam; Cruzado Vélez, Héctor J.
Este proyecto evaluó alternativas para modernizar el sistema de alarma contra incendios y notificación masiva del Edificio 29, una Reserva del Ejército de los Estados Unidos en Puerto Rico. El sistema existente presentaba obsolescencia tecnológica, deficiencias de cobertura y falta de cumplimiento con los requisitos actuales de seguridad. Para abordar esta situación, se analizaron tres alternativas de modernización: reemplazo total del sistema, modernización parcial e integración tecnológica. La evaluación se realizó mediante el método de matriz de decisión ponderada, considerando criterios técnicos, normativos, operacionales y económicos, incluyendo cumplimiento normativo, confiabilidad del sistema, continuidad operacional y capacidad de expansión futura. Los resultados obtenidos indicaron que el reemplazo total del sistema alcanzó la mayor puntuación global, destacándose por su desempeño consistente en los criterios de mayor relevancia. Palabras claves ⎯ Ciberseguridad, Continuidad operacional, Cumplimiento normativo, Matriz de decisión ponderada.
Improving On-Time Delivery Reporting Flow at Collins Aerospace
(Polytechnic University of Puerto Rico, 2025) Yapur Henjes, Gibrán; Cruzado Vélez, Héctor J.
On-time delivery (OTD) performance plays a critical role in aerospace manufacturing due to its impact on production schedules, customer commitments, and cost control. This project examined the absence of a standardized OTD reporting flow within a regulated aerospace manufacturing environment and evaluated
alternatives for improving delivery visibility and reporting efficiency. Using the Define–Measure–Analyze–Improve–Control (DMAIC) methodology, existing reporting processes were assessed, stakeholder requirements were identified, and reporting solutions were evaluated. The analysis revealed that fragmented data sources and manual reporting practices increased managerial workload and limited proactive risk management. An internal SQL-based workflow reporting solution was selected based on integration capability, data security, and sustainability. The project demonstrated that standardized, system-integrated
reporting improves data accuracy, reduces direct labor costs, and supports more effective managerial decision-making. Key Terms ⎯ DMAIC, SQL, utilization rate.
Sustainability Study of Galaxy Bowl by using new strategies of marketing, promotions and statistics to improve sales of food and beverages
(Polytechnic University of Puerto Rico, 2025) Mastrorosa, Gianfranco; Uribe Florez, Victor M.
This project focuses on informing people about the food and beverages sold at Galaxy Bowl (Universal Studios Orlando). In this project we worked in new marketing and promotion of their food and beverages to improve their sales based on those items. Cabana Bay is a popular resort since it is the only resort at Universal Studios which has a bowling alley, however people do not know that they are actually a full-service restaurant. Finally, lets Galaxy Bowl and its labors get a better sustainability based on food and beverages sales. After we did all the activities, we could obtain an increase on F&B sales by almost 15%.
