Item Lean Manufacturing Implementation to Improve Process Capability and Performance(Polytechnic University of Puerto Rico, 2022) Orama Negrón, Yanairy; Morales, José A.Industries has been continuously evolving with the change in tendencies and market growth of products. To be capable of maintaining the organization competitiveness, in front of an aggressive market, production capability and cost reduction is desired. Company X is dedicated to the design and manufacturing of customizable packaging and promotional merchandise. It was identified some factors affecting the deliverables of the production floor, such as inefficient layout design. Lean manufacturing is a tool widely used by many industries to reduce waste in processes. Applying this tool into production processes, allows to reduce wastes in process and to reduce production costs and defect ratio. DMAIC (Define, Measure, Analysis, Improve and Control)was the methodology used to improve the outputs of the production floor of Company X. At the end of the project an improvement of 15% on the productivity was observed; in addition, the defect rate was reduced by 33%.Key Terms: 5’S,DMAIC,Lean Manufacturing, Waste Reduction.Item Mejora en el Proceso de Limpieza en los Equipos de Manufactura(Polytechnic University of Puerto Rico, 2022) Rivera, Ivette; Morales, José A.Durante estudios de tiempo en los procesos en una farmacéutica en Puerto Rico se identificó un tiempo prolongado en la ejecución de limpieza de la Compresora que es compartida con varios productos .Por esta razón la planta se propuso como objetivo reducir el tiempo de la limpieza para poder manufacturar más lotes.Para mejorar la limpiezase utilizó la metodología de validación de limpieza y “Lean Six Sigma”. La limpieza fue mejorada y validada demostrandola remoción de residuos. La reducción de tiempo en la limpieza fue de 50% y un 54% en el costo ya que se disminuyó el consumo de utilidades y de tiempo. Esta reducción incrementó la cantidad de lotes manufacturados. Por tanto, las mejoras a la limpieza fueron satisfactorias quedando pendiente los “Hold Times”. Como parte de las regulaciones para los procesos de limpieza en la industria farmacéutica se espera que se valide los “HoldTimes”.

The main objective was to reduce the number of samples sampled for X and Y areas. Also, according to the evaluation those samples quantities already stored were reduced and the sample orientation at storage was changed. The implementations were performed with data integrity, high quality, within Regulatory and Quality Management approvement. Plan Phase was used to investigate the situation where the Visual Management5’S was applied. During the data analysis was implemented a solution plan on the Do Phase. Meanwhile on Check Phase it was evaluated that implementation accomplished the project milestones. Though on Act Phase a cost saving of $85,784.82 was met and around 50% of samples sampled were reduced. It was confirmed with a Hypothesis Test for the Mean with alpha 5% and it was found that the reduction was completed.

Many documentation errors were constantly found on acceptance records at the Product Release-to-Packaging stage. A Flow Diagram and a Root Cause Analysis were performed to identify deficiencies on the process that were leading to errors. Four different types of wastes were found multiple times in the in-process of spinal needles, constantly interrupting the flow of work and information. A continuous flow is achieved by re-designing the in-process documentation. The new acceptance record avoids most of the documentation mistakes by replacing handwritten forms with electronic forms, ultimately, improving productivity and achieving a leaner process. Key Terms⎯ Continuous Workflow, Good Documentation Practices, Lean Manufacturing, Root Cause Analysis.Item Process Time Reduction in Manufacturing Areas: Visual Valves Identification on Manufacturing Area specifically on Media Prep Area, Media Preparation tanks to Pursue Agility on the Visual inspections required before, during and after the Media Prep Solution are Prepared(Polytechnic University of Puerto Rico, 2022) López, Jaymarie; Morales, José A.Time of production process and associate activities were evaluated for Media Prep manufacturing process on Juncos, P.R. The voice of the customer requested reduced time inspection process before, during and after batching preparative activities and process. DMAIC methodology was used to evaluate the production costs. Fishbone, Scatter, Grant Charts, and other tools were used to determine what was the possible cause of highest time associates take to find valves, and equipment in gray area, even though the valves are identified with its proper part number. Equipment and material identification were most probable causes. Improvements in procedures and identification tags were used to perform and established the new color code tags, based on the function and type of addition of the valves. Evaluated process and defined the color code for the valve and established a 5S in the gray area reduced time and cost, also process became more agile and effective. Key Term⎯ Agility, DMAIC, Grant Chart, Lean Manufacturing.Item Change Control Routed with Missing Information Delaying Approval and Implementation Date(Polytechnic University of Puerto Rico, 2022) Álvarez Rodríguez, Bianca; Morales, José A.The approval of manufacturing change control for MedDevice Inc., is currently acting lower than target(15 business days). Based on a 12-months data review, the lead time of approval of a change is approximately 36 days. This means that 25.8% of changes were routed for evaluation without the necessary information. The DMAIC methodology was used to determine what is causing the delay. The following possible causes were identified as part of the evaluation: (1) missing information i.e., Manufacturing Plan, Validation documents, and Product affected is not included. (2) Volume of changes being routed. (3) Time for identification and number of required approvers by type of change. During control phase, lead time for four months (Quarter 2) was collected, and results demonstrate a reduction of less or equal to 33 business days. The project goal was to reduce approval lead time process from 36 to 33 days by end of Quarter 2.KeyTerms⎯Change Control, Continuous Improvement, DMAIC, Lead Time.Item Monomer’s Residuals Test Elimination for Soft Acrylic Buttons at Polytechnic University of Puerto Rico(Polytechnic University of Puerto Rico, 2022) Vargas Lugo, Bethzaily; Morales, José A.In the cataract surgery, the natural lens in the eye is replace with an Intraocular Lens. Five monomers (EA/EMA, TFEMA, EGDMA, UV Chr) are mixed to produce the soft acrylic lens. Residual monomer testing measures the amount of monomer and crosslinker not polymerized or removed by annealing process. During the last years residual monomer testing become a high-cost test due to equipment maintenance, chemical purchases, and spare parts cost. Historical data was collected from the residual testing for Optiblue from January 2019 up to May 2020and Opal from June 2018 up to May 2020. DMAIC methodology was used in this analysis. Process Performance Index (Ppk) value varies from 5.62 to 49.52 for Opal and 2.09 to 30.00 for Optiblue, which confirm annealing process is a capable and is in statistically control. Trend analysis was performed, and no negative trend was observed. Therefore, the monomer residual test can be eliminated.

The ingredient X oil, a non-psychoactive compound that has long been used for its therapeutic benefits, which include soothing skin, treating joint injuries and easing chronic pain, and for those properties the ingredient X is used in the formulation of this soap to validate that can be a useful ingredient. The analysis chart of the tests made to the soap made with a mixture of a few oils, sodium hydroxide, water and Ingredient X demonstrate a few components presents in the soap. A chromatograph evaluated by HPLC showed presence of Ingredient X in it.The validation that the soap contains Ingredient X in it certifies that soaps can be made with Ingredient X and that can be beneficial for the health of the skin.Key Terms -Natural ingredients, Natural Soap, Oils, SoapItem Quality in the Pharmaceutical Industries(Polytechnic University of Puerto Rico, 2021) Ilarraza Marzán, Vithya; Morales, José A.There are various techniques to measure the productivity of a certain economic activity, which is one that generates a profit from three phases: production, distribution, and consumption. One restriction in choosing the ideal method is the availability of statistical information. In some localities, there is still insufficient data to measure total factor productivity systematically and periodically. However, there is information that allows calculating productivity for the labor factor in economic activities, notably the pharmaceutical industry. The simplest measurement of labor productivity occurs when there is a company or an industry with a single product. In this case, labor productivity is expressed in units of that single product, either per man hours or per worker. This is an exceptional situation, since it is usually necessary to measure the productivity of a company, or a sector of activity where different products are produced or where the labor platform in the production lines.
